| 摘 要： | 本文研究了辐照对螺旋藻的杀菌效果。螺旋藻经7kGy辐照处理后,总带菌量(包括细菌和霉菌)可从初始值105CFU/g数量级水平迅速降至低于102CFU/g,大肠杆菌降为0。辐照后4个月的室温储藏也能保持较高的卫生质量。经同样辐照剂量处理后于37℃、85%RH条件下储藏4周,发现水活度为0.81的样品中微生物(细菌和霉菌)繁殖速度要远大于水活度为0.72和0.66的样品,可见辐照灭菌时较低的水活度是一个关键因素。

| Abstract: | The effects of irradiation on spirulina were studied in this paper.Investigation shows that 7kGy irradiation can reduce the total microorganism population in spirulina product from 10~5 to 10~2CFU/g,and keep sanitation quality well in four-month storage.The microorganism in the samples with water activity 0.81 grow more rapidly than in those with 0.72 and 0.66,which indicate that water activity is a important factor in the storage. |
