Shelf life extension of the sweet passion fruit is helpful for its marketing, since it is positioned in the international market as a gourmet fruit. In this work the effect of applying an antagonistic agent to the ethylene action was evaluated, 1- methylcyclopropene (1-MCP) was used to prolonged shelf life of sweet passion fruit, stored of 27 ± 2 °C and 76 ± 2% RH. Physical properties as weight loss, firmness loss and color changes were evaluated, together with chemical properties such as pH, acidity and soluble solids and sensory analysis. Three concentrations of 1-MCP: 200, 400 and 600 mg/l with three exposure times: 15, 30 and 60 seconds were applied. The results suggest that application of 600 mg/l of 1-MCP for 60 seconds of exposure preserves the fruit during 15 days at 27 ± 2°C and 76 ± 2% of HR.
