摘要
脆李果实采后分别经PE、PVC薄膜包装,在0℃冷藏一段时间后置于25℃环境下进行货架贮藏,在贮藏期、货架期分别或复合进行1-MCP处理脆李果实,研究不同材料包装对脆李果实硬度和可溶性固形物含量的影响。结果表明,不同薄膜包装均具有良好的气调效果,其中PVC比PE包装能更有效地提高CO_2和降低O_2百分含量,延缓货架期果实硬度下降,保持较高的可溶性固形物含量;货架期1-MCP处理可以维持最高的脆李硬度和较高的可溶性固形物含量。
In this experiment, the effect of modified atmosphere package(PE, PVC) and 1-MCP treatment on the quality related to physiological indexes such as firmness, soluble solid content(SSC) of postharvest crisp plum were investigated during cold storage(0 ℃) and shelf life(25 ℃). The results showed that both film packaging had good air conditioning effect. PVC package could effectively increase CO2 content and decrease O2 content during storage compared with PE package, delay the decline of firmness during shelf life and maintain SSC at a high level, and1-MCP treatment could keep the highest firmness and higher SSC during shelf life.
