The latest development of COVID-19 vaccine


Quick Navigation

The development of COVID-19

Coronaviruses are a large group of viruses that are known to cause diseases. Patients show different symptoms from the common cold to severe lung infections, such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The new coronavirus (nCoV) is a new type of coronavirus that has not been found in humans, such as the new type of coronavirus 2019-nCov in Wuhan, China. As the COVID-19 has developed so far, COVID 19 vaccine is about to be on the market.

On January 12, 2020, the World Health Organization officially named COVID-19 2019-nCoV. The COVID-19 is a new strain of coronavirus that has never been found in humans before.

Since December 2019, Wuhan City, Hubei Province, has continued to carry out influenza and related disease surveillance, and multiple cases of viral pneumonia have been found, all diagnosed as viral pneumonia/pulmonary infection.

Common signs of people infected with coronavirus include respiratory symptoms, fever, cough, shortness of breath, and difficulty breathing. In more severe cases, the infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death. There is no specific treatment for the disease caused by the new coronavirus.

But many symptoms can be managed, so treatment should be based on the patient's clinical condition. In addition, supplementary care for infected people can be very effective. Self-protection includes: maintaining basic hand and respiratory tract hygiene, adhering to safe eating habits, and avoiding close contact with anyone showing symptoms of respiratory diseases (such as coughing and sneezing).

The latest research results reveal the transmission characteristics of the new coronavirus: high infectivity and high concealment. A new study in Australia shows that the COVID-19 can survive on banknotes, glass and other surfaces for nearly a month.

People infected with the virus will have assorted symptoms. Some just have a fever or a mild cough, some will develop pneumonia, and some will have more serious symptoms or even die.

The fatality rate of the virus is about 2% to 4%, but this is a very early percentage and may change as more information becomes available. At the same time, this does not mean that it is not serious. It just means that not everyone who is infected with the virus will face the most serious consequences. The main transmission routes of the COVID-19 are respiratory droplets and contact transmission. The transmission routes of aerosols and feces-oral still need to be further clarified. According to epidemiological investigations, most cases can be traced to close contact with confirmed cases.

On August 27, 2020, WHO Director-General Tan Desai said that the epidemic affects the mental health of millions of people worldwide. Globally, mental health is already a neglected health problem. Nearly 1 billion people worldwide are affected by mental health problems of varying degrees, and superlative drinking causes 3 million deaths each year. But only a few people can have high-quality consultation and treatment. In low- and middle-income countries, more than 75% of people suffering from mental illness, neurological and drug abuse problems cannot receive any treatment. The WHO has called for a massive increase in investment in mental health.

COVID-19 Prevention and Solution

Suspected and confirmed cases should be treated in designated hospitals with isolation and protection conditions, and severe cases should be admitted to the ICU for treatment as soon as possible.

General treatment, including bed rest, supportive treatment, adequate calories, improving related examinations, and regularly reviewing chest imaging examinations. According to the patient’s blood oxygen saturation, timely effective oxygen therapy, including nasal catheter oxygenation, high-flow oxygen therapy, non-invasive or invasive ventilator support should be given; appropriate addition of antibacterial drugs should be given according to the condition.

The principle of treatment for severe and critical patients is to actively prevent complications, treat underlying diseases, prevent secondary infections, and provide organ function support on the basis of symptomatic and supportive treatment. The fundamental solution, however, that may solve the COVID-19 lies in the development of vaccines.

What is a vaccine?

Vaccines refer to biological products made with various pathogenic microorganisms for vaccination. Vaccines made with bacteria or spirochetes are also called bacterins. Vaccines are divided into live vaccines and dead vaccines. Commonly used live vaccines include BCG, polio vaccine, measles vaccine, and plague vaccine. Commonly used dead vaccines are pertussis vaccine, typhoid vaccine, meningococcal vaccine, cholera vaccine and so on.

The production time of different vaccines is different, and some vaccines may take 22 months to produce a batch. The development of a vaccine is a long and complicated process, and the cost is high. Vaccination is the most economical and effective public health intervention to prevent and control infectious diseases. It is also an effective means for families to reduce the occurrence of member diseases and reduce medical expenses.

It is estimated that immunization can prevent 2 to 3 million deaths caused by diphtheria, tetanus, pertussis and measles each year. Global vaccination coverage (the proportion of children worldwide who receive recommended vaccines) has remained stable over the past few years.

Vaccines are autoimmune preparations made of pathogenic microorganisms (such as bacteria, rickettsiae, viruses, etc.) and their metabolites through artificial attenuation, inactivation, or genetic modification to prevent infectious diseases. The vaccine retains the characteristics of pathogenic bacteria that can stimulate the animal's immune system. When animals come into contact with this innocuous pathogen, the immune system will produce certain protective substances, such as immune hormones, active physiological substances, special antibodies, etc.; when the animal comes into contact with this pathogen again, the animal’s immunity system will follow its original memory and create more protective substances to prevent pathogenic bacteria from harmfulness.

