本文通过乳制品微生物活性快速检测仪对鲜乳中微生物酶活性的测定，快速检测鲜乳中微生物数量的变化，判定鲜乳品质的优劣。试验结果表明：仪器法可以在30min内完成一个鲜乳样品的微生物含量的检测。利用鲜乳微生物快速检测仪和国标平板菌落计数法分别检测大肠杆菌、蜡样芽胞杆菌、变形杆菌、灰绿曲霉、黑曲霉、球拟酵母菌、金黄色葡萄球菌、伤寒沙门氏菌和志贺氏菌等主要危害鲜乳品质的菌落数量，两种方法的测定结果相关系数均在0.98以上，这表明两种方法间有很好的线性相关性，同样用两种方法监测鲜乳贮藏过程中的微生物活动情况，其检测结果R2=0.991，属于显著相关。
本文通過乳製品微生物活性快速檢測儀對鮮乳中微生物酶活性的測定，快速檢測鮮乳中微生物數量的變化，判定鮮乳品質的優劣。試驗結果錶明：儀器法可以在30min內完成一箇鮮乳樣品的微生物含量的檢測。利用鮮乳微生物快速檢測儀和國標平闆菌落計數法分彆檢測大腸桿菌、蠟樣芽胞桿菌、變形桿菌、灰綠麯黴、黑麯黴、毬擬酵母菌、金黃色葡萄毬菌、傷寒沙門氏菌和誌賀氏菌等主要危害鮮乳品質的菌落數量，兩種方法的測定結果相關繫數均在0.98以上，這錶明兩種方法間有很好的線性相關性，同樣用兩種方法鑑測鮮乳貯藏過程中的微生物活動情況，其檢測結果R2=0.991，屬于顯著相關。

Method of fast detecting fresh milk microorganism was investigated by determining the enzyme activity with quick microorganism detector, which could monitor quality of fresh milk. Experimental results showed that detection of microbial content instrument method could be accomplished with a fresh milk samples in 30 minutes. Detect Escherichia coli, Bacillus cereus, Bacillus Proteus, Aspergillus glaucus, Kuroma, Torulopsis, Staphylococcus aureus, Salmonel-la typhi, Shigella and other major hazards of fresh milk quality by the number of colonies using fresh milk microbial rapid detection instrument and standard plate count method. Determination results of two methods of correlation coefficient was above 0.98, indicating that two methods had good linear correlation. Microbial activity of fresh milk two methods during storage, the R2=0.991, which belonged to significant correlation.
