PROBLEM TO BE SOLVED: To provide a method for hydrophilizing a matter adhered to a food surface that can easily wash out an adhered matter with low hydrophilicity, such as wax, with water.SOLUTION: The method includes supplying water to an atomization electrode of an electrostatic atomization device A and applying a voltage to the supplied water to generate charged atomized water of a nano meter size. The charged atomized water is sprayed, for a predetermined period of time, to food that is an object 1 to be treated having a surface to which the adhered matter 15 is applied, thereby improving the hydrophilic property of the adhered matter 15. This allows the adhered matter 15 to be easily washed out in subsequent washing with water.COPYRIGHT: (C)2013,JPO&INPIT【課題】ワックス等の親水性の低い付着物を、水洗いによって簡単に洗い流すことを可能とする食物表面付着物の親水化方法を提供する。【解決手段】静電霧化装置Aの霧化電極に水を供給し、供給された前記水に電圧を印加してナノメータサイズの帯電微粒子水を発生させる。この帯電微粒子水を、表面に付着物15が塗布された処理対象物1である食物に所定時間噴霧することで、付着物15の親水性を向上させる。これにより、その後の水洗いによって付着物15を簡単に洗い落とすことが可能となる。【選択図】図1
