布朗李果实耐藏性与简易气调贮藏试验

Piilot study of Different Varieties and The Effects of Guichuang Sack Controlled Storage on Plum

通过测定果实硬度、固酸比、褐变率、气体变化等分析布朗李不同品种的耐藏性。同时设计包装、乙烯脱除剂等不同处理组合探讨简易气调贮藏布朗李的效果。结果表明,黑宝石、威克森在2个月的贮期内,其硬度、固酸比、褐变率变化均小于黑琥珀、圣玫瑰、玫瑰皇后。在包装与气体处理组合中,硅窗袋、乙烯脱除剂组合能明显地抑制黑宝石布朗李品质指标的下降,使O2浓度明显低于对照,并稳定在0.5%左右,释放的乙烯浓度也较低,起到明显的气调贮藏作用。

Through analying the difference between varietie of plums,the results show that heibaoshi plum and Weikesen plum are more storaged than Hei hupo plum,Meiguihuanghou plum and Shengmeigui plum.Firmness and the ratio of soluble solid content to titration acid of storaged plum can be well maintained when packed in Guichuang sack and treated with ethylene absorbent,the Heibaoshi brown of plum can be reduced after 30 d of CA storage. In addition all varieties of plums have no obivious bounce of respiration in the refrigeratory storage.
