Abstract
The aims of this study are to report on the extraction and characterization of Asian swamp eel (Monopterus albus) skin gelatin. The characterization conducted were includes chemical composition pH gel strength viscosity thermal property color and structure determination of extracted eel skin gelatin. Eel skin contains 70.28 moisture 11.07 protein 4.21 fat and 5.01 ash. The chemical composition of eel skin gelatin (yield of 12.75) was 18.8 moisture 67.64 protein 0.34 fat and 1.08 ash with a pH of 4.62 and gel strength of 215.96 g ( 9.62 g). Although viscosity (2.8 cPa/min) profile of eel skin gelatin showed lower than that of bovine gelatin the higher melting temperature (35 C) of eel skin gelatin indicating its higher stability than bovine gelatin with FTIR spectrum similar to that of typical bovine gelatin. Eel skin gelatin has a 71.4 ( 1.14) a 3.2 ( 0.29) and a 7.52 ( 0.29) for L a and b value respectively indicate a darker and less yellow colour. These findings show promising potential for the application of eel skin gelatin as an alternative to commercial gelatin.
