Antioxidant Activity of Acid Pretreated Gelatin Extracted from Duck Skin By-Products

In this study, we have characterized the acid-pretreated gelatin extracted from duck skin by-products. To this end, we employed two-dimensional gel electrophoresis to validate the size of gelatin (72 kDa) and scanning electron microscopy to examine the surface characteristics of gelatin. We next examined the antioxidant activity of acid-pretreated gelatin extracted from duck skin by three-dimensional imaging using electronic spin resonance. The results show Alkyl, 1,1-diphenyl-2picrylhydrazyl, and hydroxyl radical scavenging capabilities of acid-pretreated gelatin. We hope that these data will help expand the industrial application of duck-skin-derived gelatin.
