1-MCP application to prolong avocado shelflife

Abstract

1-MCP inhibits the activity of ethylene by blocking ethylene perception. For climacteric fruits like avocado, 1-MCP application is expected to delay the climacteric process, so as to extend shelf-life. In this study, 1-MCP application was made in two forms, gases with concentrations of 0, 0.2 and 0.4 μL L-1, and a solution with a concentration of 0, 0.3, and 0.6 μL L-1. The results showed that 1-MCP application in the form of gas or solution could extend avocado shelflife up to 2-2.5 times longer than control. Fruit could be stored for up to 16 days after treatment. 1-MCP treatment did not prevent the occurrence of fruit ripening, but delayed it. Exposure treatment with 1-MCP gas and the immersion solution of 1-MCP did not significantly change respiration rate, weight loss and color of the fruit flesh. As the technique of immersion in 1-MCP solution was easier to do, then this technique is recommended.
