Abstract: The physicochemical changes of fish muscle protein such as the content of salt extractable protein,ATPase activity,the content of reac tive and total -SH group,the content of -SS bond,surface hy-drophobic activity and viscosity du ring frozen storage were introduced in detail.The effect of some factors like freshness of fish meat,pH value,bleaching conditions,freezing an d thawing conditions on these changes were also introduced.The denaturing mechanism of fish muscle pr otein was analyzed.

Key words: frozen surimi, denaturation, physicochemical changes, affecting factors
