| 摘 要： | 在裸露条件下对无菌酱牛肉进行外部环境中微生物污染情况的试验。试验结果表明,使用灭菌后的酱牛肉样品直接暴露在市场环境中,按0h、1h、2h、4h、8h5个时段分别取样观察,结果显示金黄色葡萄球菌未检出,霉斑未形成。4h后菌落总数开始呈现明显上升趋势,从1h开始就有样品检出大肠菌群,6h时平均大肠菌群数就已经超过国家标准。而使用保鲜膜对灭菌后的酱牛肉样品进行简易包装后置于市场环境中,按0h、1h、2h、4h、8h5个时段分别取样观察,结果显示金黄色葡萄球菌未检出,霉斑未形成,8h后菌落总数未呈现明显上升趋势,大肠菌群未检出。说明简易包装能明显抵御外部环境中微生物的污染。

| Abstract: | Experiments on microbial contamination of aseptic sauce beef samples in the markets directly without any covery on the surface were made in this study. Sample and test the samples after 0 h,1 h,2 h,4 h,and 8 h. The results showed that,staphylococcus aureus and mould spots could not be checked. The total number of bacteria increased obviously after 4 h. E. coli count began to increase at 1 h and after 6 h it was above the national standards. Place the aseptic sauce beef which was packaged in cling film in th... |
