Che Fangping;Zhao Mengyun;Chen Yan;Hangzhou Pooke Testing Technology Co., Ltd.;
According to national standard GB 4789.2-2016 National food safety standards Microbiological examination of food Total Detection of number of colonies detect the same batch of 10 green pellet, and by analyzing other sources of uncertainty, obtain the uncertainty and extended uncertainty of the total number of colonies. And the conclusion is: Value interval of total number of colonies of the sample to be tested(average of ten sample measurements after logarithm) is [y--0.15,y-+0.15].
