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
The invention belongs to mechanical degradation aflatoxin field, be specifically related to a kind of device and application thereof of plasma degradation aflatoxin.
Background technology
Aspergillus flavus (Aspergillus flavus) is a kind of mushroom that very easily is present in the agricultural product such as peanut, corn, wheat class, paddy., not only cause by agricultural product corruption after receiving infection by Aspergillus flavus easily; And; (Aflatoxin is one of material the strongest in the chemical carcinogen of finding at present AFT) to the metabolite aflatoxin that aspergillus flavus produces in growth course, mainly damages liver function and strong carcinogenic, teratogenesis, mutagenesis are arranged; Can bring out liver cancer, osteocarcinoma, kidney, the carcinoma of the rectum, breast cancer, oophoroma etc.; The serious threat human beings'health is classified as the strongest known carcinogenic substance by The World Health Organization (WHO), receives the extensive concern of countries in the world.At present, for ensureing human food security, each country is to the check increasingly stringent of aflatoxin.States such as Singapore, Malaysia, Denmark require must not detect aflatoxin in import peanut and the goods; States such as Britain, Sweden, Holland, Italy, Poland, Australia require aflatoxin content must not be higher than 5 μ g/kg; Japan's requirement must not be higher than 10 μ g/kg; Canada, the U.S. and most country in Southeast Asia must not require and be higher than 20 μ g/kg, and the export of farm produce " threshold " improves thus.Particularly in recent years, China's Agricultural outlet suffers the aflatoxin technical barrier that exceeds standard repeatly, brings enormous economic loss for the producer and enterprise.
The growth of mould is lower to environment requirement, only needs the carbon of minute quantity and nitrogen just can grow, breed, produce poison, can pollute agricultural product and produce toxin in links such as plantation, storing, processing.Since the sixties in last century; Removal methods to aflatoxin has been carried out big quantity research; Mostly report was to adopt chemical reagent to remove poison in the past; Yet investigation is found after deliberation, and there are many defectives in most of chemical treatment, as must under extreme temperature and pressure condition, carry out, the formation of poisonous residue and to the destruction of product nutrition, sense organ and functional characteristic etc.With the biochemical method of preventing and treating also because higher and technological former of cost thereby can not use energetically and promote.
Summary of the invention
The chemical agent that exists to chemical treatment method in the prior art pollutes, destroys the nutritional labeling of product; And the processing cost that biological control method exists is crossed problems such as height; The invention provides a kind of device and application thereof of plasma degradation aflatoxin; Device according to the invention can be handled aflatoxin efficiently, fast, safely based on physics plasma method material handling, reaches the purpose of aflatoxin degradation; Can realize not having medicament fumigating, have effects such as pollution-free, green environmental protection, high-quality, the low management cost of maintenance and low technical threshold.
In order to reach the purpose that solves the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of device of plasma degradation aflatoxin; It comprises plasma emitters, water cooler, plasma generator and processor; Said plasma emitters is connected with water cooler; Said water cooler is connected with plasma generator; In said plasma generator, be provided with the plasma electrode that storehouse and scalable spacing take place plasma, be connected the vavuum pump of the interior gas density of the external adjusting device of said processor through tube connector between said plasma generator and the said processor.
Further improvement to technical scheme: the operating power of said plasma emitters is 100-200W.
Further improvement to technical scheme: be 30-90s the action time of said plasma emitters.
Further improvement to technical scheme: the pole span scope of said plasma electrode is 2-6cm.
The present invention also provides the application in the aflatoxin in the degraded material of described device.
Further improvement to technical scheme: said material is peanut, corn, wheat class, paddy.
Compared with prior art; Advantage of the present invention and good effect are: the present invention utilizes the plasma treatment aflatoxin; Save the chemical treating process that possibly bring food security hidden danger, kept the quality of raw material effectively, reduced managing risk and cost; Realized the target of green aflatoxin degradation, degradation rate can reach more than 50%; And device according to the invention is simple to operate, and technical threshold is low; The present invention has greatly reduced processing cost, has reduced labour intensity.
After the advantages specific embodiment of the present invention, other characteristics of the present invention and advantage will become clearer.
