摘要:

作者以破壁灵芝孢子粉为材料，研究了电子束和γ射线两种射线的不同辐照剂量对灵芝孢子粉微生物和品质的影响。结果表明：两种射线辐照对产品微生物和多糖质量分数变化基本一致。电子束和γ射线辐照灵芝孢子粉菌落总数的D10值分别为2.167 kGy和2.172 kGy，霉菌与酵母菌的D10值分别为2.646 kGy和2.452 kGy；当辐照低于8 kGy时，电子束和γ射线辐照对灵芝孢子粉的多糖质量分数均无明显影响，而高于8 kGy时，其多糖质量分数有显著变化。因此，低于8 kGy的辐照剂量可视为破壁灵芝孢子粉安全辐照剂量。

Abstract:

In this study，the survival microorganism and quality of Ganoderma lucidum spore powder affected by electron beam and γ-rays was studied. The results showed that the microorganism and quality affected by electron beam was accordance with that of γ-rays. The D10 values of electron beam and γ-rays irradiation for aerobic bacterial count were 2.167 kGy and 2.172 kGy respectively，whereas the D10 values of mould and yeasts were 2.646 kGy and 2.452 kGy，respectively. When the irradiation dose was lower than 8 kGy，ganodermic polysaccharide of Ganoderma Lucidum spore powder was not significant difference irradiated by this two models. However，when the irradiation dose was higher than 8 kGy，the significant difference of ganodermic polysaccharide of Ganoderma lucidum spore powder was found. The irradiation dose of Ganoderma lucidum spore powder was best to lower than 8 kGy.
