Device for degrading aflatoxin by using plasma and application of device

Abstract

The invention provides a device for degrading aflatoxin by using plasma. The device comprises a plasma emitter, a water cooler, a plasma generator and a processor, wherein the plasma emitter is connected with the water cooler; the water cooler is connected with the plasma generator; a plasma generating storehouse and a plasma electrode capable of adjusting pitch are arranged in the plasma generator; the plasma generator is connected with the processor through a connecting pipe; and the processor is externally connected with a vacuum pump for adjusting density of gas in the device. Based on physical treatment, the device can degrade the aflatoxin in agricultural products efficiently, quickly and safely. According to experimental verification, the device has the obvious effect of degrading the aflatoxin; the degrading rate can reach over 50 percent; and the problems of pollution to chemical agents, damage to nutrients, sense and functional characteristics of products, overhigh cost and the like in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of physical degradation of aflatoxin, and in particular relates to a device for plasma degradation of aflatoxin and its application. Background technique [0002] Aspergillus flavus is a fungus that easily exists in agricultural products such as peanuts, corn, wheat, and rice. When agricultural products are infected by Aspergillus flavus, it is not only easy to cause spoilage, but also the metabolite Aflatoxin (AFT) produced by Aspergillus flavus during growth is one of the strongest chemical carcinogens found so far, which mainly damages the liver. Function and strong carcinogenic, teratogenic, mutagenic effects, can induce liver cancer, bone cancer, kidney cancer, rectal cancer, breast cancer, ovarian cancer, etc., seriously threatening human health, has been listed by the World Health Organization (WHO) as a The strongest known carcinogen has attracted widespread attention from all over the world. At present, in ...
