本文考察了KI和I2对红提葡萄贮藏过程中SO2伤害的防止的效果,研究发现分别在采前喷淋KI、I2或其混合物不会削弱SO2的防腐效果，其中I2可增强了它的防腐效果，但会削弱SO2的抗菌效果；KI可增强SO2的防褐变效果。

The effects of KI and I2 on preventing the damage of SO2 on the red Grape during storage process were explored. The results showed that spraying KI, I2, or their mixture before picking the grape did not influence the preservative effect of SO2. And I2 could enhance the antiseptic effect of SO2, but weaken its anti-browning effect, while KI ccould enhance its anti-browning effect.
