Abstract
ABSTRACT The effect of Alcalase hydrolysis conditions on antioxidant activities of shark skin gelatin hydrolysate (SSGH) byproduct was studied. Optimal hydrolysis condition for SSGH at 60°C, pH 7.5, and 2.70 AU kg−1 gelatin protein was used for varied hydrolysis times (10–90 min). The IC50 against DPPH radicals of SSGH hydrolyzed for 90 min (SSGH-90) was 27.39 mg ml−1, which is greater than ascorbic acid. SSGH-90 was predominantly composed of 15–20 kDa protein fragments that regulated increases in peroxide value and thiobarbituric acid reactive substances values and suppressed decrease in DHA of a fish oil-in-water emulsion during storage at 30°C for 7 days.
