Abstract
Mangoes are perishable fruit that lose their fruit firmness and weight rapidly during harvest, postharvest treatment, and transport.
Thai fresh mangoes are usually treated with ionizing radiations as a phytosanitary treatment before being exported to overseas markets.
In this study, the effect of 1-methylcyclopropene (1-MCP) on mango fruit quality and their shelf-life was investigated after irradiation.
The fruit was treated individually through fumigation with a 1-MCP via different at 500 and 1,000 ppb for 12 and 24 h at 25°C then stored at 13-15°C for 24 days.
It was found that irradiated mango treated with 1-MCP at 500 and 1,000 ppb was more effective in maintaining quality on color, TSS/TA, fruit firmness, respiration rate, and ethylene production.
Acceptable fruit after 24 days was higher than 80% in treated fruit with 1-MCP treatments at 500 and 1,000 ppb.
Ripening of 1-MCP treated fruits was significantly delayed compared with non-treated fruit, and successfully extended the postharvest life of of Nam Doc Mai Si Thong mango.
These results demonstrate that 1-MCP application after irradiation is a useful postharvest method for the preservation of mango fruit for long distances freight.
