摘要

本文提出了一种提取瓜皮和瓜籽中果胶的新模式。该方法基于在 70、80 和 90 摄氏度的酸性介质中萃取果胶 180 分钟,评估产品在每个温度下的性能。无论工作温度如何,从瓜皮和瓜籽中提取果胶的动力学都呈现出三个阶段:快速释放,然后是平稳期,接着是平稳增长,直至达到提取产品的最大数量。这一过程可以理解为一系列子过程,每个子过程都有自己的延迟时间和恒定时间。根据实验结果,每个阶段或时期都被数学模型化为具有延迟时间的二阶线性。这一动态模型考虑到了工作矩阵以及所使用的提取机制。与文献中关于果胶提取的经验和机理模型相比,该模型与实验数据的偏差极小。后者基于过于简化的假设,导致实验结果与数学模拟结果之间存在巨大差异。

Mathematical Modeling for Pectin Extraction in Melon waste
This article proposes a novel model for the extraction of pectin in melon peels and seeds. The methodology is based on the extraction of pectin in an acid medium for 180 minutes at 70, 80, and 90C, evaluating the performance of the product at each temperature. The kinetics of pectin extraction from melon peels and seeds, regardless of the working temperature, presents three stages: rapid release, then a plateau, followed by smooth growth until reaching the maximum amount of the product extracted. This process can be assimilated as a sequence of subprocesses, each with its own delay time and constants time. Based on the experimental results, each stage or period is mathematically modeled as a second-order linear with delay time. This dynamic model takes into account the work matrix, as well as the extraction mechanism used. The deviation of the model concerning to the experimental data is minimal, compared to the empirical and mechanistic models found in the literature for pectin extraction. The latter are based on oversimplified assumptions, leading to significant disparities between experimentally obtained and mathematically simulated results.
