In general, pesticides are essential commodities of modern agriculture used to remove harmful organisms such as harmful germs, pests, and weeds, or to prevent damage from crops and fruits. As a result, the demand for agricultural products increases with the demand of agricultural products, and the amount of pesticides used is increasing year by year. Currently, about 850 kinds of pesticides are used in Korea, and pesticides and herbicides, which are organophosphorus compounds, are mainly used.

Due to the increased use of pesticides, problems caused by pesticides remaining in fruits and vegetables are also increasing. In addition, in recent years, the import and openness of agricultural products is successive, and various fungicides and preservatives are excessively used in order to maintain the freshness of imported agricultural products, and thus, the fear of pesticide residues and harmful substances of agricultural products is realized.

In order to remove the residual pesticides of such agricultural products, a method of washing fruits and vegetables using synthetic detergents is generally used. When cleaning fruits and vegetables using synthetic detergents, synthetic detergents may remain on the surface of agricultural products. Not only is there a concern that secondary water pollution occurs due to the compound contained in the synthetic detergent.

Accordingly, cleaning systems and cleaning methods using ultraviolet rays, ozone gas, and ultrasonic waves have been proposed to clean fruits and vegetables without using a synthetic detergent. However, the above apparatus and methods have a problem in that the technology is complicated and the installation cost is expensive, so it is difficult to be practical. In addition, the method of using ultraviolet rays is suitable for air sterilization but not for sterilizing water. The method of using ozone gas has to properly control the amount of ozone used because ozone is harmful to the human body. There are many difficulties in maintaining, and the method using only ultrasonic waves has a disadvantage of low sterilization efficiency.
