PURPOSE:To safely and economically promote the reduction of acid and increase of sugar content in fruit or fruit vegetable and to improve commercial value of the fruit, etc., by irradiating the fruit, etc., with electromagnetic wave. CONSTITUTION:The fruit or fruit vegetable to be treated is optionally put into a conventional container made of an electromagnetic wave-transmitting material and irradiated with electromagnetic wave having wavelength of about 1mum-1m, preferably 10mum-1cm. Conventional radiation sources such as infrared lamp, far infrared heater, sheathed heater, magnetron, radio wave transmission tube, etc., may be used as the radiation source singly or in combination. The irradiation time is properly determined according to temperature, kind of the fruit or fruit vegetable, kind of radiation source, intensity of radiation, method for irradiation, etc. The fruit, etc., may be irradiated just after harvest, during storage or during transportation.
