Abstract Migration kinetics of a polymer-food system can be studied using physical parameters such as the diffusion (D), partition (Kp,f), and convective mass transfer (h) coefficients. A mathematical model considering all three important migration parameters was proposed in part I of this paper series. However, there are other existing mass transfer models focus solely on either D and/or Kp,f. With various options available, how would a researcher choose an appropriate mathematical model for investigating the kinetics migration of a food packaging-simulant system? To address this question, this paper analyzes and compares the newly proposed mathematical model with the existing ones using a selected migration case study. Based on the output, a decision tree analysis for determining mass transfer parameters for migration studies is proposed. The decision tree analysis was beneficial as guidance and was able to provide an insight into the kinetic behaviors of a migrant in a polymer-food system by providing a method to select the right model for the aforementioned system.

抗氧化剂从聚乳酸薄膜中的迁移，一种参数估计方法：第二部分——分配、扩散和对流传质系数的评估

摘要 聚合物-食品系统的迁移动力学可以使用物理参数进行研究，例如扩散 (D)、分配 (Kp,f) 和对流传质 (h) 系数。本系列论文的第一部分提出了一个考虑所有三个重要迁移参数的数学模型。然而，还有其他现有的传质模型仅关注 D 和/或 Kp,f。有了各种可用选项，研究人员将如何选择合适的数学模型来研究食品包装模拟系统的动力学迁移？为了解决这个问题，本文使用选定的迁移案例研究，对新提出的数学模型与现有数学模型进行了分析和比较。基于输出，提出了用于确定迁移研究的传质参数的决策树分析。
