1-MCP对不同成熟度猕猴桃电特性的影响
Influence of 1-MCP on Dielectric Properties of Kiwifruit at Different Maturities
摘要
Abstract
In this study, ＇Hayward＇ kiwifruit at the appropriate harvest （maturity Ⅰ, with a TSS of 6.2%） and late harvest （maturity Ⅱ, with a TSS of 8.8%） was used to investigate the effect of 0.5μL/L 1-methylcyclopropene （1-MCP） on postharvest electric properties of fruits at room temperature （20 ℃）. Kiwifruits at maturity I revealed a remarkable increased in impedance （Z） at the frequency of 1 MHz when compared with those at maturity II and a significant difference in Z value began appearing on storage day 7 （P 〈0.05）. The same results were observed for capacitance in the parallel equivalent circuit mode （Cp） at 10 kHz. 1-MCP inhibited the decrease of Z value in kiwifruit with prolonged storage period at 0.1 kHz or 1 MHz. 1-MCP-treated kiwifruit presented a significantly higher Cp at 10 MHz than the control. However, inductance in parallel equivalent circuit mode （Lp） and impedance phase angle （θ） had insensitive response to fruit maturity and 1-MCP, and consequently was not a measure of maturity and 1 MHz treatment or not.关键词
