Comparison of Arrhenius‐type and Bêlehrádek‐type models for prediction of bacterial growth in foods

摘要: D.A. RATKOWSKY, T. ROSS, T.A. WCMEEKIN AND J. OLLEY. 1991. The development of Arrhenius-type (‘Schoolfield’) and Belehradek-type (square root) models that describe microbial growth rates is briefly described. Both types model have been advocated for use in predictive microbiology. On the basis published data sets bacteria, consequences mathematical transformation invalid stochastic assumptions upon predictions are demonstrated. Mean square error shown to be an inappropriate criterion by which compare performance models. show bacterial responses such as generation time lag become more variable their mean magnitude increases. practical variability microbiology discussed.
