Abstract

The invention discloses a method for treating aflatoxin B1 in stored corn by using chlorine dioxide, which belongs to the technical field of food engineering. The method comprises the steps that cornis flatly laid in a closed storage chamber, and the corn is in a flowing type; chlorine dioxide gas with a concentration of 60-100mg/L is introduced into the closed storage chamber, and fumigating iscarried out for 12-24 hours in the closed storage chamber; and finally, ventilation is conducted, and the corn storage conditions in the closed storage chamber are set as follows: under the standard atmospheric pressure, the humidity is 60-75%, and the temperature is 20 DEG C or below. According to the method, the chlorine dioxide gas is used as a degradation substance of the aflatoxin B1, the aflatoxin B1 in the stored corn is treated under the conditions of specific chlorine dioxide gas concentration, treatment time and the like, and the degradation rate of the aflatoxin B1 can reach 78%; and meanwhile, the processing method is suitable for large-scale corn storage.

Description

technical field [0001] The invention relates to a method for treating aflatoxin B in corn, in particular to a method for treating aflatoxin B in stored corn by using chlorine dioxide 1 The method belongs to the technical field of food engineering. Background technique [0002] Aflatoxins are widely polluted in oil crops, mainly infecting grain and oil crops such as peanuts, cottonseeds, corn, and nuts. The stress of high temperature and drought is the main reason for the infection of Aspergillus flavus before the closed harvest, and it is easy to erupt before or after the harvest; however, if it encounters rainy weather during the closed harvest, it is also prone to damp and mildew and produces aflatoxin; Improper storage conditions after harvest can also cause the infection of Aspergillus flavus and produce aflatoxin. Because aflatoxin can cause cancer, teratogenicity and mutagenesis, it is extremely harmful to humans and animals, which has attracted widespread attention ...
