The present invention relates to a nutritional composition for improving the temperament of young children. The nutritional composition for an infant or toddler comprises a2-β-casein, wherein the a2-13-casein represents more than 50%, preferably, more than 70%, more preferably, more than 90%, even more preferably, 95%, or most preferably 100% of total β-caseins. The composition has been clinically shown to improve the temperament in toddlers and young children.

A polypeptide fragment D (MP-D) has an amino acid sequence shown in SEQ ID NO: 1, in which an amino acid Xaa at position 9 is Tyr, Val, Gly, Ser, Gln, or absent, an amino acid Xaa at position 20 is Ser, Gln, Glu, Tyr, Arg, or absent, and an amino acid Xaa at position 25 is Asn, Thr, Ser, Pro, Leu, or absent. The MP-D can significantly improve the colonic pathologic morphology and decrease a colonic histopathologic score and an expression level of colonic interferon-γ (IFN-γ) in an inflammatory bowel disease (IBD) mouse model, and shows the ability to interfere with the occurrence of IBD in mice.

A polypeptide fragment C (MP-C) has an amino acid sequence shown in SEQ ID NO: 1, in which an amino acid Xaa at position 9 is Tyr, Val, Gly, Ser, or Gln, an amino acid Xaa at position 20 is Ser, Gln, Glu, or Tyr, an amino acid Xaa at position 30 is Asn, Thr, Ser, Pro, or Leu, and an amino acid Xaa at position 42 is Gly, Arg, Met, or absent. The MP-C can significantly improve the colonic pathologic morphology and decrease a disease activity index (DAI) and a colonic histopathologic score in an inflammatory bowel disease (IBD) mouse model, and shows the ability to interfere with the occurrence of IBD in mice.

An ultrasound-assisted simulated digestion method of a milk protein active peptide and an application thereof in health foods, pertaining to the technical field of intensive processing of dairy products and preparation of health foods. The method firstly employs ultrasonic pretreatment of casein and β-lactoglobulin, followed by enzymatic hydrolysis with a protease to prepare casein and ρ-lactoglobulin polypeptide, and traces the activity of the polypeptide by simulating gastrointestinal digestion, and then simulates absorption by intestinal epithelial cells with Caco-2 cells, to characterize a highly active milk protein polypeptide digested by the gastrointestinal tract and absorbed by the Caco-2 cells simulating absorption by the inner wall of the small intestine. The method has identified five such highly active milk protein polypeptides.
