| 摘 要： | 研究了番茄采后成熟过程中果皮颜色的变化规律，发现色泽角（H°）、色泽比（a/b）和明度等主要颜色参数的变化均符合一级动力学模型，并由实验确定了各颜色模型的动力学参数：参考变化速率常数（Kref）和反应活化能（Eα）。在此基础上，设计了一个色泽角-时温预测器，能够预测和监控果实采后贮藏的品质变化。

| Abstract: | In this paper, kinetic models were derived for surface color changes in tomato fruits during ripening. The results showed that changes of H °, a/b and L-value in tomato fruits during storage followed a first orde r reaction kinetics. The rate constants (Kref) and activation energy v alue (Eα) at reference temperature of 13℃ were calculated respectively. A time- temperature indicator based on the Hue angle models was designed for predicting and controlling the quality changes of tomato fruits during storage. |
