Whey protein hydrolysate containing tryptophan peptide consisting of alpha lactalbumin and the use thereof |
摘要 |
In a method for producing a whey protein hydrolysate, a whey substrate, selected from the group consisting of whey, commercially available whey powder, whey protein isolate, whey protein preparations, and α-Lactalbumin obtained from whey, is enzymatically hydrolyzing at least with alcalase and trypsin as enzymes at a ratio of g enzymes/g whey substrate between 1:10 and 1:10,000 and at a temperature of between 30° C. and 70° C. within an incubation period of between 18 hours and 30 hours, until a hydrolysis degree of more than 50% of the protein of the whey substrate have a molecular weight of less than 4 kDa. The enzymes are inactivated by heating the enzymes to a temperature of 80° C. to 100° C. after the desired hydrolysis degree has been reached. |

1. A method for producing a whey protein hydrolysate, the method comprising the steps of:
enzymatically hydrolyzing a whey substrate, selected from the group consisting of whey, commercially available whey powder, whey protein isolate, whey protein preparations, and α-Lactalbumin obtained from whey, at least with alcalase and trypsin as enzymes, at a ratio of g enzymes/g whey substrate between 1:10 and 1:10,000 and at a temperature of between 30° C. and 70° C. within an incubation period of between 18 hours and 30 hours, until a hydrolysis degree of more than 50% of the protein of the whey substrate have a molecular weight of less than 4 kDa; inactivating the enzymes by heating the enzymes to a temperature of 80° C. to 100° C. after the desired hydrolysis degree has been reached. |
