Temperature Dependency of Compression Properties of Fish‐meat Gel as Affected by Added Starch

Abstract

ABSTRACT The influence of starch addition on the elastic properties of fish‐meat gel was studied by measuring compression and stress relaxation properties and dynamic viscoelasticity. Samples with pregelatinized starch, with and without raw starch, and processed starch were used. Fish‐meat gels with starch showed a higher modulus value at 80°C than at 90°C. The gelatinization of starch appeared to be prevented by surimi protein in the fish‐meat gel, and so the sample that gelled at 90°C had a lower “packing effect” than the sample that gelled at 80°C. The optimum heating temperature indicated a higher “packing effect” on the surimi protein.
