After the birth of the baby, most mothers have two fears: the baby’s poor immune systems and poor digestion. The digestive system is considered to be the largest immune organ in the body. When digestion is poor, milk nutrients can not be well absorbed and utilized, which naturally affects the development of the baby's immune system. Therefore, it is particularly important to provide nutritious and digestible food for infants and young children. We discussed the choice of milk powder to see the formula.
Of course, the best food for babies is breast milk. Breast milk can provide almost all the nutrients that babies need for growth. Breast-fed babies can digest well and get more immune substances. Well, when breast milk is insufficient or inconvenient, I believe you would like to choose a good digestible milk powder for your baby.
How can we find digestible milk powder? First, you should know some nutrients that are good for digestion or can improve digestion and absorption. Today, the nutritional ingredients introduced to you may not appear in a milk powder at the same time, but after knowing them, you can have a definite aim when choosing milk powder for babies, so that you can find the formula you want. Let's see what there are.
Proteins are important substances for the growth and development of baby's cell tissues, bones, and organs, and are the material basis of life. When choosing milk powder, we should first pay attention to the digestion and utilization of protein.
Whey protein is a kind of high-quality protein with the highest nutritional value. Its main components are alpha-lactalbumin, beta-lactoglobulin, immunoglobulin, and lactoferrin. It is known as the "King of Protein". It is rich in eight essential amino acids needed by the human body. It has a reasonable proportion and high digestion and absorption rate. It is very in line with human needs. About 70% of breast milk protein is whey protein. Breast-fed babies have soft and fewer amount stools, less vomit and diarrhea and constipation.
Fat is one of the most important energy substances in the human body. It maintains the development and normal function of the baby's brain, cardio-cerebrovascular tissue, and vision. If fat digestion and absorption are not good, not only affect the development but also may lead to diarrhea, constipation symptoms and other digestive abnormalities. In formula milk powder, adding the following fat is better for digestion.
Because there are less unsaturated fatty acids in milk for babies, people also adjust the structure of the fat. Some unsaturated fatty acids in animal milk are removed. Vegetable oils containing more unsaturated fatty acids are selected to adjust the proportion of fat in formula milk powder, which can meet the needs of babies. The digestive absorption rate of fat is higher. The commonly used vegetable oils are walnut oil, peanut oil, rapeseed oil, soybean oil, sunflower seed oil, coconut oil, corn oil, etc. Some contain palm oil, but palm oil is easy to combine with calcium and cause constipation. More and more milk powder is replaced by OPO structural fat.
OPO structural grease.
This is an unsaturated fatty acid with a structure very close to breast milk fat. Its scientific name is triglyceride 1, 3-Dioleic acid, and 2-palmitate. Studies show that 98% of the fat in breast milk is triglyceride, 70% of the palmitic acid in triglyceride is linked to the 2nd position, and unsaturated fatty acids are mainly linked to the 1st and 3rd position, namely OPO structural lipids. In order to make formula milk powder contain more OPO structural lipids, the unsaturated fat position on plant palm oil was replaced by enzymatic lipid exchange technology, and the ratio of 2-position palmitic acid was increased by more than 40%.
This fatty acid, which simulates the structure of breast milk fat, can greatly improve the baby's digestive and absorption capacity of fat, soften stool, reduce constipation caused by saponification of calcium ions in the intestine, and improve the utilization rate of calcium to support the development of baby's skeleton. In addition, OPO structural lipids can also help the proliferation of intestinal probiotics, help to balance the intestinal micro ecological balance and maintain intestinal health.
Probiotics are carbohydrates that can be selectively utilized by probiotics in the human body, especially in the intestinal tract. They are generally soluble dietary fibers. They are the nutrient sources for the survival and proliferation of probiotics. Adding milk powder can maintain the balance of normal intestinal flora, inhibit the production of harmful substances or microorganisms, prevent or reduce the occurrence of diarrhea and constipation, and promote calcium absorption. At present, the probiotics used in dairy products are galactooligosaccharide, fructooligosaccharide, fructose-polysaccharide, raffinose, polydextrose and so on.
Galactooligosaccharides are abundant in breast milk. The establishment of bifidobacterial flora in the intestine of babies after birth depends largely on GOS in breast milk. It has strong acid and heat resistance, and will not lose its proper characteristics due to high-temperature sterilization or gastric acid decomposition during processing. Its stability is better than fructooligosaccharide. Galactooligosaccharides are the only probiotics that can be used by 8 common probiotics in the intestinal tract. They are also an important component of breast milk. Therefore, galactooligosaccharides are most commonly used in formula milk powder, sometimes in combination with fructooligosaccharides.
