Abstract

The invention relates to a method for irradiation degradation of aflatoxin in cypress kernels. Before irradiation, the method needs to carry out crude product treatment on the cypress kernels to be treated, that is, the surface of cypress kernels is uniformly coated with stabilizer The porous corn starch layer is then irradiated with 60Co-γ rays at a radiation dose of 1-10 kGy. Finally, the irradiated cypress kernels are repeatedly soaked and washed with ethanol, and the alkali lignin, corn porous starch, and stabilizer on the surface of the cypress kernels are cleaned, and then dried. Aflatoxin. The results show that this method can effectively remove the aflatoxin contamination of the cypress kernels, and at the same time minimize the loss of nutrients in the cypress kernels, so that the levels of fatty acids and proteins in the oil-rich cypress kernels are almost the same before and after irradiation. Changes occur, and do not involve chemical reagents, there is no residue problem, and food safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of food processing and preservation, in particular to a radiation degradation method for aflatoxin in cypress kernels. Background technique [0002] Aflatoxin is a group of difuranocoumarin metabolites with similar structures produced by Aspergillus flavus and Aspergillus parasiticus. The common ones are aflatoxin B1, B2, G1, G2, etc., which are recognized carcinogens in the world. Among them, aflatoxin Aspergillus toxin B1 is currently the most powerful carcinogen known in the world, and is listed as a class 1A carcinogen by WHO, which is extremely harmful to human health. The pure product of aflatoxin is colorless crystal, insoluble in water and easily soluble in oil. Almost every kind of fruit grain or fruit grain product may grow aflatoxin under certain temperature and humidity. The most important aflatoxin carriers are peanuts and a series of other nut kernels, as well as corn, rice, soybeans, and gra...
