| description | Optimization of enzymatic hydrolysis conditions of angelwing clam (Pholas orientalis) meat (ACM) catalysed by Alcalase®
to obtain the maximum degree of hydrolysis (DH) was carried out using Response Surface Methodology (RSM). A three
level face-centered central composite design (CCD) was employed. Four independent variables of enzymatic hydrolysis
conditions were applied, which were pH (6.5–8.5), temperature (55–65°C), hydrolysis time (30–120 min), and Alcalase® to
substrate concentration (0.5–2.5%). The optimum condition was obtained at pH of 7.34, the temperature of 64.1°C, hydrolysis
time of 104.2 min and Alcalase® to substrate concentration of 1.65%. It was found that the quadratic model can be used to
describe the relationship between enzymatic hydrolysis conditions of ACM with DH. Verification of the model showed that
at optimum condition, the predicted DH value (99.47%) was close to the experimental DH value (98.75%) (p>0.05). Lyophilized
ACM hydrolysate produced under optimum condition composed of 5.76±0.17% moisture, 65.09±1.09% protein, 1.65±0.06%
fat, 19.95±0.49 ash%, and 7.56±0.80% carbohydrate. This study showed that the degree of hydrolysis of the enzymatic
hydrolysis of ACM catalysed by Alcalase® could be predicted using RSM. |
