Gelatine properties made from skin and bone of Lizard fish (Saurida tumbil)

Type-A gelatine was extracted from skins and bones of lizard fish and analysed for functional and chemical properties. Bloom gel strength was 159.14±14 and 135±7.9g, respectively, for skin and bone gelatines compared to 2243±7.7 for porcine gelatine (P<0.05). Gelatine from skin and bone exhibited higher viscosity and lower setting temperature than porcine gelatine. Skin gelatine had higher amino acid composition than bone gelatine, with a total amino acid content of about 21.71% and 19.83% for skin and bone respectively. Alpha chains were higher than pi and 6 components in skin and bone gelatine. Both bone and skin gelatines contained peptides with low molecular weight (
