To prepare a hypoallergenic whey protein hydrolyzate product, particularly for employment in infant formula, whey material first is hydrolyzed with a proteolytic enzyme and then the enzymatic hydrolyzate is subjected to a heat treatment to denature proteins which remain intact after the first hydrolysis and which constitute allergens, and then the heated hydrolyzate is cooled. The cooled heat-treated hydrolyzate then is hydrolyzed by a proteolytic enzyme to provide a hydrolyzate substantially free of allergens of protean origin.

A process for the preparation of a hypoallergenic whey material based product comprising: hydrolyzing a whey material containing whey proteins with enzymes selected from a group of enzymes consisting of trypsin, chymotrypsin and pancreatin to provide a first enzymatic hydrolyzate; heating the first hydrolyzate for from 3 minutes to 10 minutes at a temperature of from 80°C. to 100°C. at a pH of from 6 to 8 to denature proteins remaining intact after the first hydrolysis; cooling the heated first hydrolyzate to a temperature of from 40°C. to 60°C.; subjecting the cooled first hydrolyzate to hydrolysis with enzymes selected from a group of enzymes consisting of trypsin, chymotrypsin, pancreatin and mixtures of trypsin and chymotrypsin to hydrolyze the intact denatured proteins in the first hydrolyzate for providing a second hydrolyzate substantially free of allergens of protein origin; and then heating the second hydrolyzate to thermally inactivate the enzyme for providing a substantially allergen-free hydrolyzate product.
