Abstract
Abstract A total enzymatic hydrolysate from whey proteins is disclosed comprising peptidic hydrolysate with substantially no residual proteins, at least 50% of the peptides containing 2 to 5 amino acids. 70 to 90% of the nitrogen present as peptides has a number of amino acids less than 10. A process for obtaining the total enyzmatic hydrolysate is disclosed comprising hydrolysis of whey proteins with proteolytic enzyme (e.g. pancreatin), which is continued until there is no precipitable nitrogen with 12% trichloroacetic acid. Enzymatic hydrolysis may be carried out continuously. The total enzymatic hydrolysate has uses as food supplement, diet food or intensive care food, and in therapeutic nutrition.
