Zizania latifolia is easily lignified after harvesting, leading to the degradation of food quality and commercial value. Thus, this study evaluated the effect of radio frequency (RF) treatments on lignification inhibition of Zizania latifolia. The results showed that the lignin content of Zizania latifolia treated with RF decreased significantly compared with the control group. At the 7th day of storage, the phenylalanine ammonia lyase activity of the 90 W RF treatment group decreased by 52.9% compared with the initial value. The activities of peroxidase and polyphenol oxidase in the stems of Zizania latifolia were significantly (p < 0.05) decreased after RF treatments. Besides, a decrease in conversion rate of O2 - and H2O2 to downstream products was observed, indicating that the related invertases were inhibited by RF treatment. All of these showed that RF treatments contribute to inhibit or delay the lignification of Zizania latifolia, providing a better taste and quality for products.

采收后射频处理对Z子木的木质化的抑制作用。

收获后的Zizania latifolia容易被木质化，导致食品质量和商业价值下降。因此，本研究评估了射频（RF）处理对Zizania latifolia木质化抑制的影响。结果表明，与对照组相比，RF处理的Zizania latifolia的木质素含量明显降低。在储存的第7天，90 W RF治疗组的苯丙氨酸氨裂合酶活性与初始值相比降低了52.9％。射频处理后，Zizania latifolia茎中的过氧化物酶和多酚氧化酶活性显着降低（p <0.05）。此外，观察到O 2-和H 2 O 2向下游产物的转化率降低，表明相关的转化酶被RF处理抑制。
