为了建立肉品微生物快速检测方法,选取了180块外脊冷鲜牛肉作为研究材料,在其4个最易受污染的上表面、外侧面、内侧面、切面进行表面微生物总数测定,然后将肉样整体打碎后进行总体微生物总数测定.对外脊冷鲜牛肉各表面微生物与总体微生物相关分析表明：切面微生物数量与总体微生物数量相关性最高,y=0.7017x+1.2526,r 2=0.7153；内侧面微生物与总体微生物相关性次之,y=0.5194x+1.8077,r 2=0.659；外侧面微生物与总体微生物回归方程为：y=0.5879x+1.729,r 2=0.6006；上表面微生物与总体微生物相关性最低,y=0.6902x+1.3164,r 2=0.5749.

In order to set up a rapid detection method of microorganism of beef,180 outside ridge of chilled beef were elected as the research material.The bacterial count of upper surface,outer side surface, inner side surface ,cut surface and overall beef were detected.The correlation analysis shows that the cut surface bacterial count has the highest relaltion to overall bacterial count,the regressive equation is y=0. 701 7x+1.252 6,r 2=0.715 3.The regressive equation of facies medialis baterial count to overall bacterial count is y=0.569 4x+1.807 7,r 2=0.659 2.The regressive equation of facies lacteralis to overall bacterial count is y=0.587 9x+1.729 5,r 2=0.600 6.The smallest relaltion to overall bacterial count is the upper surface bacterial count.The regressive equation is y=0.690 2x+1.31 6 4,r 2=0.574 9.
