摘要
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, headspaee 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.
