1-Methylcyclopropene is used to slow down the ripening of fruit and maintain the freshness. Due to its reactivity, 1-MCP is traditionally mixed with cyclodextrin to form inclusion complex. We report here a strategy to facilitate the ease use of 1-MCP. 1-MCP was synthesized and cooled below its boiling point to be a liquid. Gases such as difluoroethane, trifluoroethane, tetrafluoroethane, propane, butane are compressed into liquid. Liquid 1-MCP is dissolved in mixture of liquid of fluorocarbons and hydrocarbons. The mixture of liquids contains 1%-2% (w %) of liquid 1-MCP. Liquid hydrocarbons such as propane and butane are used to promote the solubility of 1-MCP while fluorocarbons are used to help maintaining a safe composition. The mixture is stored in a can of gas duster. When the can is activated, gas flows out through the nozzle of gas duster can to treat the fruits and vegetables to help maintain their freshness.
