摘要
[目的]研究伊宁市生鲜乳中主要微生物的含量,为散装生鲜乳销售环节的卫生质量安全检测研究提供参考。[方法]针对新疆伊宁市8个不同片区售奶站进行采样,研究不同季节生鲜乳中菌落总数、大肠菌群数、芽孢总数和耐热芽孢总数的含量变化。[结果]2014年6月~2015年5月期间,伊宁市8个售奶站的生鲜乳在感官方面色泽、滋味、气味均正常,且不存在凝块、沉淀、肉眼可见异物现象;主要微生物含量指标菌落总数、大肠菌群数、芽孢总数和耐热芽孢总数分别为:3.08×105~8.48×105 CFU/mL、1.5×105~8.1×105 MPN/L、21~75 CFU/mL和3~8 CFU/mL,均符合国家标准。但散奶户所销售的生鲜乳中检查出微生物的含量要明显高于售奶站的鲜乳。[结论]新疆伊宁市部分奶站所售生鲜乳中主要微生物含量各项指标整体均符合国家标准,反映出伊宁市生鲜乳卫生管控整体水平较高。
Abstract
Objective] The aim was to study major microorganism content in raw milk in Yining City , provide reference for quality detection in sales link of bulk raw milk.[Method] Collecting samples from milk stations in 8 districts of Yining City, the changes of total bacterial colo-nies, total coliform groups, total spores and heat-resistant spores were studied.[Result] During June 2014-May 2015, color, taste and smell of raw milk from 8 milk stations in Yining were normal, and there was no block, precipitation and visible foreign matter phenomenon;The con-tent of total bacterial colonies, total coliform groups, total spores and heat-resistant spores were 3.08 ×105 -8.48 ×105 CFU/mL, 1.5 × 105 -8.1 ×105 MPN/L, 21-75 CFU/mL and 3-8 CFU/mL, respectively.The content of microorganisms in fresh milk sold by the scattered milk households was obviously higher than that of the milk station.[ Conclusion] The indicators of main microorganisms content in raw milk from some milk stations in Yining City are in line with national standards , reflecting the overall level of health management and control of fresh milk in Yining City is relative high.
