WHEY PROTEIN HYDROLYSATES AND PEPTIDE FRACTIONS DERIVED FROM WHEY PROTEIN WITH A BIOACTIVE ACTION, OBTAINED BY HYDROLYSIS WITH PROTEASES

摘要

The invention relates to a novel whey protein hydrolysate, which can be obtained by: (i) production of a whey protein suspension with a dry substance content of between 0.1 and 20 %, (ii) establishment of a pH value of between 3 and 9 and a temperature of between 5 and 70 °C in the suspension, (iii) addition of proteases with endo- and/or exo-activity or a combination of activity in a concentration of between 0.1 and 10 %, related to the protein dry mass, (iv) enzymatic hydrolysis to a hydrolysis degree of between 1 and 30 %, (v) deactivation of the proteases and (vi) spray- or freeze-drying of the whey protein hydrolysate suspension, whereby the addition in step (iii) optionally takes place in stages.
