Problems solved by technology

However, the sterilizing range of ultraviolet rays is limited to the part that can be irradiated by ultraviolet rays, and it cannot sterilize the rear side and interior of objects, and the ultraviolet radiation intensity of ultraviolet lamps is gradually weakened. Materials such as peanut kernels and peanut oil cannot completely remove the aflatoxin in the material
[0012] At present, there are no invention patents and research reports that are identical to the patent application of the present invention and are specifically aimed at the degradation method of aflatoxin in peanut products.

Abstract

The invention discloses a degradation method of aflatoxin, which includes treating the material containing aflatoxin through the combination role ultraviolet light, microwave and light wave, that is degradating aflatoxin on the surface of material through the role of ultraviolet light, which is enhanced by light wave, pyrolysising aflatoxin in the material through the role of microwave, which allows the surface of the material and the inner part of the aflatoxin to absorb energy from the outside to the inside and at the same time pyrolysising and removing it. The invention is easy to operate and has good degradation effect, which is suitable for degradating aflatoxin in peanut, peanut kernel, peanut oil, coix seed crop, coix seed rice, corn or feed and controlling aflatoxin content, and has high application valve and market potential.

Description

technical field [0001] The invention relates to the field of food processing and preservation, in particular to a method for degrading aflatoxin. Background technique [0002] Peanut is second only to rapeseed in the planting area of ​​my country's oil crops, but the total output, yield and export volume rank first. my country is the largest peanut producer in the world, and its total annual peanut production continues to exceed that of India and ranks first in the world. Now my country's peanut planting area is greater than 5025khm 2 , the total output is greater than 15006kt, accounting for more than 44.04% of the world's total output. [0003] At the same time, my country is one of the largest peanut exporters in the world, with an annual export volume of more than 400kt. It is my country's main export-earning agricultural product and has strong competitiveness in the international market. It is mainly exported to the European Union, Japan, Southeast Asia and the Middle...
