摘要
樱桃番茄口味鲜美、营养丰富,但采后不耐贮藏,在常温条件下货架期较短.因此,探索一种适用于樱桃番茄的保鲜方式以延长其在常温条件下的货架期,具有重大的经济价值和现实意义.该试验研究了不同浓度的1-甲基环丙烯(1-Methylcyclopropene,1-MCP)单独处理及与不同浓度茶多酚(Tea polyphenols,TP)溶液结合处理对樱桃番茄采后品质的影响.结果表明:不同浓度1-MCP处理(0.4、0.6、0.8、1.0、1.2 μL/L)对樱桃番茄均有一定的保鲜效果,其中,0.8 μL/L 1-MCP处理的保鲜效果较好,到贮藏结束时,0.8μL/L1-MCP处理组的维生素C含量、可溶性固形物含量、果实硬度分别是对照组(CK)的2.36、1.1、1.55倍,失重率和腐败率分别是CK的80.4％、71.4％;与单一的1-MCP处理组相比,1-MCP结合TP处理(1-MCP+TP)对于果实的保鲜效果更好,其中,1-MCP+0.75％TP处理的保鲜效果最好,到贮藏结束时(第10天),1-MCP+0.75％TP处理组果实的可溶性固形物含量、失重率、腐烂率分别是1-MCP处理的1.14倍、56.67％、58.33％.因此,1-MCP+0.75％TP处理可作为一种在常温条件对樱桃番茄起到保鲜作用的新处理方式.
Abstract
Cherry tomatoes are delicious and nutritious,but they are not storable after harvest and have a short shelf life at room temperature.Therefore,it is of great economic value and practical significance to explore a fresh-keeping method suitable for cherry tomatoes to prolong their shelf life at room temperature.The effects of different concentrations of 1-methylcyclopropene(1-MCP)alone and combined with different concentrations of tea polyphenols(TP)solution on postharvest quality of cherry tomatoes were studied.The results showed that different concentrations of 1-MCP treatment(0.4,0.6,0.8,1.0,1.2μL/L)had certain fresh-keeping effects on cherry tomatoes,among which 0.8 μL/L 1-MCP treatment had a better fresh-keeping effect.By the end of storage,the content of vitamin C,soluble solids,fruit hardness,weight loss and rot rate of 0.8 μL/L 1-MCP treatment group were 2.36,1.1,1.55 times and 80.4％,71.4％of those in CK,respectively.Compared with the single 1-MCP treatment group,1-MCP combined with TP treatment(1-MCP+TP)has a better fresh-keeping effect,among which 1-MCP+0.75％TP treatment has the best fresh-keeping effect.By the end of storage(10th day),the soluble solid content,weight loss rate and rot rate of 1-MCP+0.75％TP were 1.14 times,56.67％and 58.33％compared with the only 1-MCP treatment,respectively.Therefore,1-MCP+0.75％TP treatment can be used as a new way to keep cherry tomatoes fresh at room temperature.
