Abstract:
The aim of this research was to study the effect of ultraviolet irradiation, γ irradiation, and a combination of the two on the degradation of aflatoxin B1 (AFB1) in soybean. In this work, fresh soybean was used as the raw material, and contaminated soybeans that contained 0.1, 0.5, and 1.0 mg AFB1/kg soybean were obtained by adding AFB1 to soybean. The ultraviolet irradiation intensity had a significant influence on the degradation of AFB1 (P<0.05), whereas the moisture content and AFB1 content had no significant effects on the degradation (P>0.05). The degradation of AFB1 increased with increasing ultraviolet irradiation time up to 10 min, after which the degradation ratio remained stable. On the other hand, the degradation of AFB1 increased with increasing γ irradiation dose and moisture content, but decreased with increasing AFB1 content. The γ irradiation dose, moisture content, and AFB1 content had a significant influence on the degradation of AFB1 (P<0.05). A synergistic effect between ultraviolet irradiation and γ irradiation was also observed.