COVID 19 vaccine progress

The COVID 19 vaccine is a vaccine against the new coronavirus.

On January 24, 2020, the Chinese Center for Disease Control and Prevention successfully isolated China’s first strain of new coronavirus. At 20:18 on March 16, the recombinant COVID-19 vaccine was approved to start clinical trials. On April 13, China’s COVID-19 vaccine entered phase II clinical trials; on the same day, an expert group composed of more than 120 scientists, doctors, funders and manufacturers around the world issued a public declaration, promising to work together under the coordination of the World Health Organization to speed ​​up the development of COVID-19 vaccines.

On June 19, China’s first COVID-19 vaccine was approved to start clinical trials. As of July 20, there are currently about 250 candidate COVID-19 vaccines in development worldwide. On August 16, the COVID-19 vaccine from the team of Academician Chen Wei obtained a patent, which is the first in China. The patent application for this invention enjoys a priority review policy; on August 20, the clinical trial of China’s bio-COVID-19 vaccine under the Sinopharm Group was launched in Peru (Ⅲ Period); On October 8, China signed an agreement with the Global Alliance for Vaccines and Immunization to formally join the “New Coronary Pneumonia Vaccine Implementation Plan.”

As of October 20, 2020, China has vaccinated a total of about 60,000 subjects, and no serious adverse reactions have been reported.

Storage of COVID 19 vaccine

Once the COVID-19 vaccine is successfully developed and applied on a large scale, the storage of the vaccine will be an important issue. In order to be able to safely store the COVID-19 vaccine developed by Pfizer, states, cities and hospitals in the United States have begun rushing to buy ultra-low freezer. Some professional refrigerator manufacturers have warned that the supply of freezers in the United States is beginning to fall short of demand, and it will take several months to wait.


According to the cold chain management regulations of the immunization program, long-term storage of vaccines should be stored below minus 20 degrees Celsius; for short-term storage, they should be stored at 2-8 degrees Celsius.

Vaccine cold chain refers to the storage, transportation and refrigeration facilities and science equipment equipped to ensure the quality of vaccines during the operation from the vaccine manufacturer to the inoculation unit. Because vaccines are sensitive to temperature, every link from the department where the vaccine is manufactured to the site where the vaccine is used may fail due to high temperature.

At this time, medical freezers will be in short supply. The medical freezer is a professional cold storage that mainly stores and preserves drugs, vaccines, enzymes, hormones, stem cells, platelets, semen, transplanted skin and animal tissue samples, extracted RNA and gene libraries, and some important biological and chemical reagents.

Medical freezer is widely used in many industries and fields such as scientific research institutions, medical and health care, biopharmaceuticals, pharmacies, etc., and is an essential medical equipment. Medical freezers have strict temperature control devices, and their performance and uses are quite different from household freezers.

The medical freezer is used to store blood bags, medicines, reagents, etc., and can be used with other instruments to maintain low temperature in experiments such as protein extraction and shaking culture. As a regular refrigerator in the laboratory, it can store enzymes, blood products, nucleic acids, etc.

Ultra-low freezers are mainly used to store medicines, vaccines, enzymes, hormones, stem cells, semen, transplanted skin, and specimens drawn from the human body, gene clone libraries, and some important biological and chemical reagents. In the future, the main concern is the reliability of low-temperature freezers and the storage conditions. Nanomaterials will become a promising material in low-temperature freezers in the future. The monitoring system will also become an important part.

The COVID-19 vaccine developed by Pfizer must be stored at a very low temperature of at least minus 70 degrees Celsius for 6 months. If it is stored in a refrigerator at 2 to 8 degrees Celsius, it can only be stored for 5 days. This also means that most of the existing cold chain systems are difficult to meet the transportation needs of the vaccine.

The low temperature environment of minus 70 degrees Celsius can only be guaranteed by ultra-low freezers.

The ultra-low freezer adopts a dual-machine cascade form with two compressors. Its insulation material is polyurethane material, and the original Italian imported microcomputer precision controller is built in. The temperature can be freely controlled between -10 degrees and -80 degrees, and it has precise temperature control. In addition, it has a humanized design and is a drawer-type structure, which can be opened when fetching, which is convenient for storage of items.

The fields needing ultra-low temperature are not as many as those needing low temperature, but the fields needing ultra-low temperature are generally used for low-temperature experiments such as scientific research institutes or laboratories. The -80c freezers can store biological products, chemical reagents, plasma, vaccines, Strains and biological samples, etc.


The COVID 19 vaccine will be available in the future, and millions of people will be vaccinated against the COVID-19. The vaccine developed by Pfizer in the United States needs to be stored in an ultra-low temperature environment, which puts forward demanding requirements for the cold chain management of vaccine transportation. Ultra-low freezers will be needed.

What is the best mini freezer?

What is a mini freezer?

