| 摘 要： | 采用选择性培养基，分别对冷鲜猪肉内外的菌相组成进行分析鉴定，并研究其在储藏过程中的变化规律。实验鉴定出热杀索丝菌、假单胞菌、乳酸菌、肠杆菌科各2株以及葡萄球菌属1株；热杀索丝菌为托盘包装冷鲜猪肉的主要优势菌；整个培养过程中肠杆菌科和假单胞菌生长趋势明显；肉块内部的微生物生长速度高于肉块表面。

| Abstract: | Both internal and external bacteria floras in fresh chilled pork were analyzed and identified using selective medium,and their changes during the whole storage period of 8 days were also studied.Brochothrix thermosphact,Pseudomonas,Lactic acid bacteria,two strains of Enterobacteriaceae and a Staphylococcus were identified.B.thermosphact was the dominating spoilage bacteria of pallet packaged chilled pork.During the whole storage,Pseudomonas and Enterobacteriaceae had obvious growth and the microbes inside p... |
