The physico-chemical properties of gelatins from the skins of Red tilapia (Oreochromis nilotica), Walking catfish (Clarias batrachus) and Striped catfish (Pangasius sutchi fowler) obtained through a liming process for 14 days were evaluated. All the gelatins had very mild to undetectable fishy odour and had acceptable colour attributes, which were light yellowish to whitish. The highest gelatin yield (dry basis) was obtained from red tilapia (39.97%) skin and the bloom strength exceeded 300 g… Expand
Extraction and characterization of gelatin from different fresh water fishes as alternative sources of gelatin.
Gelatins from the skin of four different species of fresh water fish, namely pangas catfish, Asian redtail catfish (Hemibagrus nemurus), striped snakehead, and Nile tilapia (Oreochromis niloticus) have been successfully extracted by citric acid. Expand
