Preparation and application of plasma active water

Abstract

The invention discloses a plasma active water preparation device which is characterized by comprising a water preparation reactor and a cleaning container, and the water preparation reactor comprisesa power supply, a reaction chamber, a water storage container, an air inlet pipe and a sliding arc; the water storage container and the cleaning container are connected through a circulating water path; one end of the air inlet pipe is connected with the reaction chamber, and the other end of the air inlet pipe is connected with an external gas source; the power supply is connected with the reaction chamber, two parallel electrodes are arranged in the reaction chamber, and external gas is introduced into the reaction chamber for discharging between the two electrodes to form plasma; the sliding arc is moved out of the lower end of the reaction chamber under the driving of external gas, the distance between the sliding arc and the liquid level of the water storage container is maintained tobe 1-50 mm, and plasma active water is prepared; the plasma active water can be used for cleaning various fruit and vegetable fresh foods or agricultural products including cherry tomatoes and the like, and the storage and fresh-keeping period can be effectively prolonged.

Description

technical field [0001] The invention belongs to the field of storage and preservation of agricultural products, and in particular relates to the preparation of plasma active water. Background technique [0002] An important reason for the rot of fresh fruit and vegetable products is the presence of various food-borne harmful microorganisms on the surface. General sterilization methods, such as high-temperature sterilization, high-temperature instant sterilization, etc., will destroy nutrients through temperature or steam sterilization, and are not suitable for For the cleaning of fresh fruits and vegetables, chemical sterilization methods such as hypochlorous acid, ozone water, and hydrogen peroxide have certain chemical residues and pollution, and are not suitable for cleaning and disinfection of fresh fruits and vegetables. Therefore, the best sterilization methods for fresh fruits and vegetables are physical sterilization methods, such as ultra-high pressure sterilization...

Problems solved by technology

[0002] An important reason for the rot of fresh fruit and vegetable products is the presence of various food-borne harmful microorganisms on the surface. General sterilization methods, such as high-temperature sterilization, high-temperature instant sterilization, etc., will destroy nutrients through temperature or steam sterilization, and are not suitable for Cleaning of fresh fruits and vegetables, but chemical sterilization methods such as hypochlorous acid, ozone water, and hydrogen peroxide have certain chemical residues and pollution, and are not suitable for cleaning and disinfection of fresh fruits and vegetables

Therefore, the best sterilization methods for fresh fruits and vegetables are physical sterilization methods, such as ultra-high pressure sterilization, high-voltage electric field sterilization, and radiation sterilization. Quality and flavor, less application in fruit and vegetable preservation
