Abstract

The invention relates to an irradiation degradation method of aspergillus flavus in semen boitae. The irradiation degradation method of the aspergillus flavus in the semen boitae comprises the following steps of performing crude product treatment on semen boitae to be processed before irradiation, namely uniformly coating surface of the semen boitae with a porous corn starch layer containing a stabilizing agent; then, carrying out irradiation treatment under 60Co-gamma ray of which the radiation dosage is 1-10kGy; and finally, repeatedly performing ethanol soaking and water washing on the irradiated semen boitae so as to thoroughly wash off alkali lignin, the porous corn starch and the stabilizing agent on the surface of the semen boitae, and carrying out drying. Moreover, the ethanol soaking is also capable of further removing aspergillus flavus residues in the semen boitae. Results have proven that the method is capable of effectively eliminating aspergillus flavus pollution of the semen boitae, as well as reducing nutrient lose of the semen boitae to the maximum extent; and thus, levels of fatty acid, protein and so on of the grease-enriched semen boitae are almost unchanged before and after the irradiation; moreover, no chemical reagents are used so that the problem of chemical residue does not exist, and thus, safety of the food 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...
