over-prediction tend to cancel out, the accuracy factor can be calculated. As shown in Table 2 for the studied models, the values of accuracy factor indicate that on average the predictions differ from observations by 5% and 38% for square root and Arrhenius models, respectively. These results corroborate that Arrhenius equation failed to accurately predict LAB growth rate in the studied meat emulsions. Although the differences observed between the models, the obtained values may be considered satisfactory on the bases that these were derived from data obtained using non-sterile and inhomogeneous food. Dalgaard and Jrgensen (1998) calculated accuracy factors ranging from 1.4 to 4.0 for growth rates of Listeria monocytogenes in various types of seafood.
