| abstract |
The application relates to a method for the selective hydrolysis of casein/caseinate in the presence of at least one further protein constituent other than casein/caseinate, the casein/caseinate and the at least one further protein constituent being brought into contact with a proteolytic enzyme under conditions for the hydrolysis of the casein/caseinate, characterized in that the casein/caseinate and preferably also the at least one further protein constituent are in an essentially dissolved state, and in that a proteolytic enzyme is a proteinase specific for casein/caseinate, such that the casein/caseinate is hydrolysed while the further protein constituent remains essentially intact. This method can be used, in particular, for the preparation of a hydrolysed casein preparation or alternatively for the preparation of a milk protein preparation, in particular a whey protein preparation which has been stripped of casein/caseinate. The invention further relates to the preparations thus obtained, which have beneficial properties with respect to allergic reactions to milk proteins, and diabetes. |