1. Definition

Mini freezer can keep your food and drinks cool and fresh. In addition to being used in homes and offices, it can also be used directly in cars. The size of a mini freezer is generally width 400 * depth 370 * height 490mm, width 435 * depth 432 * height 570mm, etc., and the volume is 20L, 35L, 40L, 42L, 46L, 48L, etc. Different brands of freezers have different sizes. It is recommended that you buy a mini freezer of 50 liters per capita.

The small freezer can conveniently store sandwiches, fruits, cosmetics and many kinds of items.

In 1910, the world's first household freezer with a compression freezer came out in the United States. In 1925, the Swedish Lido Company developed a household absorption freezer. In 1927, the United States General Electric Company developed a fully enclosed freezer.

As early as 2000 BC, ancient inhabitants of the Euphrates and Tigris river basins in Western Babylon had begun to pile ice cubes in the pits to freeze meat. In the Shang Dynasty (early 17th century BC to 11th century BC), Chinese knew how to use ice cubes to refrigerate food. In the Middle Ages, many countries had original freezers that put ice cubes in special water tanks or stone cabinets to preserve food. Until the 1850s, this type of freezer was still sold in the United States.

In the mid-17th century in the West, the word "freezer" entered the American language. Through the development of cities, ice trading has gradually developed. It was gradually used as food preservation of meat, fish and butter in hotels, hospitals, and some discerning city merchants. After the civil war (1861-1865), the ice brick was used in refrigerated truck and also entered civilian life. By 1880, half of the freezers were sold in New York, Philadelphia, and Baltimore.

At the beginning of the 19th century, inventors had a very rudimentary understanding of thermophysics, which is vital to refrigeration science. In the West, people believed that the best freezer should prevent the melting of ice, but such a very common view at the time was wrong, because it was the melting of ice that caused the cooling effect. Early people’s efforts to preserve ice, including wrapping the ice with blankets, were huge until the end of the 19th century, when inventors succeeded in finding the precise balance of insulation and circulation required for an efficient freezer. Common refrigerators include vertical freezers, horizontal freezers, desktop freezers, ordinary household refrigerators, and ultra-low freezers which are popular because of the COVID-19 vaccine.

2. Features of mini freezer

The small freezer can keep your food and beverages cool and fresh. The switch after turning the box is converted into a heating system, which can heat food to 65 °C. Equipped with a public connection wire and a car cigarette lighter connection wire means that you can keep food and drinks cool in the car, suitable for picnic or fishing. Once you have a mini freezer, you will want to put one in every room.

Adopting the new concept of space technology PELTIER effect, without the bulky, noise and fluorine pollution of the compressor, it has long life, cute appearance, small size and light portable belt, suitable for indoor and outdoor use.

Therefore, the product can not only be used in the home or office, but also directly in the car. The product has a cooling fin with a life of 85,000 hours, a DC fan with a life of 30,000 hours for heat dissipation to ensure the built-in product. Powerful cooling capacity: cooling: the lowest temperature can be 5 °C, 20-25 ℃ lower than the ambient temperature. Heating capacity: up to 65 °C.

3. Classification of mini freezers

One is to connect the freezer to the cigarette lighter through a cable, so that it can be cooled. This kind of freezer is mostly used for cooling and heat preservation, and can be used as an incubator in winter. Some car freezers can also be used at home, as long as it is connected to the home's 220V power supply.

The other is to use a group of energy storage boxes in the freezer to cool or keep warm. Put this group of energy storage boxes in a household freezer for 10 hours, and then put the energy storage box in the car freezer to cool, which can last 20 hours to keep the temperature below 15 degrees. Put this group of energy storage boxes in a microwave oven to heat for 120 seconds and put them in a car freezer, and it can be used for heat preservation. However, this kind of freezer has a small capacity holding up to six cans of Coke.

Uses of mini freezers

1. Office

The mini freezer is the ideal choice for your office. On your office desk, conference room, reception, etc., it can provide any professional with fresh and refreshing food and beverages at any time.

2. Home

When you watch sports programs on TV or your favorite daily comedy in the room, and at a party, the night drinks in the bedroom are connected with a 220-volt public standard wire. You can put the mini freezer in any corner.

3. Car

During holidays, family trips-using a standard 12-volt cable, you can connect the mini freezer to your car's cigarette lighter. So you can enjoy refreshing food and drinks in the car.

How to use the mini freezer?

1. Location

Due to the small size of the mini freezer, many people put it directly in the bedroom or under the desk for convenience. But in fact, it is easy to block the cooling vent of the mini freezer, which may cause malfunctions. Therefore, it is recommended that you choose an open place as much as possible and leave a little space around it. In addition, the radiation and cold of the freezer can easily affect your body, so it is recommended that you place the mini freezer in the living room as far as possible.

2. Power

Many people will use the mini freezer in the car. At this time, the power supply needs to be paid special attention: Generally speaking, the mini freezer needs to use the attached DC power supply in order to assure safety in the car. Never use it on 24V motorhomes or buses, otherwise serious fire accidents may occur.

