Abstract
Blueberry is one of the thinnest exocarp fruits in the world, which is difficult to keep fresh due to the special structure of its skin. 1-Methlcyclopropene (1-MCP) is able to combine with ethylene(ETH) receptor. In this study we investigated the effect of 1-MCP on rotting rate, weight loss ratio, soluble sugar content, titratable acid content, antioxidant enzyme activities and malondialdehyde (MDA) content in blueberry (Vaccinium corymbosun ‘O Neal’ and ‘North Road’) under cold storage. 1-MCP reduced the rotting rate, weight loss ratio and MDA content, while keeping high-leveled stability in antioxidant enzyme activities, soluble sugar content and titratable acid content. These results showed the role of 1-MCP in alleviating the negative effects of blueberry and suggested that 1-MCP could be used as a preservative for keeping thin exocarp fruit in fresh.
