Gelatins from the skin of four different species of fresh water fish, namely pangas catfish (Pangasius pangasius), Asian redtail catfish (Hemibagrus nemurus), striped snakehead (Channa Striata), and Nile tilapia (Oreochromis niloticus) have been successfully extracted by citric acid. The gelatin from pangas catfish was found to possessed the highest rheology properties compared to the others. It had the following properties: gel strength of 273.58 g, viscosity of 36.5 cP, melting point at 32oC… Expand

Gelatins from three cultured freshwater fish skins obtained by liming process
TLDR
The physico-chemical properties of gelatins from the skins of Red tilapia, Walking catfish and Striped catfish obtained through a liming process for 14 days had very mild to undetectable fishy odour and had acceptable colour attributes, which were light yellowish to whitish. Expand
Extraction and characterization of gelatin from different marine fish species in Malaysia
TLDR
Results characterization showed that the fish gelatins were comparable to the fishgelatins from other fish species previously reported, and the gelatines derived from "jenahak", "kembung" and "kerisi" had the strongest fishy odor. Expand
