Abstract

In order to explore the suitable irradiation range of ⁶⁰Co-γ ray irradiation on Youtazi, which was adopted ⁶⁰Co-γ ray irradiation with different irradiation dose to investigate the effects of irradiation dose on microorganism, acid value (AC), peroxide value (POV) and chromatic aberration of Youtazi under different conditions. The results showed that the number of microorganisms in Youtazi decreased with the increase of irradiation dose, and the range of irradiation dose was 3~7 kGy. Irradiation can slow down the increasing trend of acid value in Youtazi during storage, and the higher the irradiation dose, the lower the acid value was. After irradiation, the peroxidation value of Youtazi did not change significantly during the storage period. But the higher the irradiation dose was, the longer the storage time was, and the more fluctuating the peroxidation value it was, which indicated that the higher the irradiation dose, the longer the storage time was, and the greater the influence on the peroxidation value of Youtazi it was. Irradiation treatment had a significant effect on the color difference value of Youtazi (P＜0.05). The L* value first decreased and then increased with the extension of storage time. The values of a* and b* both increased with the extension of storage time, and there was no significant correlation between the chromatic aberration of Youtazi and irradiation dose.
