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。

关 键 词:番茄果实    果表颜色    动力学模型    时温预测器

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.
Keywords:tomato fruits  surface color  kinetic model  time-temperature indicator
