DUSSAN SARRIA, Saúl; SERNA COCK, Liliana  e  PERENGUEZ CUARAN, ángela María. Effect of 1-Metyilciclopropene application on the physical, chemical and organoleptic properties of the sweet passion fruit. Acta Agron. [online]. 2011, vol.60, n.3, pp.236-243. ISSN 0120-2812.

To extend the shelf life of the sweet passion fruit is helpful for marketing of the fruit, 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, the 1- methylcyclopropene (1-MCP) for the prolongation of shelf life of sweet passion fruit, stored of 27 ± 2 °C and 76 ± 2% RH. Physical properties were evaluated as weight loss, firmness loss and color changes, chemical properties as pH, acidity and soluble solids and sensory analysis. Three concentrations of 1-MCP were applied: 200, 400 and 600 mg%lt and three exposure times: 15, 30 and 60 seconds. The results suggest than application of 600 mg%lt of 1-MCP and 60 seconds exposure it maintains the fruit during 15 days to 27 ± 2°C and 76 ± 2% of HR.
