The correlation analysis between surface and the overall microbial count of beef

In order to set up a rapid detection method of microorganism of beef,180outside 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,r2=0.715 3.The regressive equation of facies medialis baterial count to overall bacterial count is y=0.569 4x+1.807 7,r2=0.659 2.The regressive equation of facies lacteralis to overall bacterial count is y=0.587 9x+1.729 5,r2=0.600 6.The smallest relaltion to overall bacterial count is the upper surface bacterial count.The regressive equation is y=0.690 2x+1.316 4,r2=0.574 9.
