| 摘 要： | 目的]对不同水活度干奶粉中的单增李斯特氏菌在不同温度条件下的生存特性进行评估.方法]通过人工方法将单增李斯特氏菌按103cfu/g的浓度添加于不同水活度的干奶粉样品中,在不同温度(冰箱温度4℃和室温25℃)下贮存,通过菌落计数来分析单增李斯特氏菌的生存特性.结果]在低温条件下,单增李斯特氏菌可在较低水活度的干奶粉中长期保持生长活力,并且当水活度较高时,会有增长趋势.在较高的环境温度中,干奶粉中的单增李斯特氏菌的生长活力很快减退,细菌处于亚损伤状态,但在适宜的营养环境条件下,这种亚损伤状态可以得到修复.细菌仍然可以恢复活力.结论]高温条件更易使干奶粉中单增李斯特氏菌生长活力减退,干奶粉中如果污染了单增李斯特氏菌.于室温(25℃)条件下贮存会抑制单增李斯特氏菌的生长.

| Abstract: | To assess the growth and survival of Listeria Monocytogenes in spiked powered milk of different water activity at different temperature.Listeria Monocytogenes was added into powdered milk of different water activity at a density of 103 cfu/g,the spiked powered milk stored at the different temperature,the influence of different temperature and different water activity on the growth and survival of Listeria Monocytogenes in the powered milk was analyzed by counting.The temperature influenced the growth and su... |
