Abstract | Full Text

In the present study, hydrolysed protein of viscera and head of Silver carp (Hypophthalmichthys molitrix) was compared using Alcalase enzyme and internal tissue enzymes at 2 and 4 hours. The result indicated that product by Alcalase (Treatment 1) had significantly higher protein and rate of hydrolysates than that produced by internal tissue enzymes (Treatment 2). So, the highest mean (±SD) protein (68.10±1.33) was related to treatment 1-head (with Alcalase enzyme) after 4 hours and the highest rate of hydrolysates (29.36±1.35) was related to treatment 1-head (with Alcalase enzyme) after 4 hours. The result indicated that rate of hydrolysates raised as time of hydrolysates increased. However the intensity and rate of hydrolysates is reduced. The highest rate of hydrolysates occurred at 120 minutes in the first. This mode was similar for two treatments. The result can be considered as the Alcalase was preferred to internal enzyme.
