摘要
以‘巨峰’葡萄为实验对象,自制分别由两片和三片功能膜组成的双功能集成包装(dual-functional integrated packaging,DFIP)和三功能集成包装(triple-functional integrated packaging,TFIP),将葡萄进行DFIP和TFIP包装,以没有任何包装的葡萄为对照,研究其在常温(25℃)贮藏条件下的品质变化。通过商业价值综合分数评价,DFIP和TFIP中的葡萄分别可贮存4 d和8 d,对照组只能贮存2 d。与对照组相比,DFIP和TFIP可有效维持葡萄硬度、可溶性固形物质量分数与VC含量,降低葡萄水分损失率。而且,TFIP中缓释的1-甲基环丙烯可减缓果梗的褐变。这表明多功能集成保鲜包装有利于延长葡萄的货架期。
Dual-functional integrated packaging(DFIP)and triple-functional integrated packaging(TFIP)consisting of two and three functional films,respectively were applied to‘Kyoho’table grapes,and quality changes were monitored during storage at room temperature(25℃).Unpackaged grapes were used as a control.The results showed that through comprehensive evaluation of commercial value,the shelf life of the grapes with DFIP and TFIP was 4 and 8 d,respectively,while the control could be stored for only 2 d.DFIP and TFIP effectively maintained high contents of total soluble solids(TSS)and vitamin C and good berry firmness and reduced water loss compared with the control group.Moreover,sustained release of 1-methylcyclopropene from TFIP delayed stem browning.These results suggested that the multi-functional integrated packaging can extend the shelf life of table grapes.
