摘要
采用平板计数法测定了10种市售卷烟接装纸的菌落总数,结果表明:(1)平板计数法适用于卷烟接装纸菌落总数的测定;(2)平板计数法检测接装纸菌落数重复性较好,同一稀释度(1:10)平行样检测结果的相对标准偏差(RSD)小于30%,同一样品平行样RSD小于20%;(3)不同接装纸样品差异性显著,同一厂家接装纸样品差异性不显著;(4)所测接装纸中的菌落总数均符合行业限量标准,可判定为合格.
The total number of colonies of 10 commercially available tipping papers was determined by the plate count method, and the results show that： （1） the plate count method is suitable for the determination of the total number of colonies of the tipping papers;（2） the reproducibility of the plate count method is relatively stable, the relative standard deviation（RSD） of the same dilution parallel （1：10） was below 30%, and the RSD of the same sample parallel is below 20%; （3） the difference between the different tipping papers is significant, while the difference among the tipping papers from the same manufacture is not;（4） the total number of colonies determined of all the 10 tipping papers is conforming the tobacco occupation limited standard.
