为了延长葡萄的保存期,文中研究了室温条件下((23 ±1) ℃),1-MCP 释放垫和SO2 杀菌袋对存储期内葡萄品质的影响。将裸放葡萄(对照组)和SO2 杀菌袋包装葡萄(K 组)作为比较组,含有1-MCP 释放垫的杀菌包装袋包装葡萄作为研究组(K+MCP 组),主要测定了葡萄的失重、褐变、硬度、可溶性固形物、顶空气体浓度和感官评价等参数。由于葡萄在存储期内出现失水和茎褐变,对照组和K 组的保质期分别为2 d 和4 d,而K+MCP 组能把葡萄保质期延长到8 d。结果表明,SO2 杀菌袋和1-MCP 释放垫的结合使用可以延长葡萄在室温下的贮存质量及保质期。

Influence of 1-methylcyclopropene (1-MCP) generating pads and sulfur dioxide (SO2 ) germicidal bags on quality of Kyoho grapes in storage was studied. The unpacked grape (control group), SO2 germicidal bag-packed grapes (K group), and (K+MCP) group containing SO2 and 1-MCP were studied through determination of weight loss, stalk browning, firmness, total soluble solids, headspace gas concentrations, and sensory evaluation index. The experiment showed that the shelf-lives of the control group and the K group were 2 and 4 d, respectively, limited by severe dehydration and stem browning; in contrast, the germicidal bags containing 1-MCP pads were able to effectively extend the grapes'shelf-life to 8 days. It was concluded that the combined application of SO2 germicidal and 1-MCP treatments can extend shelf-life of grape at room temperature.