3. Care

Most of the water vapor comes from the air. When people store food and open the freezer, the indoor air and the air in the freezer exchange freely, and the humid air in the room quietly enters the freezer. Part of the moisture comes from foods stored in the freezer, such as cleaned vegetables and fruits placed in fresh-keeping boxes. The moisture in vegetables and other foods evaporates and condenses into frost when cold.

Especially in summer, the indoor temperature is high, the humidity is high, and the temperature difference between the room temperature and the freezer is large. When the freezer is opened, a cool air flows from the inside to the outside, and the indoor air burrows into the freezer. In a few moments, a layer of hoar frost formed on the surface of the freezer. People have also found that even if there is nothing in the freezer, a thick layer of frost will form in the freezer that is often opened. It can be seen that a large part of the water vapor in the freezer comes from the water vapor in the air.

Some freezers require defrosting. Manual freezer defrosting is time-consuming and laborious, with poor defrosting effect. Here I recommend a defrosting trick to you. Cut a piece of slightly thick plastic film according to the size of the freezer compartment of the freezer and stick it on the frosted wall of the freezer compartment without any glue. When defrosting, take out the food in the freezer temporarily, then peel off the plastic film and shake it, and all the frost will fall off, then re-attach a film.

4. Clean

Just like ordinary household freezers, mini freezers will also have mildew and smells, and they need to be cleaned and maintained regularly. To avoid discoloration, you cannot use irritating cleaning fluids such as alcohol or delustering liquid. Just use a rag and scrub it with water. When scrubbing, unplug the power first to avoid electric shock, and then empty the food and beverages in the freezer.

5. Energy saving

A. Keep away from heat sources and keep gaps

Every time the temperature around the freezer increases by 5°C, its internal power consumption will increase by 25%. Therefore, it should be placed as far as possible from heat sources, preferably in a ventilated and shaded place. Do not put hot food directly in the freezer, put it in when it reaches room temperature. The food in the freezer compartment is best packaged in plastic bags, which can be frozen quickly and prevent moisture from turning into frost; the food should not be packed too full, and there should be a gap between the freezer wall to facilitate flow Air-conditioning.

B. Avoid frequent door opening

If the door is opened too frequently, on the one hand, the power consumption of the freezer will increase significantly, and at the same time the service life of the freezer will be reduced. Because the door of the freezer is large, the cold air inside the box escapes, and the warm and humid air outside the box enters, which will increase the temperature inside the box. At the same time, the moist air entering the box is easy to accelerate the frosting on the surface of the evaporator and thicken the frosting layer. Since the thermal conductivity of frost is much smaller than that of the evaporator material, it is not conducive to heat conduction, causing the temperature in the box to drop slowly, the working time of the compressor increases, the wear is accelerated, and the power consumption increases.

If the thickness of the frost layer on the surface of the evaporator is greater than 10 mm, the heat transfer efficiency will drop by more than 30%, resulting in a significant decrease in the cooling efficiency. In addition, when the door of the box is opened, the lighting in the box is turned on, which consumes electric energy and emits heat, which is obviously not conducive to energy saving.

C. Keep fresh in case of power outage, and use power at staggered peaks

If you are worried about the "power shortage" caused by the peak power consumption period, we recommend that you better use a freezer with the function of "time-by-hours electricity, power failure preservation". This kind of freezer can still keep fresh in the case of power cuts for up to 20 hours; moreover, its "time-by-hours meter" function can avoid cooling during peak electricity consumption periods with expensive electricity prices, and automatically achieve "avoid peak electricity consumption".

Maintenance of mini freezer

  1. The freezer should not be overfilled, and proper space should be left so that the air-conditioning can penetrate all stored products. In addition, the freezer should be disinfected regularly. Wipe it with dilute bleach water or 0.1% potassium permanganate water for 3-4 weeks. At the same time, it is necessary to clean the freezer regularly, especially the filter, where dirt and germs often accumulate.
  2. Always clean the dust on the back or bottom condenser and compressor of the freezer. You can use a vacuum cleaner or a brush to remove dust. Be careful not to wipe the dust on the freezer and compressor with a damp cloth.
  3. When the freezer is out of service for a long time, the power should be cut off first, all the food in the box should be taken out, the inside and outside the box should be cleaned, and the door of the box should be opened for a few days to fully dry the box and dissipate the peculiar smell in the freezer.
  4. Check the drain pipe. If the drain pipe is blocked, water will leak into the freezer. Poke the drain pipe with an iron wire to remove the accumulation on the drain pipe.
  5. Don't neglect the cleaning of the door seal strips. Dilute the bleach with 10 times the amount of water and then clean it with a toothbrush. Finally, rinse off the bleach with water. Dirty strips are easy to age, which will affect the airtightness of the freezer and increase power consumption.
  6. Check vibration, noise and compressor temperature. Touch the compressor shell during operation, there should be no obvious sense of vibration.
  7. Check whether there are cracks in the power cord to prevent leakage.
  8. Clean and dry the inside and outside the freezer with warm water or neutral detergent, and open the freezer door to ventilate and dry for one day.


