Fuente: WIPO "tomato" A method for controlling the ripening degree of a fruit/vegetable, the method including bringing a coated fruit/vegetable having a coating film formed on a surface, into contact with a ripening degree controlling substance, wherein the coating film contains a surfactant containing a long-chain aliphatic group in its chemical structure, and has a ratio of a total endothermic peak area A1 in a range of 0° C. or higher and 40° C. or lower to a total endothermic peak area A2 at 0° C. or higher and 80° C. or lower of 50% or less in differential scanning calorimetry with a measurement temperature range of 0° C. or higher. According to the present invention, it is possible to provide a method for controlling the ripening degree of a fruit/vegetable as necessary while keeping freshness of the fruit/vegetable.
