摘 要：以普洱茶为研究对象，利用60Co-γ射线辐照，初步研究了不同辐照剂量对普洱茶的杀菌效果及其品质的影响。结果表明：60Co-γ射线能有效地杀灭普洱茶中的微生物，产品初始微生物≤105 cfu/g，经3.6 kGy～5 kGy剂量辐照能确保普洱茶污染微生物的量低于1×103 cfu/g，且对其品质成份无明显影响。

Abstract：The purpose of this study was to analyze the effects of 60 Co gamma irradiation on the quality and sterilization of Puer-tea.The results showed that 60Co gamma irradiation could effectively kill the microbe contaminating puer-tea，controled the amount of microbe less than 1.0×103 cfu/g while the initial contaminated amount of microbe is Less Than 1.0×105 cfu/g, and had no significant influence on the principal sensory quality and components of Puer-tea at the doses of 3.6 kGy～5.0 kGy.
