Partial hydrolysate of whey proteins, enzymatic process for the preparation of this hydrolysate, and hypoallergenic dietetic milk food containing it

摘要

The invention relates to biotechnology. It concerns a partial hydrolysate of whey proteins which contains no residual whole proteins characterized in that it contains peptides spread over the following distribution, as a function of their molar mass: - Proportion by weight -Molar mass (as g peptides per -(g per mole) 100 g total peptides) - MM>5000 0-5 - 5000>MM>3500 15-25 - 3500>MM>1500 20-30 -1500>MM>500 35-45 - MM<500 5-10 - as well as the free amino acids; the free amino acid content of the hydrolysate being less than 10% (calculated as grammes of nitrogen per 100 grammes of total nitrogen), as well as an enzymatic product for its preparation: Application to the production of dietetic milk foods.
