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 -lactoglobulin, followed by enzymatic hydrolysis with a protease to prepare casein and -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.

The present invention relates to a nutritional formulation containing a pea protein isolate, characterized in that the pea protein isolate: contains between 0.5 and 2% of free amino acids, has a viscosity: from 13 to 1610.sup.3 Pa.Math.s. at a shear rate of 10 s.sup.1, from 10 to 1410.sup.3 Pa.Math.s. at shear rate of 40 s.sup.1, and from 9.8 to 1410.sup.3 Pa.Math.s. at a shear rate of 600 s.sup.1, has a solubility: from 30 to 40% in pH zones from 4 to 5 from 40 to 70% In pH zones from 6 to 8.

The invention also relates to the use of this nutritional formulation as a single protein source or as a food supplement, intended for infants, children and/or adults.

Described herein are antioxidant peptides and methods of producing the same. The antioxidant peptides are produced from cereal grain protein sources, which provide a number of advantages over more expensive antioxidant sources and synthetically-produced antioxidants. The antioxidant peptides are produced by reacting the cereal grain material with an enzyme capable of hydrolyzing proteins within the material, thereby forming hydrolysate peptides. The hydrolysate peptides are then selectively recovered to form an antioxidant peptide product. The antioxidant peptide product is useful in a number of applications, particularly as an ingredient in a food product to provide antioxidant properties to the food product.

The present disclosure generally provides pediatric nutritional compositions comprising a protein source comprising an intact milk protein and a partially hydrolyzed milk protein, wherein about 5% to about 25% of total nitrogen content of the composition is non-protein nitrogen. The pediatric nutritional compositions described herein also comprise a fat source and a carbohydrate source. The partially hydrolyzed protein source, in certain embodiments, provides peptides that have similar structure and function to the peptides found in human milk.
