Measurements and predictions of growth for Listeria monocytogenes and Salmonella during fluctuating temperature II. Rapidly changing temperatures

Growth of Listeria monocytogenes and Salmonella was examined during various rates of increase ana decrease in temperature from and to the minimum for growth. Growth was little affected by even the most rapid changes and injur y or lag was not observed. Subsequent investigations of growth during perio ds of rapid variation in temperature from and to temperatures below the gro wth minimum again had little effect and growth was satisfactorily predicted using the dynamic model of Baranyi and Roberts [Int. J. Food Microbiol. 23 (1994) 277] in conjunction with the data of Food Micromodel. (C) 2001 publ ished by Elsevier Science B.V.
