食品包装热杀菌过程模型的建立及仿真研究进展

Research Progress on Model Establishment and Simulation of Thermal Sterilization Process of Food Packaging

通过计算机模拟技术研究食品热杀菌过程,可得到食品内部的温度、致死率、营养成分等数据变化趋势,从而确定有效的杀菌方案。本文从食品包装的角度,概述包装系统传热控制方程适用性、分析模拟过程误差产生原因,并对不同食品物料状态和包装形式研究进展进行归纳总结,为减少食品过度热杀菌提供理论支持。

Through computer simulation technology to study the process of food thermal sterilizationof food,the changing trends of data such as temperature,lethality,and nutritional components inside the food can be obtained,so as to determine an effective sterilization plan.This paper summarizes the applicability of the heat transfer control equation of the packaging system from the perspective of food packaging,analyzes the causes of errors in the simulation process,and summarizes the research progress of different food material states and packaging forms to provide theoretical support for reducing excessive heat sterilization of food.
