Summary

The action of gastric proteinases on bovine caseins was studied in vivo on rats fed skim-milk, or whole casein in water or whole casein in mineral solution, by analysing the gastric content after 30 min digestion. Clotting of the diet in the stomach greatly reduced the rate of gastric emptying. The proteolysis of caseins observed by gel electrophoresis appeared to follow a different pathway for the 3 different diets. The amino acid compositions of the trichloracetic acid sediments of the stomach contents did not differ between the 3 diets. The presence of free amino acids in the stomachs at significant levels (0·8–5 % of the total amino acid content) was observed.
