    摘要:

    以落粒率、腐爛率和失重率作為鮮食葡萄損耗的評價指標,系統(tǒng)分析了鮮食葡萄保鮮技術效果的形成過程,應用多元回歸方法綜合評估了目前應用比較廣泛的6種保鮮技術以及冰溫環(huán)境對鮮食葡萄的保鮮效果。結果表明:氣調、保鮮膜、SO2氣態(tài)處理、CT2保鮮劑、簡化包保鮮劑、1-MCP氣態(tài)處理以及冰溫均能有效抑制果實損耗,其中氣調、冰溫環(huán)境和2種保鮮劑對鮮食葡萄的3個損耗指標有顯著的抑制效果;氣調、保鮮劑和保鮮膜對果實腐爛率和失重率的影響隨時間增加而逐漸增強,其中保鮮膜的作用效果十分微弱;保鮮劑對果實質量損耗的濃度效應十分明顯,濃度過大會損傷果實組織、增加損耗,而與SO2氣態(tài)處理的聯(lián)合使用會增強對果實損耗的降低作用;1-MCP主要在果實腐爛率的控制方面有較好效果。

    Abstract:

    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 CT2 and simplified packet and controlled freezing-point storage can effectively reduce the loss of the fruit. The influence of controlled atmosphere storage, SO2 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.
