Each protein and the enzyme solution were incubated at 45 degrees C for "0" 15 and 30 min and 1, 2, 3, 4 and 5 h. After that, hydrolysis of the proteins was evaluated by urea-PAGE electrophoresis and densitometry. It was found that the enzymatic degradation of alpha(s1)-casein occured much faster and it was more complete (P<0.01) than degradation of beta-casein. No degradation of whey proteins was found during 5 h incubation.eninfo:eu-repo/semantics/closedAccessArticle133Q4Q3267275WOS:000086223000005
