Abstract

Described is the chemical hydrolysis of partial hydrolysates obtained by the enzymatic decomposition, in aqueous conditions in the presence of alkaline-earth oxides or hydroxides, of protein-containing raw materials containing chromium. This enables protein hydrolysates with a particularly low chromium content to be obtained which are stable to turbidity during storage. The chemical hydrolysis must be carried out in the presence of compounds selected from the alkaline-earth oxides and hydroxides, and within the critical pH range of 11 to 13.
