研究不同浓度乙醇熏蒸处理对马铃薯绿变和α-茄碱含量的影响。结果表明:在光照条件下,马铃薯表皮绿变程度和α-茄碱含量随着贮藏时间的延长而增加;不同浓度乙醇熏蒸处理可有效控制马铃薯绿变并对α-茄碱具有降解作用,贮藏到12 d,马铃薯表皮叶绿素含量与α-茄碱含量明显低于对照,其中1 000μL/L乙醇熏蒸处理效果最佳。

Effect of Different concentrations of ethanol vapor treatment on greening and α-solanine content of potatoes was investigated.Results showed that under fluorescent light,the greening level and α-solanine content of potatoes increased with prolonged storage time.Different concentrations of ethanol vapor treatment could effectively inhibit the greening level and degrade α-solanine content of potatoes.Until day 12 of storage,chlorophyll content and α-solanine content of potatoes peel were significantly lower than that of controls,among which,1 000 μl/L ethanol vapor treatment provided the best inhibitory effect.
