Abstract:
This paper describes the relationship between the circulation environment and grape quality to understand the changes of grape quality under different temperature and humidity and transport condition. The measurement parameters include weight loss rate, sugar content, hardness and Vitamin C content and so on. The experiments showed that the temperature had important effects on grape quality, the weight loss rate of the grapes was 3.85 percent and the hardness loss rate was 6.67 percent to storage for ten days at zero degrees centigrade, and then the changes of grape quality tended to be stable. However the weight loss rate was 5.03 percent and the hardness loss rate was 32.17 percent to storage for only six days at twenty degrees centigrade, after that the grape quality was sharply reduced, and the grapes had been rotten. It can be conclude that low temperature can greatly reduce the grape respiratory rate and metabolic rate, and low temperature and high humidity was suitable for grapes to storage. The vibration was one of the main causes of grape damage during transport, the grapes on higher layers get more damage than below layers. In order to prevent the grape damage in the process of transport and storage, the appropriate derogation packaging was necessary, which can reduce the damage and ensure the safety of the grape. This paper provided the reference for understanding the damage mechanism of grape and designing derogation packaging.
