‘Mutiara’ guava fruit is one of two leading guava cultivars sold in Indonesian markets. Its thin skin and climacteric-typed respiration shorten its shelf-life due to high transpiration and respiration rates. Eventhough 2.5% chitosan was proven to lengthen its shelf-life, the effect of ethylene trapped under chitosan coating needs to be blocked in order to increase its coating affectivity. This research was aimed at studying the effects of 1-methylchyclopropane (1-MCP) and its combination with 2.5% chitosan on fruit shelf-life and qualities of ‘Mutiara’ guava. This work was conducted during September-October 2013. A randomized complete block design of two factors was used. The first factor was 1-MCP gassing (control and 1-MCP), and the second one was chitosan (control and 2.5% chitosan). 1-MCP gas was developed by diluting 0.5 g 1-MCP powder into 30 ml of water. The results showed that 1-MCP as a sole application did not significantly influence fruit shelf-life and qualities through fruit firmness, weight loss, soluble solid, and acidity compared to treatments of control and chitosan alone, but it showed more profound effects in increasing shelf-life and maintaining ‘Mutiara’ guava fruit qualities when it was applied in a combination with 2.5% chitosan coating.
