Abstract
The effect of ice-storage duration (0, 3, 6, 9, 12, and 15 days) of silver carp (Hypophthalmichthys molitrix) on qualitative properties of its surimi powder was assessed by analyzing proximate composition, color changes, density, oil adsorption capacity, protein solubility, emulsifying capacity, emulsion stability, gel forming ability, and thiobarbituric acid. Increase in ice-storage duration increased the density and thiobarbituric acid of surimi powder(p<0.05); proximate composition, color indices, protein solubility, oil adsorption and gel forming decreased significantly (p<0.05); emulsifying capacity and emulsion stability decreased with storage duration, although no regular trends were detected (p<0.05). The present study indicated that long-term ice-storage of silver carp led to reduction of qualitative properties of the surimi powder.

Abstract
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<0.05) in the treatments, including the water holding capacity and the percentage of protein solubility that, respectively, decreased from 13.4ml/g and 7.42% in the control to 10.46 ml/g and 4.82% after 6 months of frozen storage. Besides, the treatments didn’t show foam. The density and thiobarbituric acid increased significantly with time (p<0.05). Based on the analyses as well as sensory assessment, quality of silver carp surimi powder was maintained in -20°C frozen storage up to four months.
