Banana passion fruit or curuba (Passiflora tripartita var. mollissima) is an exotic fruit liana with fruits of high antioxidant capacity. Its fruits have medicinal, nutritional and industrial properties that make it a product with high nutraceutical potential. This fruit is perishable during postharvest, which is a limiting factor for its conservation. An alternative method for extending the shelf life of fruit postharvest is the use of 1-methylcyclopropene (1-MCP), which inhibits the action of ethylene, delaying the ripening process in fruits and, together with low temperatures, preserves curuba for a longer period without altering its nutritional composition. The effect of the application of 1-MCP and temperature on the quality of curuba fruits was determined. A completely randomized design with four treatments was used: control (14°C), temperature 4°C, 3 mg L-1 1- MCP+14°C, and 3 mg L-1 1-MCP+4°C. The variables evaluated in fruits were color, weight loss, respiration, firmness, total soluble solids, and total titratable acidity. The fruits exposed to the 4°C or 3 mg L-1 1-MCP+4°C treatments had higher firmness and total soluble solids, lower weight loss, and lower color index and titratable acidity with a storage duration of 29 d. The fruits subjected to the 3 mg L-1 1-MCP+4°C treatment showed lower weight loss than in the other treatments. The use of 1-MCP together with low temperatures prolongs the postharvest life of curuba.
