摘　　要：以落粒率、腐烂率和失重率作为鲜食葡萄损耗的评价指标,系统分析了鲜食葡萄保鲜技术效果的形成过程,应用多元回归方法综合评估了目前应用比较广泛的6种保鲜技术以及冰温环境对鲜食葡萄的保鲜效果。结果表明:气调、保鲜膜、SO2气态处理、CT-2保鲜剂、简化包保鲜剂、1-MCP气态处理以及冰温均能有效抑制果实损耗,其中气调、冰温环境和2种保鲜剂对鲜食葡萄的3个损耗指标有显著的抑制效果;气调、保鲜剂和保鲜膜对果实腐烂率和失重率的影响随时间增加而逐渐增强,其中保鲜膜的作用效果十分微弱;保鲜剂对果实质量损耗的浓度效应十分明显,浓度过大会损伤果实组织、增加损耗,而与SO2气态处理的联合使用会增强对果实损耗的降低作用;1-MCP主要在果实腐烂率的控制方面有较好效果。The effect of preservation technologies on table grape was systematically analyzed and effect of six preservation technologies and controlled freezing-point storage was comprehensively compared and evaluated in the aspect of three indicators of the loss of table grape, i. e. , berry shatter, rotting rate and weight loss based on multiple regression. The evaluation results showed that controlled atmosphere storage, preservative film, 1-MCP, SO2 fumigation, the fresh-keeping agent CT-2 and simplified packet and controlled freezing-point storage can effectively reduce the loss of the fruit. The influence of controlled atmosphere storage, S02 and controlled freezing-point storage was more obvious in decreasing the three indicators of the loss of table grape. Controlled atmosphere storage and two fresh-keeping agents＇ impacts on the rate of rotting and weight loss of table grape were enhanced with the course of time. In addition, the loss of fruit would be increased by using overdose of fresh-keeping agents, while the preservatives on the fruit can be enhanced by SO2. The preservation performance of preservative film would be seen gradually over time but the effect was very weak; 1-MCP has few performance on fruit preservation but it can achieve better performance in rotting rate control of table grape.
