Figure 2.

Specific activity (U. mg/protein) of trypsin in Rainbow trout wastes in different times after blanching (0 and 6 hr). Time 0 means trypsin activity measured from blanched viscera, and time 6 represents evaluated trypsin activity from blanched viscera after six hours of room temperature storage. Capital letters indicate statistical differences between blanching methods in every time point, and small letters indicate statistical differences in trypsin activity in two times (0 and 6 hr) (p < .05) Values are shown as means ± SD
