Abstract

The invention belongs to the technical field of milk products, and specifically relates to a preparation method of milk powder for infants. According to the milk powder for the infants, cow milk is used in replacement of breast milk. The cow milk mainly contains casein, beta-casein and [alpha]<s>-casein while the breast milk mainly contains beta-casein and no [alpha]<s>-casein; however, the cow milk is difficult for the infants to digest and absorb due to the [alpha]<s>-casein. And thus, pretreatment is performed on skimmed cow milk. The [alpha]<s>-casein comprises phosphoserine groups, so that, the [alpha]<s>-casein carries net negative charges under alkaline conditions; and thus, the [alpha]<s>-casein has high affinity for calcium ions, and is more likely to precipitate. And therefore, the content of [alpha]<s>-casein in the pretreated cow milk is further reduced so as to make the cow milk easier to digest and absorb; moreover, casein in the cow milk is modified by enzymes extractedfrom egg white so that amido bonds formed by carboxyl of hydrophobic amino acids are primarily catalyzed, and thus, peptide bonds in protein molecules are hydrolyzed so as to produce polypeptides withrelatively small molecular weight. In addition, the prepared milk powder for the infants has certain disease-preventing and disease-resisting functions; and thus, allergenicity of cow milk protein isreduced while safety of the milk powder for the infants is improved.

Description

technical field [0001] The invention belongs to the technical field of dairy products, and in particular relates to a method for preparing infant milk powder. Background technique [0002] Breast milk is the most ideal natural food for infants. The rich nutrients in breast milk provide energy and nutritional needs for the growth and development of infants and young children. However, for those who have insufficient breast milk or are unable to breastfeed due to their own or external factors, infant formula milk powder has become the main breast milk supplement or breast milk substitute in the early stages of infant growth. [0003] Infant formula milk powder is a kind of infant formula food prepared by adding food nutritional fortifiers according to the growth needs of infants of different ages and according to the relevant national regulations. Therefore, the development of infant formula milk powder is based on breast milk. On the basis of cow's milk, the composition and ...
