Based on the cold fresh duck with modified atmosphere packaging, in order to simulate the condition that the initial colony count is different in different batch cold fresh duck during the process of logistics and pro-cessing in marketing,the cold fresh duck meat was stored at incubator for 4℃for 0,1,2,3 d respectively to pro-duce four differents initial colony count of cold fresh duck material in the paper,and the effect of the differences of the initial colony count on the growth prediction model on Pseudomonas was studied. The results indic...
