This work aimed to evaluate the effect of different concentrations of 1-MCP on the ripening process of sapodilla. Fruits were harvested at the physiologically mature stage and treated with 0, 300 and 600 nL.L-1 dosages of 1-MCP for 12 hours in hermetically closed chambers at 25 ± 2ºC and 70 ± 5% R.H.. After the 12 h 1-MCP treatment, the fruits were stored for 23 days under the same conditions of temperature and humidity. The parameters analyzed for postharvest quality were: weight loss, external appearance, firmness, pulp color, total titrable acidity, total soluble solids and total soluble sugar content. In sapodilla, 1-MCP delays ripening and prolongs the postharvest shelf life and the 300 nL.L-1 of 1-MCP dosage showed the best results extending the postharvest life of sapodilla in 6 days.
