Description

Mother-emulsified infant formula goat milk powder capable of improving immunity and preparation method thereof

Technical Field

The invention belongs to the technical field of food, and relates to infant milk powder, in particular to infant formula goat milk powder for improving immunity and optimizing the composition of amino acid and fatty acid and a preparation method thereof.

Background

Breast milk is a natural food most suitable for infants and is also the gold standard for the design of formula milk powder. For infants, the bioavailability of breast milk is the best, and breast feeding has great advantages in aspects such as nutrition, immunity, physiological and psychological needs and the like. However, not all mothers have enough breast milk to feed babies after the babies live, a large part of newborn babies are fed with the breast milk and the formula milk powder in a mixed mode at present, and even some babies eat the formula milk powder all the time from birth.

Infant formula is the most important breast milk substitute in the modern infant feeding process, and like breast milk, formula also supports the development of the body, immune function and behavior of the newborn by providing nitrogen and essential and semi-essential amino acids. The main raw material of the existing formula milk powder is cow milk or goat milk, but due to the difference among species, the types and the contents of nutrients of animal milk, such as cow milk, goat milk, horse milk, camel milk and the like, and human milk are different. Compared with cow milk, the goat milk has the advantages of higher whey protein content, easier digestion and absorption by human bodies and contribution to improving the problem of cow milk protein allergy of infants, and researches show that the protein and fat structures in the goat milk are more similar to those of the cow milk. Therefore, based on milk source difference, the protein content and the amino acid composition in the infant formula goat milk powder are adjusted and optimized, the protein absorption utilization rate of the infant in the formula goat milk powder is improved, the amino acid ratio mother emulsified formula goat milk powder more suitable for the growth of infants in China is developed, and the improvement of the nutrition absorption and growth development of the infants is facilitated. Therefore, based on the difference of amino acid composition, the amino acid content in the infant formula milk powder is adjusted and optimized, the absorption and utilization rate of the infant to the amino acid in the formula milk powder is improved, the burden of a digestive system is relieved, and the method is an important direction in formula milk powder development.

The current development trend of infant formula milk powder is closer to breast milk, and in order to enable the formula of the infant formula milk powder to be closer to the nutrient content of breast milk, European and American countries gradually determine the dietary reference intake of infants and the formula of infant food according to the breast milk nutrient content data of the countries. While the design ability of the Chinese formula milk powder is slightly behind, most of the formula milk powder refers to foreign research data. However, the foreign infant food formula is not necessarily suitable for our infants in China based on the differences of dietary culture, living environment and self genes of different regions and races. Therefore, the formula milk powder which is more suitable for being eaten by the infants in China in terms of amino acid composition is urgently needed to be developed according to the nutrient component data of the breast milk in China and the physical quality and growth needs of the infants.

EXAMPLE 17 intestinal health Effect of goat milk powder formula on infants

The intestinal flora of infants gradually develops to be stable along with time after birth, an in vitro intestinal flora simulation system is established in the research, and the influence of the formula milk powder on the intestinal flora is researched. Infant intestinal flora models of 6 months and 12 months are respectively established, and 3 groups (a control group, an intervention group and a breast milk group) are respectively set. The control group is added with the traditional formula goat milk powder, the intervention group is added with the formula goat milk powder of the invention in the embodiment 5, the breast milk group is added with breast milk, all the additives are degraded by the compound gastrointestinal digestive enzyme, the samples are collected for 3 months continuously, and the samples are collected every month for microbiological analysis.

Wherein, the intestinal flora of the infant is in the development stage after birth, is influenced by the pregnancy stage, the production mode, the feeding mode and the like, enters the transition stage at 14-15 months, and the diversity of the flora is increased and then tends to be stable. The intestinal tract of infants of 6 months is dominated by bifidobacteria, and the differences of the phylum firmicutes, the phylum actinomycetes, the phylum bacteroidetes and the like are large along with the change of time. In the research, after the prognosis of the intestinal flora model of the infant for 6 months, the intestinal flora among 3 groups has no obvious difference, which shows that the formula milk powder has no obvious influence on the development period with large flora fluctuation. The intestinal flora of the infant of 12 months is at the end of the development period, and gradually changes to the transition period during the intervention period, the abundance of the flora tends to be stable, and the flora difference is small along with the change of time. Therefore, after intervention of 3 months, in a 12-month infant intestinal flora model, as shown in fig. 4, compared with a control group, the flora composition of an intervention group is more similar to that of breast milk, so that the formula milk powder disclosed by the invention does not influence the development of the intestinal flora of infants at low ages, aims to promote the development of the intestinal flora of the infants, accelerates the abundance of the flora to be stable, enables the intestinal flora to be more similar to that of breast milk feeding, is superior to the traditional formula milk powder, and is beneficial to the intestinal health requirements of the infants.
