我们评估了切割苹果的电性能与腐烂的发病率。从样品组织的电阻抗的频率特性制备Cole-Cole图，并用于腐烂样品的分析。所有样品的Cole-Cole图中圆弧顶部的坐标显示线性回归，估计坐标受细胞外液阻力的影响。根据腐烂的存在或不存在对样品的坐标进行分组。由此推断，坐标位置的降低是由细胞外液中细菌繁殖产生的代谢产物引起的。我们发现，科尔-科尔坐标图有潜力作为一个简单的，低成本的，定量标记，以帮助在切割苹果腐烂的快速判别。该方法可用于水果加工过程中采后病害的检测，有助于建立高质量的供应链和食品安全管理。
We evaluated the electrical properties of cut apples with and without rot incidence. Cole–Cole plots were prepared from the frequency characteristics of the electrical impedance of sample tissues and used for the analysis of the rotten samples. The coordinates at the top of the circular arc in Cole–Cole plots of all samples showed a linear regression, and it was estimated that the coordinates were influenced by extracellular fluid resistance. The coordinates of the samples were grouped according to the absence or presence of rot. It was deduced that the decrease in the position of the coordinates was caused by metabolites produced by multiplied bacteria in extracellular fluids. We showed that the Cole–Cole plot coordinates have potential as a simple, low-cost, and quantitative marker to aid in the rapid discrimination of rot in cut apples. This approach could be developed for use in the detection of postharvest disease during fruit processing, aiding in the construction of a high-quality supply-chain, and food-safety management.
