Physical damage of fruits and vegetables during distribution accelerate their decline in quality during storage. This study was aimed to analyze the quality degradation that takes injuries into consideration by using estimation models. Estimation models for bruised “Shine Muscat” grapes during storage were investigated based on bio-electrochemical theory. An electrical indicator, LTO, defined as the length from the origin of the coordinate at the top of the circular arc of the Cole−Cole plot, was demonstrated to effectively quantify the degree of a bruise with high accuracy (r² > 99). The color-change kinetics constant increased as LTO decreased, and a strong correlation was confirmed between these two parameters (p < 0.01). These results demonstrate that the LTO parameter can be used to characterize physical damage incurred by the fruit, and it may be used as an injury parameter to calculate their color-change kinetics constant during storage after physical damage.

水果和蔬菜在分配过程中受到的物理损害会加速其在存储过程中质量的下降。这项研究旨在通过使用估计模型来分析考虑到伤害的质量下降。基于生物电化学理论，研究了青贮的“光亮麝香葡萄”葡萄在贮藏过程中的估计模型。电气指示器LTO定义为距Cole-Cole曲线的圆弧顶部的坐标原点的长度，可以有效地准确量化瘀伤的程度（r ²  > 99）。随着LTO的降低，变色动力学常数增加，并且证实了这两个参数之间的强烈相关性（p <0.01）。这些结果表明，LTO参数可用于表征水果引起的物理损伤，并且可以用作伤害参数来计算其在物理损伤后储存期间的变色动力学常数。
