Abstract

To explore the growth-inactivation-regrowth ecological behavior of Listeria monocytogenes in food with the change of food chain related conditions, this paper reviewed the influencing factors, model development and related mechanisms of the ecological behavior of L. monocytogenes under the condition of thermal processing. It is found that in the process of "growth-inactivation", the historical growth conditions of cells have an influence on their inactivation characteristics, while in the process of "inactivation-regrowth", the lag period of cells has been influenced by the historical physiological state. Therefore, the growth and inactivation of L. monocytogenes in food should not be modeled as two separate processes. It is necessary to study the ecological behavior of the cells during continuous changes in environmental conditions, with a view to providing support for food risk assessment and food safety.
