Identification of Kiwifruit and Peach Varieties Based on Dielectric Properties
摘要
Abstract
Abstract. In this study, two kiwifruit cultivars, Qinmei and Hayward, and two peach cultivars, Qinguang No. 2 and Qinwang were used to explore the feasibility of distinguishing different fruit varieties based on electrical properties (complex impedance Z, parallel equivalent inductance Lp, loss coefficient D, impedance phase angle θ, equivalent series resistance Rs, conductivity G and parallel equivalent capacitance Cp). The results showed that a good linearity was found for the lgZ-lgfand lgLp-lgf relationships of kiwifruit and peach with R2 〉 0.95. Kiwifruit and peach could be distinguished by D value in the exciting frequency range of 100 Hz-- 1.58 kHz, by θ and Rs values in the range of 100 Hz--6.31 kHz, and by G value in the range of 100 Hz-- 100 kHz. Hayward, Qinmei, Qinwang and Qinguang No. 2 were distinguished by Z value in the range of 15.8-- 100 kHz and by Cp in the range of 100 Hz -- 158 kHz.关键词