Fructooligosaccharides are mainly made from Jerusalem artichoke powder, which has a selective proliferation of Bifidobacterium and Lactobacillus. It can reduce and inhibit the production of intestinal putrefaction substances, inhibit the growth of harmful bacteria types, regulate intestinal balance, and promote the absorption and utilization of trace elements iron and calcium. Galactooligosaccharide is often used in infant formula milk powder.
Cottonseed sugar mainly exists in plants, such as beet, potatoes, cabbage, soybeans, grapes, bananas and so on. It also has a proliferation of bifidobacteria and lactic acid bacteria. In 2012, raffinose was allowed to be used in food, health products, and cosmetics. At present, a small proportion of infant formula milk powder has been added raffinose.
Fructopolysaccharide extracted from chicory root is a good "probiotics", which can regulate intestinal flora, proliferate bifidobacteria and promote calcium absorption.
A D-glucose polymer was prepared from glucose, sorbitol, and citric acid. In food, additives can be used as thickeners, fillers, formulations. It has the function of keeping intestine and stomach unblocked and reducing constipation. It is conducive to the reproduction of intestinal bifidobacteria and lactobacillus and inhibits the reproduction of harmful bacteria such as Clostridium and Bacteroides. At present, it is seldom used in milk powder, but it is common in probiotic products and other health foods.
Probiotic infant formula milk powder can be added to animal bifidobacteria, Lactobacillus, Lactobacillus Rhamnosus, Lactobacillus Roy, Lactobacillus Fermentans, Bifidobacterium Brevis, and other six probiotics. These probiotics have strong acid and heat resistance, and can better reach the intestinal tract and colonize. The minimum viable bacteria in formula milk powder should be 106 CFU/100g. This paper mainly introduces several probiotic strains of Bacteria List for Infant Food issued by the State Health Planning Commission (Announcement No. 6 of 2016).
Animal Bifidobacterium Bb-12
Animal Bifidobacterium Bb-12 is the most important physiological bacteria in human and animal intestines. It can colonize rapidly in the intestine and has a high content in the infant's intestine. It can synthesize essential amino acids of vitamin B1, B2, B6 and K, alanine, aspartic acid and threonine for human absorption and utilization. Food can be degraded to improve the digestive absorption of food. Animal bifidobacteria can decompose lactose into glucose and galactose in milk powder to alleviate lactose intolerance in babies. Bb-12 is an animal Bifidobacterium Lactobifidus subspecies. It has high stability in food, excellent acid and bile resistance, strong intestinal adhesion, and is also the first probiotic bacteria allowed to be used in infant formula milk powder.
It is a subspecies of animal bifidobacterium. It is similar to animal Bifidobacterium in improving infant digestion. Bifidobacterium Lactis can effectively shorten the intestinal transit time and is superior to common probiotics in improving the digestive capacity of babies. In addition, these probiotics can improve cellular immunity by increasing the phagocytic capacity of neutrophils, which is very good for enhancing the immunity of babies.
Lactobacillus Rhamnosus LGG/HN001.
Lactobacillus Rhamnosus belongs to the Lactobacillus genus and is a probiotic bacteria isolated from the human healthy intestine. It has strong stomach acid resistance, high intestinal adhesion rate, and strong colonization ability. It plays a role in regulating intestinal flora, preventing and alleviating diarrhea and constipation, and improving immune system function. Lactobacillus Rhamnosus can promote the growth of Bifidobacterium and Lactobacillus acidophilus, and milk allergic constitution. However, Lactobacillus Rhamnosus can not use lactose, which has a general effect on alleviating lactose intolerance.
Lactobacillus Roy DSM17938
Lactobacillus Roy DSM17938, a genus of Lactobacillus, is widely distributed in the intestines of vertebrates and mammals. It can improve the allergic constitution, prevent repeated allergies, promote gastric emptying in infants, reduce vomiting and regulate gastrointestinal function.
Lactobacillus Fermentans CECT5716
It belongs to the Lactobacillus genus. It is a specific strain screened from human milk. It can improve the immunity and intestinal health of mothers and babies at the same time. The addition of milk powder can reduce infant gastrointestinal and respiratory tract infections.
Bifidobacterium breve M-16V
It belongs to the genus Bifidobacterium. It is isolated from healthy infant intestine and is one of the main beneficial bacteria in the infant's intestine. In addition to improving the digestive and absorptive capacity of infants, Bifidobacterium Brevis M-16V is effective in preventing necrotizing enterocolitis of premature infants and has certain effects on allergic asthma, allergic dermatitis, and eczema. Although the proportion of sugar in milk powder is between 55% and 60%, it is better to digest. Probiotics in this article can also help babies absorb sugar, so it is not the topic of this discussion. If you want to find a digested milk powder, you can choose the above nutritional facts. It should be noted that protein and fat are the major components of milk powder. We must first pay attention to these two components, such as the proportion of whey protein and the structure of fat, and then other components.
