. For thesamples treated at 400 and 600 MPa, lesser amounts of β-LG wereobserved in the emptied digesta, and β-LG band had almost disappearedat 80 min; this was due to hydrolysis by pepsin. In contrast, α-LA washydrolyzed by pepsin earlier in the untreated skim milk and the sampletreated at 200 MPa than in the milks treated at 400 and 600 MPa.
