ND Not Determinate, USP Undigested sardinelle protein
Sardinelle protein hydrolysates were obtained by treatment with crude enzyme preparations from B. pumilus A1 (SPHA1), B. mojavensis A21 (SPHA21) and crude enzyme extract from sardinelle (S. aurita) viscera (SPHEE).
Significantly differences between hydrolysates: *P < 0.05; **P < 0.01; *** P < 0.001
