摘要: 本文采用选择性培养基对冷却羊肉中的主要微生物进行了选择培养,分析研究了真空条件下冷却羊肉的菌相消长规律。结果表明:假单胞菌、乳酸菌、热死环丝菌和肠杆菌是构成冷却羊肉初始菌相的主要微生物;4℃冷藏过程中,乳酸菌的含量呈上升趋势,并快速成为绝对优势菌群,热死环丝菌和假单胞菌的含量呈下降趋势,肠杆菌的含量变化较小;乳酸菌的增长严重地抑制了假单胞菌、热死环丝菌和肠杆菌的增长。

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.
