| 摘 要： | 研究不同复合保鲜处理对‘夏黑’葡萄贮藏效果的影响,探索适合‘夏黑’葡萄的保鲜技术。以‘夏黑’葡萄为试材,用不同的保鲜剂焦亚硫酸钠(Na2S2O5)、1-甲基环丙烯(1-MCP)]和PP透气保鲜袋对材料进行8个组合处理,每个处理重复24穗,将处理后的‘夏黑’葡萄每3穗为一箱置于低温(0±1)℃、相对湿度90%~95%的环境中贮藏。以失重率、落果率、腐烂率、可溶性固形物含量、可滴定酸含量、可溶性糖含量、MDA含量、花色苷含量和果梗中叶绿素含量等作为测定指标,分析‘夏黑’葡萄在贮藏过程中果实品质的变化。结果显示,在整个贮藏期间,随着贮藏时间的延长,果穗的失重率、落果率、腐烂率、可溶性糖和花色苷的含量不断增加,可溶性固形物含量持续下降,可滴定酸和MDA的含量先增加再降低。不同复合保鲜处理中果实内在品质的变化趋势总体一致,但处理间存在显著差异,其中PP透气保鲜袋+1-MCP+Na2S2O5的复合处理与空白对照处理之间的差异最为明显。在贮藏112天后,PP透气保鲜袋+1-MCP+Na2S2O5的复合处理的‘夏黑’葡萄可溶性固形物的含量为15.18°Brix左右,较对照处理显著提高。同时其MDA、可溶性糖及花色苷的含量优于对照,说明这种复合处理的方式既可以保持果实色泽,又可以减缓葡萄果实的受自由基伤害的程度。因此PP透气保鲜袋+1-MCP+Na2S2O5的复合配方能够在一定程度上有效保持‘夏黑’葡萄果实品质,使其在贮藏112天后仍具有商品性。

| Abstract: | The paper aims to study the effects of different compound fresh-keeping treatments on the storage of grape and explore the preservation technology suitable for ‘Summer Black’ grape. ‘Summer Black’ grapes were treated with 8 different combinations of sodium pyrosulfite (Na2S2O5), 1-methylcypropene (1-MCP) and PP material breathable fresh bag. Each treatment was repeated with 24 clusters. The treated ‘Summer Black’ grapes were stored every three clusters in a box at low temperature (0±1)℃ and under relative humidity of 90%-95%. The weight loss rate, fruit drop rate, rot rate, soluble solid content, titratable content, soluble sugar content, MDA content, anthocyanin content, chlorophyll content in stem and etc. were used as indicators to analyze the quality change of grape fruits. During the storage period, with the extension of storage time, the weight loss rate, fruit drop rate, rot rate, soluble sugar and anthocyanin content of the clusters increased continuously, while soluble solid content decreased continuously, titratable acid and MDA content increased first and then decreased. The variation trend of fruit quality was the same under different treatments, but there were significant differences among the treatments, among which the difference between PP material breathable fresh bag+1-MCP+ Na2S2O5 treatment and blank control treatment was the most obvious. After 112 days of storage, the content of soluble solids in ‘Summer Black’ grape treated with PP material breathable fresh bag+1-MCP+ Na2S2O5 was about 15.18°Brix, which was significantly higher than that of the control. At the same time, the content of MDA, soluble sugar and anthocyanin were better than those of the control, indicating that this combination treatment could not only maintain the fruit color, but also slow down the degree of free radical damage of grape fruits. Therefore, the compound formula of PP material breathable fresh bag +1-MCP+ Na2S2O5 can effectively maintain the quality of ‘Summer Black’ grape fruit to a certain extent, so that the grape fruits can still be commercial after storage for 112 days. |
