The current study investigates the effect of gamma radiation (0, 1, 3, 5, 7 kGy) and vacuum packaging on shelf-life of silver carp surimi stored at 4 ºC based on variations in pH, peroxide value (PV), thiobarbituric acid (TBA), total volatile nitrogen bases (TVB-N), free fatty acids (FFA), colorimetric parameters (L*, a*, b*), total viable bacterial count (TVC) and textural profile analysis during 15 days. The results indicated that pH did not change with gamma radiation (P> 0.05). Results of oxidative index showed that PV and TBA in surimi reduced significantly with an increase in gamma radiation (P< 0.05) while their increased by increasing the storage time. Irradiation and the storage time significantly increased TVB-N content (P< 0.05). The increase the radiation dose (up to 7 kGy) and the storage time (up to 15 days) had a significant increasing effect on FFA in refrigerated surimi.