Nowadays, mini freezers have become a good partner for many people in trips: it is convenient to use, easy to carry. It is very suitable for indoor, office or car use. Mini freezers can not only store many types of food, but also heat or freeze them, which can be described as a good product for home and travel.

Top 10 somatic cell counter over the world

Quick Navigation

Somatic cell

1. Definition

Somatic cells in raw milk are usually composed of macrophages, lymphocytes, polymorphonuclear neutrophils and a small amount of breast tissue epithelial cells. The total number of somatic cells (scc) contained in each milliliter of raw milk is a quantitative indicator of its quality. And somatic cell counter can count the somatic cells in the milk. Taking raw cow milk as an example, under normal circumstances, there are about 20,000 to 200,000 individual cells per milliliter of raw cow milk. However, when the lactation system is attacked by bacteria, infected and damaged, the number of white blood cells will increase significantly to 500,000/ml to 1 million/ml or even higher.

The concentration of somatic cells is also closely related to animal husbandry management and food safety. In animal husbandry, it directly reflects the udder health and potential milk production capacity of dairy cows; in food safety, it is closely related to the quality, flavor, and elements of milk. Accurate counting of somatic cells in raw milk is very important for livestock health management and milk quality monitoring.

What does somatic cell counter mean?

1. Definition

The somatic cell counter is a high-end instrument, especially for the dairy industry. It is mainly used in the quality control and product development of various dairy products, as well as the accurate counting of somatic cells in milk to improve the evaluation of the quality of liquid milk and provide quantifiable scientific data to the prevention and treatment of diseases in dairy cows in the pasture.

2. Testing indicators

The somatic cell counter for milk can count the content of somatic cells in raw milk to guide pasture management and dairy product development.

3. Scope of application

  1. The primary tool for ranch management
    In order to meet the requirements of livestock farms to improve the quality of raw milk, it is necessary to know the right information about the physiological condition of each cow. The milk yield component content and somatic cell content data obtained by this method can be used for: feeding optimization; breeding selection; early detection of subclinical mastitis.
  2. Early detection of subclinical mastitis in dairy cows can reduce losses
    Dairy cow mastitis is the most expensive dairy cow disease in the pasture. Veterinary expenses, antibiotics, retained milk, reduced production, lower milk purchase prices, and removal of sick cows, etc. The average loss per case is about $250-300.

    Clinical mastitis is the abnormal milk secretion of dairy cows with the breast enlargement. Subclinical mastitis does not cause visible changes, so it is more difficult to detect. But in the subclinical mastitis stage, the milk production of dairy cows has been greatly reduced. When one cow in the herd has symptoms of clinical mastitis, 15-40 cows suffering from subclinical mastitis, which means that the potential loss caused by undetected infection is enormous.

    The best way to find subclinical mastitis is to follow up the somatic cell record of each cow's milk sample month by month, just like the DHI dairy cattle breeding improvement organization.
  3. Ensure better product quality, shelf life and profit
    From the perspective of the dairy industry, the benefits of grading the purchase of raw milk based on somatic cell content are obvious, because raw milk with high somatic cell content can lead to:

    A. The content of protein, fat and lactose is reduced, resulting in a decrease in cheese production, etc.
    B. Increased lipase activity and free fatty acid content lead to rancidity of finished products and shortened shelf life
    C. Increased levels of immunoglobulin have side effects on milk fermentation
    D. The increase of sodium and chloride will produce unpleasant salt taste

How do you calculate somatic cells in milk?

1. Existing detection technology

The existing somatic cell count for milk detection technology mainly targets bovine somatic cells, including indirect and direct methods.

The indirect method is mainly to detect the changes in the physical and chemical properties of milk caused by the increase of somatic cells, thereby indirectly reflecting the total number of bovine somatic cells; the direct method directly detects and counts the cells.

Common indirect methods include California Cell Count (CMT), Wisconsin Mastitis Test (WMT), viscosity method, etc. They all use surfactants to release DNA in cells and target DNA aggregates and micelles. The main drawback of these methods is that the above-mentioned physical and chemical characteristics are not typical enough to measure colloids and viscosity. Large errors will occur when the milk is not fresh, the fat content is too high, and the temperature difference is too large.

The most classic of the direct methods is the manual microscopy method, but because its operation relies too much on manual labor, it is gradually replaced by flow cytometry. The flow cytometry technology is to dilute and drive the cells that have been pre-fluorescently stained in the sheath fluid, so that they can be accurately counted one by one through the optical detection system. As the most advanced cell detection technology at present, it has fast detection speed and high accuracy, but it also has many defects, such as complicated operation process, high equipment unit price and high use cost, and it is impossible to observe cell morphology.

