文献和实验市面上销售的食品均需经过质检部门的微生物检测,以确保食用安全。固体或液体样品在微生物检测前要经过处理才能进行后续分析。据统计样品前处理所用的时间占到整个检测时间的60%以上,且检测条件的不合格常会造成,因此提高样品前处理的效率、控制检测过程中的交叉污染对于整个食品微生物检测对具有重要意义。 样品前处理的流程大概如下:固体或液体样品采样25g/mL后,经过1:10的稀释,再进行均质处理,取得适于接种的样品溶液,用于后续微生物培养分析。 由上表看出,重量稀释和拍打均质的方法进行样品

kangyaojie 请问是在那个公司订购的,什么规格,什么价格?因为我也要用,谢了 hbqh 我用的是Sigma公司的,5g是700元左右,25g2700元多,货号是p8765 伽利略 PDTC 白色粉末,保存在4度冰箱就可以了,常温问题也不大,反正是粉末。 实际这个问题你没必要在这里问,直接打电话给西格玛公司询问就可以 hbqh 可是配好液体后怎么保存啊,说明书上说存在惰性
