Abstract:This study aimed to identify the properties of gelatin extracted from snakehead fish (Channa striata) by-products, including scale and a mixture of skin and scale. The gelatin extraction yield from fish scales was lower than that from fish skin and scales. Both gelatins showed similar gel strength (248 g in the mixture of fish skin and scale and 245 g in fish scale gelatin), while the viscosity and color of samples from fish skin and scale were better than those of fish scale samples extracted at 80 °C for 1 h… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