2. Six types of somatic cell counting methods (mainly for raw milk)

  1. Microscopy
    1. Principle
      The fresh milk to be tested is smeared on a glass slide to form a film, dried, stained, and the cells whose nuclei can be clearly stained with methylene blue are counted under a microscope.
    2. Instruments and reagents
      1. Microscope: magnification X500 or X1000, with graduated eyepiece, micrometer and mechanical stage;
      2. micro syringe;
      3. glass slide;
      4. water bath;
      5. electric furnace;
      6. sand core funnel;
      7. hair dryer;
      8. incubator.

        Reagents: 95% ethanol, tetrachloroethane or trichloroethane, methylene blue, glacial acetic acid, boric acid.
    3. Method steps
      1. Add 54 ml of ethanol and 40 ml of tetrachloroethane into a 250 ml Erlenmeyer flask and shake well. Heat it in 65 °C water for 3 minutes, take it out and add 0.6 g of methylene blue, mix well, and place it in the refrigerator after cooling. After taking it out, add 6 ml of glacial acetic acid, mix well, filter with a sand core funnel, put it in a reagent bottle, and store at room temperature for later use.
      2. The collected raw milk should be stored at 2-6° C. If it is not determined within 6 hours, add boric acid for antisepsis. The concentration of boric acid in the sample is not more than 0.6g/100mL. Store under refrigerated conditions (2-6℃) for no more than 24 hours.
      3. Heat the raw milk in a 35 °C water bath for 5 minutes, mix it and cool it to room temperature to prevent the unevenness of the sample from interfering with the measurement results such as fat floating.
      4. After cleaning the glass slide with ethanol, wipe it dry with lens paper, flame it to dry, and cool to room temperature.
      5. Use microinjection to extract 0.01 ml sample, inject the sample flatly on the outer glass slide, immediately place it in the incubator, and place it horizontally for 5 minutes to form a uniform thickness sample film. Bake to dry on an electric stove, immerse the dried sample film on the slide in the staining solution for 10 minutes, take it out and air. Immerse the dyed sample membrane in water to wash away the remaining dyeing solution, and keep it dustproof after drying.
      6. Fix the glass slide on the microscope stage, using natural light or use electric light source, condenser lens, oil immersion high power lens in order to increase the intensity of transmitted light.
      7. The unidirectional moving mechanical stage counts the chromosomal cells on the slides in each field of view. Somatic cells that are clearly in the field of view or more than half of the shape in the field of view are used for counting, and the number of somatic cells should not be less than 400.
  2. CMT
    1. Application
      CMT is mainly used for the rapid diagnosis of latent mastitis in lactating dairy cows, the routine monitoring of breast health status of lactating dairy cows, the general survey of the incidence of latent mastitis in lactating herds, and the assessment of the hygienic quality of fresh milk.
    2. Principle
      The principle is that under the action of surface-active substances and alkaline drugs, somatic cells in the milk are destroyed and DNA is released, which further acts to cause the milk to precipitate or form a gel. The more somatic cells, the more precipitation or gel produced, which indirectly diagnoses the degree of mastitis and inflammation. This method is an internationally accepted method for the diagnosis of recessive mastitis, which is characterized by simplicity and speed.
    3. Method
      1. Sampling is collected from the milking area to be inspected, discard the first two milks, and squeeze the milk samples into the inspection cups of the inspection tray.
      2. Tilt the test tray (about 60 °C), discard the excess milk, and leave about 2 ml of milk sample in the test cup.
      3. Add 2 ml of diagnostic reagent (diluent) for dairy cows into each test cup.
      4. Shake in horizontal concentric circles for 10-30 seconds to fully mix the milk sample with the diagnostic reagent for dairy cows.
    4. Judgment criteria
      After CMT and milk are fully mixed, it is judged based on the presence or absence of agglutinates and the amount and properties of the agglutinates.

      Negative (-): The number of cells is 0-200,000/ml: The mixed solution is liquid. When the test plate is tilted, the liquid moves smoothly and there is no sediment on the bottom of the cup.

      Suspicious (±): The number of cells is 150,000-500,000/ml: The mixture is liquid. When the test plate is tilted, a small amount of sediment appears at the bottom of the cup, and the sediment disappears immediately after a little shake.

      Weak positive (+): The number of cells is 400,000-1.5 million/ml: A small amount of thin viscous sediment appears on the bottom of the cup, but it is not gelatinous. When the test disk is tilted, the sediment is scattered on the bottom of the dish and has certain adhesion.

      Positive (++): The number of cells is 800,000 to 5 million/ml: The bottom of the cup has a large amount of sediment, which is thicker and has a small amount of jelly. When the test plate is tilted, the sediment obviously adheres to the bottom of the cup. It is difficult to flow. When rotated and swayed, the sediment will be concentrated.

      Strong positive (+++): The number of cells is more than 5 million/ml: Most or all of the mixture in the dish forms obvious gelatinous aggregates, which almost completely adhere to the bottom of the dish. When the test disc is rotated, the aggregates appear. The lumps are difficult to disperse.

