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., Se evaluó el efecto de la aplicación de 1-metilciclopropeno 1-MCP, un agente antagonista a la acción del etileno -el 1-metilciclopropeno es utilizado para prolongar la vida útil del fruto de granadilla común-, almacenado a 27 ± 2 °C y 76 ± 2% de HR. Se evaluaron propiedades físicas como pérdidas de peso y cambios de dureza de la corteza; propiedades químicas como pH, acidez titulable y sólidos solubles; y propiedades organolépticas como cambios de color. Se aplicaron tres concentraciones de 1-MCP: 200, 400 y 600 mg-l y tres tiempos de exposición: 15, segundos 30 segundos y 60 segundos. Los resultados sugieren que la aplicación de 600 mg-l de 1-MCP y 60 segundos de exposición conserva la granadilla común durante 15 días a 27 ± 2 °C y 76 ± 2% de HR.
