35 loin muscle samples were collected from market at random, in order to research the variation and relationship between TVB-N and conductivity of fresh pork in the corruption process. The results showed that the porkwas kept at the temperature of 30 ℃ and humidity of 85% for 3 days, TVB-N and conductivity were gradually increased with the corruption of pork.In different time periods, correlation test between conductivity and TVB-N value were of highly significant (P<0.01) with the correlation coefficient being of 0.926. Conductivity and TVB-N presented a linear regression relationship and the regression equation was y=50.582x-54.452 (P<0.01). The coefficient of determination was 0.857 and conductivity value was ≤1.37 mS/cm. Therefore the pork can be assessed as fresh pork.
