Study on antioxidation properties of hydrolysates from the scallop skirt in vivo and in vitro

Employing the portamex, the antioxidative hydrolysates were successfully produced by the hydrolysis method under the condition of pH7.5, 50℃ and 3h. The obtained hydrolysates showed high antioxidative ability in vitro, which clearance rate of DPPH radical was 93.14%. The IC50 values of hydrolysates for superoxide anion and DPPH radical were 7.97mg/mL and 2.89mg/mL, respectively. According to the animal experiments, the results showed that the hydrolysates could decrease the content of MDA by 57.4% and increase the activities of CAT and SOD by 20.1% and 4.2%, respectively. As a result, the conclusion can be drawn that the hydrolysates obtained possessed high antioxidative ability both in vivo and in vitro.
