Abstract
In this study, antioxidant and surface-active properties of gelatin hydrolysates (GH) were evaluated. Gelatin obtained from croaker fish (Johnius dussumieri) skin was hydrolysed by the application of visceral proteases extracted from gastrointestinal (GI) tract of two freshwater fish species rohu (Labeo rohita)and catla (Catla catla). The resultant GH was designated as ‘gelatin hydrolysate-rohu protease’ (GH-RP) and ‘gelatin hydrolysate-catla protease’ (GH-CP). Surface-active properties (foaming and emulsion) of GH-RP were significantly higher than GH-CP at concentrations studied (P 10 kDa, 5-10 kDa, 3-5 kDa, 1-3 kDa and 50 value of DPPH radical scavenging activity of fraction 1-3 kDa from GH-RP and fraction
期刊介绍：
The journal (IAR) is an international journal that publishes original research articles, short communications, and review articles in a broad range of areas relevant to all aspects of aquatic sciences (freshwater and marine). The Journal specifically strives to increase the knowledge of most aspects of applied researches in both cultivated and wild aquatic animals in the world. The journal is fully sponsored, which means it is free of charge for authors. The journal operates a single-blind peer review process. The main research areas in aquatic sciences include: -Aquaculture- Ecology- Food science and technology- Molecular biology- Nutrition- Physiology- Water quality- Climate Change
