摘 要：
研究了60Coγ射线辐照香菇复合调味品的杀菌效果以及其对感官品质和主要理化品质指标的影响。结果表明,辐照可有效地杀灭香菇复合调味品中的杂菌和霉菌。随着辐照剂量的增加,调味品中的含菌量呈下降趋势,辐照对霉菌的杀灭效率高于杂菌,2.8 kGy辐照剂量处理后霉菌的存活率仅为0.67%,杂菌的存活率为10.95%,杂菌的D10值为2.63 kGy。与对照相比,经2.8 kGy辐照处理的香菇复合调味品,其主要理化品质指标(氨基酸态氮、呈味核苷酸二钠、总氮、粗多糖)无显著变化,感官品质亦无明显变化。

摘 要：
Sterilization of compound condiment of Lentinus edodes(CCLE) by 60Co γ-ray and the impact of irradiation on its quality indices as well as sensory quality were studied.The results showed that irradiation could effectively kill the bacteria and moulds in CCLE;The bacteria and moulds decreased with the increasing of the irradiation dose;The moulds decreased faster as its survival rate was merely 0.67% in CCLE 4 days after irradiated by 2.8 kGy 60Co γ-ray while that of the bacteria was 10.95%.The D10 value for bacteria was 2.63 kGy.Irradiation at a dose of 2.8 kGy had no significant effects on sensory quality or quality indices(amino acid nitrogen,I+G,total nitrogen,crude polysaccharide) of CCLE.
