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. |
