Description
Technical field
The present invention relates to a kind of baby formula milk powder and preparation method thereof, particularly relate to seed amino acid breast milk baby formula milk powder and preparation method thereof.
Background technology
Breast milk is that baby grows up and grows the most natural, the safest, most complete natural food.But due to various cause specific, in current global range, the baby at Pure breast feeding to 4 monthly age is less than 35%.Baby formula milk powder becomes without breast milk or the optimal substitute food product of the not enough baby of breast milk, the food absolutely not in general sense of formula milk now, but the important nutrient source maintaining infants growth and development and quality of life.
Protein is the important nutrient in breast milk, and the nutriment in breast milk why can efficient absorption, this is easy to digest with breast milk proteins absorb inseparable.For kidney and digestive system still immature baby, the protein that Excess free enthalpy absorptivity is low does not only have benefit, and may cause burden to kidney.Therefore, the high-quality protein of efficient absorption is most important to infants growth and development, and the quality of lactoprotein forms closely related with amino acid wherein.Lactoprotein take in after become various base unit through enzyme hydrolysis in vivo--amino acid, this just human body to one of primary demand of protein.Breast milk is as the ultimate food of the most applicable baby, and the amino acid configuration (i.e. Amino acid profile ratio and content) of its equilibrium is that baby absorbs optimal pattern.The amino acid composition of breast milk is neonate, the particularly key factor of premature neonate nutrient absorption, and therefore for the amino acid configuration of breast milk substitute, particularly required and semi-dispensable amino acid, pressing close to breast milk amino acid composition can effectively improve protein adsorption rate.
At present, high-quality protein mainly contains protein hydrolysate, alpha lactalbumin, CPP etc.Protein hydrolysate is by hydrolysis technology, intact proteins is hydrolyzed into Small molecular peptide chain, and by rejecting stodgy protein part, the amino acid ratio of acquisition forms more rationally, the protein peptide section more easily digested and assimilated.Alpha lactalbumin is a kind of protein merited attention, and is the fabulous source of essential amino acid and branched-chain amino acid, is also the whey protein fraction that uniquely can be combined with metallic element and calcium constituent.In addition, alpha lactalbumin is in amino acid ratio configuration aspects, and it is all closely similar with human milk on functional characteristic, the alpha lactalbumin content that clinical studies show improves newborn Dai Pinzhong can improve the absorptivity to protein of baby, effectively can promote infants growth and development, the tryptophan be wherein rich in has remarkable result to raising infantal sleeping quality.CPP (CPP) take bovine casein as raw material, by the bioactive polypeptide of tool that biotechnology is obtained.CPP molecule is made up of 20 to thirties amino acid residues, comprising the phosphoric acid silk acyl group that 4 ~ 7 clusters exist.Lot of experiments proves, CPP can promote that human body is to the absorption of the divalent mineral nutrients such as calcium, iron, zinc and utilization effectively.
Along with wet nurse more and more payes attention to for infant's Dietary Quality, the nutrient formation of breast Dai Pin there has also been very large development, although babies ' formula milk powder lactalbumin and the casein ratio of current domestic use all reach 60:40, less to the research and apply of amino acid composition and absorbing proteins aspect.
