Abstract:

The effect of frozen storage on actomyosin of pike eel muscle was firstly investigated by using differential scanning calorimetry (DSC) and Fourier transform infrared (FT-IR) spectrometer. The results indicated that the increase of storage time results in aggregation and denaturation of actomyosin. At the same time, the surface hydrophobicity increases, while Ca2+-ATPase activity, sulfhydryls (SHs) and salt soluble protein content decrease. Therefore more attention should be paid to frozen storage time to improve processing quality of fish products.

Key words: pike eel, frozen storage, actomyosin
