| 摘 要： | 为选出高压电场调控番茄后熟衰老贮藏的有效条件，以“朝研219”番茄为试材，以果实硬度和颜色转化及腐烂指数为评价指标，研究不同电场处理方式对番茄贮藏效果的影响，从而筛选出电场处理提高番茄贮藏效果的有效条件。结果表明：经－ 200kV/m、2h/d 的间歇稳恒电场和－ 200～200kV/m 波动场强、2h 的交变电场一次预处理方式能够显著延缓番茄果实硬度的下降和颜色的转化，并降低腐烂指数(P ＜ 0.05)；而稳恒电场和交变电场持续作用于果实时，可促进果实成熟。筛选出的电场处理方式均可延缓番茄的后熟衰老，延长果实贮藏期。

| Abstract: | The effect of high voltage electric fields on the after-ripening process and quality during storage of ZhaoYan219 tomatoes (Lycopersicom esculentum) was investigated. The firmness, color and decay index of electric field-treated tomatoes were determined during storage. The optimum conditions of electric field treatment were optimized. The results showed that －200kV/m of intermittent static electric field treatment (2 h/d) and －200～200 kV/m 40 kHz alternating electric field pre-treatment (2 h) delayed significantly the decline of firmness, the change in color from green to red of tomato fruit during storage, and decreased the decay index (P ＜ 0.05), and thus prolonged the storage time of tomatoes. However, continuous treatment of intermittent static field and alternating electric field accelerated the ripening process. |
