The yield of gelatin from the swim bladders was 13.5% (w/w). The amino acid profile of the gelatin revealed a high proportion of glycine and imino acid residues. SDS-PAGE pattern of the gelatin revealed two major bands corresponding to a a-chain and cross-linked component (b-chain). The Bloom strength of solidified gelatin was 264.6 g. The gelling and the melting temperature of gelatin were 13.7 C and 23.3 C respectively as determined by Controlled Stress Rheometer.
