ABSTRACT:
A method for predicting the future acceptability of coarsely ground beef after regrinding and aerobic storage under specified conditions of time and temperature by measurement of the concentration of lactic acid in the sample is described. The method includes the steps of setting up a data base which relates the values of the initial concentration of lactic acid in samples of coarsely ground beef to odor acceptability of the samples after regrinding and aerobic storage for specified conditions of time and temperature, and measuring the initial lactic acid in the test sample and predicting future acceptability with reference to the data base. Based on the prediction value, a decision is made whether the beef is acceptable for the intended purpose.
