Dielectric measurements (from 500 MHz to 20 GHz) on different standard solutions (K(+), malic acid) with different sugar contents were assayed simulating concentrations of these substances during apple ripening. These assays were performed for considering the potential use of dielectric spectra (500 MHz to 20 GHz) to determine the optimal time for eating the fruit. Good correlations between a newly defined dielectric maturity index and the Thiault index were found. This work presents prospective data of dielectric spectra for certain apple key chemical components in order to consider its potential application as a nondestructive control sensor for the prediction of climacteric fruit maturity.
对不同含糖量的标准溶液（K(+)、苹果酸）进行了从 500MHz 到 20GHz 的介电测量，模拟了苹果成熟过程中这些物质的浓度。这些测量是为了考虑介电谱（500MHz 到 20GHz）在确定食用水果的最佳时间方面的潜在应用而进行的。发现新定义的介电成熟指数与 Thiault 指数之间存在良好的相关性。这项工作提供了某些苹果关键化学成分的介电谱的预期数据，以考虑其作为非破坏性控制传感器预测呼吸跃变型果实成熟度的潜在应用。
