摘要

研究了3℃和10℃下二氧化碳(100%)、氮气(100%)、二氧化碳/氧气(20%:80%)或真空包装对去皮鸡胸片或鸡腿肉中微生物菌群的影响。在真空包装、二氧化碳和氮气保存的样品中,乳酸菌和热刺菌是优势菌。假单胞菌只在氧气/二氧化碳包装系统中生长。在3℃和10℃的温度下储存时,大腿肉和胸肉中的乳酸浓度都有所下降。在20%:80%的二氧化碳/氧气条件下储存的大腿肉中,乳酸浓度的下降更为明显。无论储存条件如何,所有样品中醋酸盐均有不同程度的增加。

Storage of poultry meat under modified atmospheres or vacuum packs: possible role of microbial metabolites as indicator of spoilage.

The effect of carbon dioxide (100%), nitrogen (100%), carbon dioxide/oxygen (20%:80%) or vacuum pack at 3 and 10 degrees C was studied on the microbial flora, in skinless poultry breast fillets or thigh meat. Lactic acid bacteria and Brochothrix thermosphacta were the predominant organisms in samples stored in vacuum packs, carbon dioxide and nitrogen. Pseudomonads grew only in oxygen/carbon dioxide packaging systems. The concentration of lactate diminished in both thigh and breast meat during storage at 3 and 10 degrees C. This decrease was more pronounced in thigh meat stored under 20%:80% carbon dioxide/oxygen. Acetate increased to varying degrees in all samples regardless of the storage conditions.