      Acidic milk (y): The milk is yellow, rancid. (mastitis)

      Alkaline milk (P): The milk is dark purple, accompanied by a decrease in milk production (mastitis); when the milk is mixed with alkali, the milk tends to be dark purple.
  3.  Conductivity method
    1. application
      Mainly used to judge cattle udder disease
    2. Principle
      The conductivity of cow's milk is related to the composition, especially the chloride ion and lactose content. When the chloride ion content in milk increases or the lactose content decreases, the conductivity of the milk increases.

      When the conductivity of normal milk is generally 0.004-0.005S at 20 °C. If it exceeds 0.006S, it can be considered as sick milk. Since milk contains salts, it is conductive. The number of ions in the milk will affect the conductivity, of which sodium, potassium, and chloride ions are the most influential.

      When the cow's lactic acid failure or mastitis milk produces lactic acid or salt content increases, the conductivity is higher than that of normal milk. Therefore, electrical conductivity can be used to indirectly test mastitis milk.
  4. Viscosity method
    1. Principle
      The viscosity of milk is 0.0015-0.0020 Pa.s at 20 °C. The internal factors affecting milk viscosity are the content of fat and protein in milk. If the content of fat and protein is high, the viscosity of milk is also high. The higher the dry matter content, the greater the viscosity of the milk. It is also affected by degreasing, sterilization, homogenization, etc.

      At the same time, the viscosity of cow's milk is also affected by temperature. As the temperature increases, the viscosity decreases. When the temperature is lower than 60 °C, the higher the temperature, the lower the viscosity; when the temperature is higher than 60 °C, the protein denatures, and the higher the temperature, the greater the viscosity.

      In addition, the viscosity of colostrum, and milk, and diseased milk are all higher than normal milk. Therefore, the viscosity can be measured to indirectly reflect the number of somatic cells.
  5. Fluorescence photoelectric counting method
    1. Principle
      The somatic cells in raw milk are fluorescently stained. After a series of lenses and filters are processed under special fluorescence, they are projected into the lens, and then the sample is photographed, read, analyzed and displayed.
    2. Features
      1. Strong operability: simple operation, convenient use, accurate results, and operators can start operation after simple training.
      2. Strong operability: simple operation, convenient use, accurate results, and operators can start operation after simple training.
      3. Strong operability: simple operation, convenient use, accurate results, and operators can start operation after simple training.
      4. Supporting software: the instrument has built-in statistical software to automatically store and analyze the testing data.
  6. FCM
    1. application
      Flow cytometry (FCM) is a fast, accurate and objective technology developed in the 1970s that can simultaneously detect and quantify multiple characteristics of a single particle (usually a cell). The dairy industry mainly uses flow cytometry to detect the total number of somatic cells and bacteria in milk.
    2. Technology
      The flow cytometer is a new high-tech instrument that integrates laser technology, electronic physics technology, photoelectric measurement technology, electronic computer and cell fluorescence chemistry technology.
    3. Structure
      Its structure is generally divided into 3 parts: sample chamber and liquid flow drive system; laser light source and optical system; signal detection, storage, and data processing system.
    4. Principle
      The sample solution stained by the staining solution is pressed into the center of the nozzle through the sample tube, and the cell-free sheath solution is also pressed into the nozzle to form a sheath solution stream surrounding the cells, so that the cells enter the sample chamber in a single row, intersecting vertically with the laser beams (wavelength 488 nm) in the horizontal direction.

      The stable liquid flow propulsion device makes the sample arranging in a single row, and each cell passes through the laser irradiation area in an equal time. After the fluorescently stained cells are irradiated, two signals are generated. One is the scattered light signal and the other is forward. The forward scatter (FSC) is generally proportional to the size of the cell; the side scatter (SSC) is related to the granularity and complexity of the cell.

      The other is a fluorescent signal, the emitted fluorescence is directly proportional to the binding site. Different types of optical signals are received by corresponding optical detectors. The optical signal is collected by the electrical system, converted into electrical signal, and processed by software, so the detection result is obtained.

At the same time, the temperature of the sample can be controlled.

5 types of milk analyzer working principle

1. Chemical Analysis

In the national standard, there are strict regulations on the indicators and testing of milk and other dairy products. The chemical analysis method is the national standard method. The determination of protein in chemical analysis methods often uses the semi-micro Kjeldahl method. The principle of the semi-micro Kjeldahl method is to heat the test sample with sulfuric acid and catalyst to decompose the protein. The decomposed ammonia combines with sulfuric acid to form ammonium sulfate. Then the ammonia is freed by alkalization distillation, and then absorbed by boric acid. Titrate with a standard hydrochloric acid solution and multiply the conversion factor according to the consumption of acid to obtain the protein content. This method requires that the difference between the two parallel determination results of the same sample should not exceed 1.5% of the average value; for lactose, high pressure liquid chromatography and the Rein-Enon method are used, and the difference between the two parallel determination results should not exceed 5% of the average value.

The chemical method is quite mature and can obtain high accuracy, but it takes a long time to get the result and cannot meet the needs of online measurement and analysis.

