Abstract: Main microorganisms of chilled mutton were incubated with selective agars, and initial microflora and their changes under vacuum were analyzed. The results showed: Pseudomonas, Lactobacillus, Brochothix thermosphacta and Enterobacteriaceae were the main microorganisms in the chilled mutton; Lactobacillus increased progressively and became dominant microflora fast during storage in 4℃. However, Pseudomonas and Brochothix thermosphacta gradually decreased and Enterobacteriaceae was unchanged almost; Lactobacillus restrained the growths of Pseudomonas, Brochothix thermosphacta and Enterobacteriaceae seriously.
