Effects of frozen storage of silver carp (Hypophthalmichthys molitrix) on qualitative properties of surimi powder

The effects of frozen storage (-20°C) of silver carp (Hypophthalmichthys molitrix) for periods of 0 (control), 2, 4 and 6 months on the qualitative properties of surimi powder was investigated. Qualitative characteristics were assessed through analysis of proximate composition, sensory evaluation, color changes, density, oil adsorption capacity, water holding capacity, protein solubility, emulsifying capacity, emulsion stability, foam capacity and stability, gel forming ability, and thiobarbituric acid value. Most of the qualitative indices decreased significantly (p