2. Mid-infrared spectroscopy

The mid-infrared spectroscopy analysis method is relatively mature, and almost impeccable analytical instruments have already come out. The Milk Scan series of rapid milk composition analyzers produced by the Danish FOSS company is one of them. The mid-infrared spectroscopy method uses the absorption of various components in milk to different wavelengths, and completes the determination of milk components by measuring the absorption coefficient and scattering coefficient. FOSS Milk 133 is an early product of FOSS, using interference filter technology, and its prediction accuracy CV value can reach the level of 5%. The FOSS Milk Scan FT120 milk analyzer, using Fourier technology, has a prediction value of 1% for fat, protein and lactose, and a prediction value of 0.8% for non-fat milk solids and total dry matter.

However, the mid-infrared spectrum analyzer is expensive, large in size, and complicated in operation and maintenance, and is not suitable for on-site operation and flow detection.

3. Ultraviolet absorption spectroscopy

The protein content in milk can also be determined by ultraviolet spectroscopy. The principle of determination is that the aromatic ring residues of the protein and its degradation products in the milk can selectively absorb light of a certain wavelength in the ultraviolet region, and within a certain concentration range, light absorption has a linear relationship with the protein concentration, so by measuring the absorbance of the protein solution, the protein content can be measured.

Ultraviolet absorption spectroscopy has the advantages of fastness, simplicity, high sensitivity, and re-linearity. However, because non-protein substances may also cause light absorption in the ultraviolet part, and the interference of light scattering, there is low analysis accuracy.

4. Near infrared spectroscopy

Near-infrared spectroscopy analysis technology uses spectroscopy to analyze the composition and structure of substances. It has the advantages of fast, low cost, no damage to the chemical properties of the sample, and environmental protection. In recent years, it has been used in the field of analysis and testing, especially in the field of online analysis and industrial control. In the fields of agriculture, food industry, petroleum industry, pharmaceutical industry and clinical medicine, near-infrared spectroscopy technology has been successfully applied. The conventional analysis of near-infrared spectroscopy is similar to ultraviolet-visible spectroscopy, which is divided into transmission spectrum and diffuse reflectance spectrum.

In practice, different analysis techniques are used according to different sample properties. The absorption of different components of milk at different wavelengths is often used to establish multiple linear regression models. For example, fat has strong absorption peaks at 1212nm, 1392nm, 1729nm, 1763nm and 2144nm.

In the diffuse reflection test, protein has quite abundant absorption peaks at 1460nm~1570nm, 2050nm~2070nm and 2180nm. In China, some research institutes measured the diffuse reflectance spectrum of milk powder on the model 8620 milk powder analyzer of Pertone, and used 55 high-calcium milk powder samples to establish a model using multiple linear regression algorithms. The correlate coefficient of protein modeling is 0.96 and SEC is 0.196%.

At present, many foreign companies have developed milk powder analyzers based on near-infrared spectroscopy. However, due to the lack of representative models, the measurement accuracy of these products is not satisfactory. This is also a problem that the near-infrared spectroscopy needs to solve.

5. Ultrasonic testing methods

Ultrasonic detection technology uses the interaction between high-frequency waves and substances to obtain the physical and chemical properties of the measured substance. Ultrasound can be divided into longitudinal wave, transverse wave, surface wave and plate wave according to its wave type. In liquids such as milk, there can only be longitudinal waves, while the other three do not exist.

When ultrasonic waves pass through a medium, there are roughly three forms: compression waves, surface waves and shear waves. In the application, compared with the other two forms, the compression wave is the most important, which is the propagation form of the longitudinal wave. The transmission of compression waves in the medium is carried out through the compression and expansion of the medium; but the oscillation of this medium particle with the original position as the origin under the action of the sound wave still obeys Hooke's law, that is, the structure of the medium has no fundamental damage occurred during the transmission of sound waves.

Among the various components of milk, fat and other macromolecular substances have a greater impact on the attenuation of ultrasound, while protein and lactose have a greater impact on the speed of ultrasound. The components in milk can be divided into fat and non-fat milk solids. According to the contribution of the two major components to the ultrasonic attenuation and velocity, a model can be established to measure the percentage of each component, and based on the statistical relationship, the content of other components can be calculated. In this way, the percentages of various ingredients can be obtained. In recent years, great progress has been made in the field of ultrasonic milk composition measurement at home and abroad. The prediction accuracy can reach 5%, which can basically meet the requirements of online measurement and flow detection.

Ultrasonic measurement methods have many advantages over the optical methods mentioned above. The ultrasonic method has low requirements for the measurement environment, so the ultrasonic analyzer is very suitable for flow detection. Compared with optical devices, the ultrasonic probe has a lower price, which makes the cost of the ultrasonic milk composition analyzer lower, which is very suitable for small users. Coupled with the small amount of sample required for analysis, the instrument can be made small in volume and suitable for portable use.

Note: This article takes the ultrasonic milk detector as the main object of description.
