A whey protein hydrolysate is described which is free of allergenics while preserving the structures susceptible of exerting anticipatory regulations to maximize the tolerance and protein metabolism, and mixtures thereof with casein and/or soy protein hydrolysates. Whey protein hydrolysates according to the invention have an amino acid composition comprising at least 2% by weight of tryptophan, less than 5% by weight of threonine, less than 2.8% by weight of methionine whereby 40 to 60% by weight of the amino acids are in the form of tetra- to decapeptides.

[ We claim:] [1.] A protein hydrolysate comprising a whey protein hydrolysate obtainable by subjecting a whey protein fraction which is substantially free of proteins having a molecular weight of more than 60,000 to the process comprising the steps of:(a) heating a solution of said whey protein fraction in water to 43.degree..+-.4.degree. C. and subjecting said-solution to pepsin prehydrolysis at pH between 2.0 and 3.0;(b) adjusting the pH of the solution of step a) at a temperature in the range of from 35.degree. to 50.degree. to a pH between 7.0 and 9.0 and submitting said solution to an enzymatic trypsin-chymotrypsin hydrolysis in the presence of a cationic serine endoprotease type 2 elastase; and(c) pasteurizing the solution of step b), subjecting said solution to an ultrafiltration, and drying the resulting permeate; admixture with a hydrolysate of casein of which the glycoprotein fraction has been eliminated.
