杨梅脱氧活性包装研究

Study on Active Packaging with Deoxidizer of Red Bayberry

对浙江仙居地区杨梅进行了自发气调包装和脱氧活性包装的对比试验,结果表明:脱氧活性包装能明显降低其腐烂率,延长其贮藏期,贮藏期由自发气调包装的4 d延长到8 d,腐烂率由31%降低到15%。脱氧活性包装还能延缓杨梅硬度和糖度的下降。正交试验结果显示,活性包装杨梅的最佳条件是:温度10℃,脱氧剂0.370 g,湿度调节剂2.575 g。

Zhejiang Xianju red bayberry fruit is stored in the modified-atmosphere packages and active packaging with deoxidizer. The result shows that the rot rate of red bayberry fruit can be reduced from 31% in the modified-atmosphere packages to 15% by the active packaging, and the storage period can be prolonged from 4 days in the modified-atmosphere packages to 8 days by the active packaging. The rigidity and the sugar degree of fruit can be reduced more effectively by the active packaging than by the modifiedatmosphere packages. According to results of orthogonal experiments, the optimum conditions of active packaging with deoxidizer are Temperature10℃, the dosage of deoxidizer 0. 370g, the dosage of humidity regulator 2. 575g.
