Application of whey protein in dairy products
1. Application of whey protein in infant formula
The proteins in milk and breast milk mainly include two major categories: casein and whey protein, but the protein composition is different. The amino acid composition of whey protein is closest to that of breast milk and is a protein that is very easy to digest, highly nutritious, and suitable for infants. Whey protein is rich in cysteine and methionine. This sulfur-containing amino acid is very important to the human body. It has an anti-oxidation function and may stabilize DHA during cell division. Whey protein has been shown to promote immune system development. Role.
Whey protein is the main auxiliary material for infant formula. At present, whey protein concentrate WPC34, whey protein WPC70, whey protein concentrate WPC80 are the main applications.
In addition, with the deepening of research, the protein composition of infant formula milk powder is also developing toward the mother emulsification of the hydrogen-acid model. By adding a lactating albumin and hydrolyzing whey protein in the formula, the composition of amino acids in the formula is adjusted to make the product easier. Infant absorption and utilization.
Hydrolyzed whey protein can be used to develop formula for allergic infants. According to the existing guidelines and related clinical studies, the effect of hydrolyzed protein formula on infants and young children is demonstrated. Preferred moderate hydrolysis protein formula for newborns with high risk of allergies; For those who have developed milk protein allergy after birth, deep hydrolysis protein formula or free amino acid formula can be used; Neonatal infants, especially preterm infants, can use different hydrolyzed protein formulations for short-term use, but when applying hydrolyzed protein formulations, pay attention to monitoring the growth and development indicators of children to prevent insufficient nutrient energy intake, resulting in preterm infants. Extrauterine growth retardation, Impact on children’s long-term outcomes
