| Abstract:
Mangoes (Mangifera indica L.) are tropical fruit that have highly potential in Thai economic because of a number of exporting fruit each year. Mangoes are classified as climacteric fruit that respond to ethylene and cause ripening and deterioration on quality and storage life of the mangoes. A study of the effect of 1-MCP, an ethylene action inhibitor was investigated. ‘Nam Dokmai’ mangoes were fumigated with 250 500 and 1000 ppb 1-MCP for 24 hours at 25ºC and stored at 20ºC. Mangoes treated with 250 ppb 1-MCP showed the most effective to delay firmness until the end of storage. While treatments with higher concentrations of 1-MCP (500 and 1000 ppb) resulted in lower respiration rate and ethylene production, L* and b* values tended to increase during storage. Color changes were delayed in mangoes treated with 1-MCP. 1-MCP treatment also prolonged the shelf life of mango to 15 days of storage at 20ºC. | |
