Kit Components
1. Test Strip, 12 packs, each pack 8 strips.
2. Manual Instruction

Components Required, But Not Provided
1. Sample Tube
2. Pipette
3. Well-tray

Storage
Storage at 2~8℃, out of sun light and moisture, unrefrigerated.

Milk Sample Information
1. Raw, commingled cow milk
2. The milk has no precipitation or clotted.
3. The temperature of milk should be at room temperature, No need to heat or refrigerate.
4. Thoroughly mix with the reagent before testing.

Test Procedure
1. Read the manual instruction before testing. Be sure the raw or commingled milk and test kit in room temperature. (Note: the milk must has no precipitation or clot)
2. Open the pack, take out the test strip and sample-well, use it within 1 hour. The unused test strip must be sealed and out of sunlight and moisture.
3. Take the sample milk, let it become room temperature. Drop 200ul into the microwell, repeatedly pipetting up and down for 10 times, mix the with the reagent in the wells completely.
4. Then wait for 5mins.
5. Insert the test strip into the microwell with the end fully dipped.
6. Timer 5 minutes, then read the results.

Trivia questions : What is Formaldehyde？

Formaldehyde definition

Formaldehyde, colorless and irritating gas, chemical formula HCHO or CH₂O, has irritating effects on human eyes and nose. The concentration of the aqueous solution is up to 55%, usually 40%. It is called formaldehyde, and it is commonly known as formalin.

Formaldehyde structure

Formaldehyde is an organic compound because it has a carbon atom in its chemical formula. It is also classified as an aldehyde, which is an organic compound (shown here as RC = OH) that contains a formyl group (red box) and an R group, which is a group containing carbon and / or hydrogen.

Formaldehyde smell

Formaldehyde has an irritating odor and can be smelled at a low concentration. The olfactory threshold of humans for formaldehyde is usually 0.06 to 0.07 mg / m3. But there are large individual differences, some people can reach 2.66mg / m3.

Formaldehyde uses

Formaldehyde embalming

A 35% to 40% formaldehyde aqueous solution is commonly known as formalin. It has antiseptic and antiseptic properties and can be used to soak biological specimens and disinfect seeds. However, it is easy to make specimens brittle due to denaturation of proteins.
The main reason that formaldehyde has antiseptic and antiseptic properties is that formaldehyde can react with amino groups on proteins of organisms (including bacteria).

Formaldehyde in furniture

It is inevitable that furniture and adhesives are used in the manufacturing process. Chemicals such as adhesives and paints generally contain formaldehyde. The formaldehyde in the indoor air mainly comes from the decorative materials and artificial wood boards used in the new combination furniture, such as the adhesives in plywood, large core boards, MDF, and flowerboard (particle board). When exposed to heat and deliquescence, formaldehyde is released from the adhesive.

Formaldehyde in vaccines

Formaldehyde is added to the vaccine to inactivate it. Formaldehyde is a carcinogen with strong irritation. It can act on both the amino acid-containing nucleotide bases of the virus (such as A, G, U) and the virus coat protein. When acting on the shell protein, the protein is easily cross-linked or the virus particles are aggregated, and it can no longer act on the nucleic acid in the shell protein. In this way, the antigenicity of the pathogen protein will be severely damaged, and the pathogen may survive; the inactivation time with formaldehyde is long, and it usually requires treatment at 37-39 ° C for more than 24 hours or longer.

Formaldehyde in food

There are three main sources of formaldehyde in food: "endogenous" production of animals and plants, artificial addition, introduction or contamination during processing.

Formaldehyde is a normal metabolic component in many foods, including fruits, vegetables, livestock and poultry meat, fish, crustaceans, etc. However, most foods have low formaldehyde content and are not harmful to health.

Formaldehyde can be used as a bacteriostatic agent in foods such as cheese. In Australia and the United States, small amounts of formaldehyde are allowed as feed additives in feed

Formaldehyde pollution in the environment can also cause formaldehyde residues in food. For example, the formaldehyde aqueous solution used in the environment to disinfect facilities, tools, environmental disinfectants or three-dimensional space fumigation disinfectants can cause environmental pollution to varying degrees, thereby contaminating food.

Formaldehyde in cosmetics

Most formaldehyde detected in cosmetics is not directly added to the formaldehyde itself, but formaldehyde releasers. It mainly kills microorganisms by slowly releasing a small amount of free formaldehyde in a cosmetic system.

Formaldehyde side effects

Formaldehyde poisoning

Mild poisoning: obvious eye and upper respiratory tract mucosal irritation symptoms. Mainly manifested as conjunctival congestion, redness and swelling, difficulty breathing, heavy breathing sounds, hoarse throat, speech or dry dullness or wetness. The poisoned person can also feel his breathing sound thicker. Another specific manifestation of mild formaldehyde poisoning is throat edema of one to two degrees.
Moderate poisoning: persistent cough, expectoration, chest tightness, dyspnea, and wet and dry gong sounds. On chest X-ray, the texture of the lungs becomes substantial and turns into scattered small spots or flaky shadows, which is a medical model of bronchial pneumonia; throat edema increases to third grade. Blood gas analysis is performed with mild to moderate hypoxemia.
Severe poisoning: The condition of the lungs and throat has deteriorated, and pulmonary edema and fourth-degree larynx edema appear. Blood gas analysis is also severe, and it is severe hypoxemia.

Formaldehyde allergy

Formaldehyde is allergic to the symptoms of skin. Generally, patients will experience itching, congestion, rash, skin damage, etc. In severe cases, purulent necrosis may occur.

Is formaldehyde a carcinogen?

Formaldehyde toxicity

The main harm of formaldehyde is the irritating effect on the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Formaldehyde concentrations greater than 0.08 mg / m³ can cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc. The relatively high formaldehyde content in newly renovated rooms is the main cause of many diseases.
On October 27, 2017, in the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization, formaldehyde was placed in the list of carcinogens. On July 23, 2019, formaldehyde was included in the list of toxic and harmful water pollutants (the first batch).

Summary

China stipulates that the addition and use of formaldehyde in food processing is prohibited, and some manufacturers and traders still illegally add formaldehyde or sodium formaldehyde sulfoxylate to food for profit. Such as flour, aquatic products, etc. Adding formaldehyde to aquatic products can extend the shelf life and increase water holding capacity. Adding formaldehyde or sodium formaldehyde sulfoxylate to foods such as flour and rice flour has a whitening effect.
The Formaldehyde Rapid Test For Milk kit provided by BALLYA can effectively detect whether milk contains formaldehyde and ensure the quality of the tested milk. This kit is easy to operate, with short detection time and high accuracy. The test results comply with EU standards.
