Abstract

In order to improve the quality of sliver carp surimi, the effects of curdlan with different concentrations (0~10 g/kg) on the gel properties of surimi after sterilization at 120 ℃ for 10 min were investigated. Rheological measurement, breaking force, deforma-tion, gel strength, cohesiveness, chewiness, color, water-holding capacity (WHC), TCA-soluble peptide content and SDS-PAGE electrophoresis of obtained curdlan-surimi gel were determined as the quality indexes for evaluating the rheological properties, textural properties, color, WHC and protein composition of surimi. The results showed that addition of curdlan could increase rheological properties and significantly reduced the content of TCA-soluble peptide (P<0.05), thereby improving thermal stability and water-holding capacity of surimi. Curdlan had no effect on surimi protein composition and could decrease the whiteness. The optimized content of curdlan was 6 g/kg, which had positive effect of the gel quality and could significantly improve gel strength and rheological properties (P<0.05).
