Effects of Washing Technique on Gel Strength and Whiteness of Surimi from Silver Carp(Hypophthalmichthys molitrix)

The influence of washing treatments including water washing times,NaCl solution washing times and washing temperature on the gel strength and whiteness of silver carp surimi were investigated.The results showed that the washing treatments using water and NaCl solution could increase the gel strength and whiteness value of silver carp surimi significantly.Silver carp surimi made by washing two times with water and one time with NaCl solution had higher gel strength and whiteness value.Washing temperature had no significant effect on gel strength and whiteness of surimi.However,the washing temperature should be controlled in low-temperature condition in order to keep fish meat fresh.
