Abstract: The effect of different storage temperatures on the properties of actomyosin of crisped grass carp muscle was studied. The solubility of myofibrils, the activity of Ca2+-ATPase, T-SH content and A-SH content in crisped grass carp revealed an obvious decrease, while surface hydrophobicity (SoANS) increased with prolonged storage time. However, specific properties of protein were greatly influenced by storage temperature. Higher storage temperature resulted in decreased Ca2+-ATPase activity and T-SH and A-SH contents, and increased surface hydrophobicity.

Key words: crisped grass crap, actomyosin, Ca2+-ATPase, hydrophobicity, -SH
