多功能集成保鲜包装设计在巨峰葡萄中的应用

摘要/Abstract

摘要： 目的延长巨峰葡萄在常温（25 ℃）条件下的货架期。方法以收获后未经任何处理的巨峰葡萄为实验对象，然后立即装入特殊结构的自制包装，其包装由两片或三片功能薄膜组成。这些功能薄膜包括一种透湿薄膜、一种透氧薄膜和一种1-甲基环丙烯（1-MCP）缓释薄膜。功能薄膜中的两种或三种被相互拼接粘合（无层叠）形成片状矩形膜，然后将矩形膜对折并粘合制成双功能集成包装（double functions integrated packaging, DFIP）或三功能集成包装(three functions integrated packaging, TFIP)。结果通过商业价值综合分数评价，DFIP和TFIP中的葡萄在25℃下分别可储存4天和8天，对照组只能储存2天。DFIP和TFIP有效的维持了葡萄中可溶性固形物（TSS）与维生素C（VC）含量，且水分损失仅仅占对照组的1/6左右，硬度提高24- 38％。结论 TFIP中释放的1-MCP有效的抑制了果梗褐变。TFIP形成了一个CO2浓度2-5％，O2浓度17-19％，相对湿度（RH）90-95％的被动改性气氛，有利于减缓葡萄的呼吸强度，延缓葡萄的成熟，延长葡萄的货架期。

Abstract: In order to extend the shelf life of Kyoho table grapes at room temperature (25 ℃), we used the Kyoho table grapes of non-treatment after harvest as the experimental object and then immediately put it into self-made packaging of special structure which consisting of two or three active films. These active films include a moisture permeable film, oxygen permeable membrane and a function flm with slow-releasing 1-MCP. Two or three active films are adhered (without multi-laminated) to form a piece film. Then the rectangular film is folded and bonded into double functions integrated packaging (DFIP) or three functions integrated packaging (TFIP). The results showed that the grapes in DFIP and TFIP were stored for 4 days and 8 days at 25 ℃, respectively, and the control group could only be stored for 2 days. DFIP and TFIP effectively maintained the content of soluble solids (TSS) and vitamin C (VC) in grapes. Water loss only accounted for 1/6 of the control group and hardness increased by 24 - 38%. Especially the release of 1-MCP in TFIP inhibited rachis browning. TFIP formed a passive modification atmosphere with a CO2 concentration of 2-5%, O2 concentration of 17-19% and relative humidity (RH) of 90-95%, which was beneficial to slow down the grape's respiration intensity, delay the ripening and prolong the shelf life of grapes.

Key words: Kyoho Table Grapes, double functions integrated packaging（DFIP）, three functions integrated packaging（TFIP）, vitamin C（VC）, shelf life
