Optimal characterization of thermal microbial inactivation simulating non-isothermal processes.
Food Research International(2018)
摘要
In this paper, optimal experimental design is applied for the characterization of the microbial inactivation of Listeria monocytogenes under non-isothermal conditions, modelled by the Bigelow model. These conditions simulate industrial processes, where different temperature profiles can be applied for food processing. Here, the aim was to find the best time nodes for measurements given a fixed number of observations and a final time process. Results show that, compared to a “classic” uniform time distribution for the observations, the optimal distribution of observation times results in a more accurate description of the response of the microbial population. The OED resulted in a reduction in the relative standard errors for the estimated D and z-values of 25% and 80%, respectively.
