Heat-induced proteolysis of casein micelle suspensions in salt solution, in milk ultra"ltrate and in milk during sterilization (1203C; 10}20 and 30 min) was studied. The increase in the non-protein nitrogen content and the amount of the released peptides soluble in 12% trichloroacetic acid with heating times indicated proteolysis. The low molar mass peptides were identi"ed from HPLC/MS/MS analyses. Ten peptides were characterized, of which three came from i-casein, two from b-casein and "ve from a41 -casein. No major in#uence of the dispersing phase on the heat-induced proteolysis was detected.
