A method of washing the fruit surface by successively spraying hot water, wash water containing foreign material removing agents and carbonates and cold water on the fruit surface containing the curved portion of fruit is provided to effectively remove soils, microorganisms, insect pests present on the fruit surface and pollutants which are firmly attached to the pericarp without causing damage and thus increases the commercial value. The fruit surface containing the curved portion of fruit is sprayed with hot water of 50 to 55deg.C at a pressure of 3 to 20kg/cm^2 for 3 to 30sec, is then sprayed with wash water containing foreign material removing agents and carbonates, and finally, is sprayed with cold water at a pressure of 1 to 5kg/cm^2 for 3 to 10sec to remove the removing agents and carbonates. The foreign material removing agent is selected from zeolite, sellaite, bentonite and activated clay. The carbonates are sodium carbonate or sodium bicarbonate. |
