    摘要:

    为考察电子束辐照对玉米中黄曲霉毒素B1(aflatoxin B1,AFB1)的降解效果及对玉米品质的影响,试验选取AFB1污染的玉米为原料,研究0~50 kGy剂量辐照下玉米中AFB1的降解效果,并考察电子束辐照对玉米理化性质,包括脂肪酸值、黏度值和色度的影响。结果表明,随着电子束辐照剂量的升高(5~50 kGy),玉米中AFB1含量显著降低(P<0.05);当电子束辐照剂量大于15 kGy时,玉米理化性质变化较明显,其中脂肪酸值显著升高(P<0.05),黏度值显著下降(P<0.05),L*值无显著变化(P>0.05),a*,b*值显著下降(P<0.05)。

    Abstract:

    To study the detoxification effect of electron beam irradiation on AFB1 in corn, the effect of electron beam irradiation on the AFB1-contaminated corn based on the doses of 0~50 kGy was studied. Physicochemical properties including fatty acid, color and viscosity of AFB1-contaminted corn at different irradiated doses were also investigated. Results indicated that AFB1 in corn significantly decreased with the irradiation dose (P<0.05). Moreover, physicochemical properties changed significantly when the irradiation dose was over 15 kGy, including the significant increase of fatty acid value (P<0.05) and the decrease of the viscosities (P<0.05). It was found that the whiteness didn’t change significantly (P>0.05), while the significantly decreased redness and yellowness (P<0.05) were observed.
