| Abstract: | - 1.1. The in vitro digestion of soya protein by pancreatic proteases of the trout was measured following various conditions of stomach digestion.
- 2.2. Peptic hydrolysis results in an increase of small peptides.
- 3.3. Acid treatment and peptic proteolysis do not affect the degradation of insoluble proteins or the formation of free amino acids during intestinal digestion, but they do lead to a significant shift from soluble polypeptides to di- and oligopeptides.
