Method for preparing albumin hydrolysates

Abstract

In a method for preparing albumin hydrolysates from a starting material containing albumins in concentrated or isolated form, the starting material are homogenized with an aqueous solution at a temperature of between 10 and 80° C. and at a pH of between 8 and 12 in the presence of a first protease for the enzymatic hydrolysis of the albumins. At least one further protease whose cleaving spectrum differs from that of the first protease is added after between 1 and 60 min. from the start of homogenization for the further enzymatic hydrolysis of the albumins. The proteases are inactivated by a heat treatment at a pH below 7.5 within between 1 and 60 minutes from addition of the last protease. The non-hydrolyzed albumins are precipitated at a pH below 7.5. The precipitated non-hydrolyzed albumins are separated from the albumin hydrolysates contained in the solution; and the albumin hydrolysates contained in the solution are concentrated.
