Abstract

The invention discloses a chemical efficient degradation method for vomitoxin in grains, and relates to the technical field of food safety. The method comprises the following steps: soaking grains polluted by vomitoxin with subacid electrolyzed water, an ozone water solution and a subacid electrolyzed water-ozone water mixed solution in a mass ratio of (1: 2)-(1: 10) for 2-10 minutes; and removing the slightly acidic electrolyzed water-ozone water mixed solution, washing with flowing water, drying in a drying oven at 45 DEG C until the moisture content is about 13%, and finally detecting the vomitoxin of the dried grains. The invention provides a method for degrading vomitoxin of cereals such as wheat and the like by utilizing a subacid electrolyzed water-ozone fusion method, wherein the method has the advantages that the operation is simple and feasible, the treatment cost is low, a subacid electrolyzed water-ozone water mixed solution is safe and non-toxic, no pollution residue is caused, no harm is caused to a human body, and the like.

Description

technical field [0001] The invention belongs to the technical field of food safety, and in particular relates to a chemical-type high-efficiency degradation method for vomitoxin in grain. Background technique [0002] my country is a big grain producer, and wheat and corn are the staple food in our country. However, due to improper harvesting, storage or processing measures, wheat is easily contaminated with mycotoxins such as vomitoxin. Studies have shown that in the provinces where wheat is mainly grown, the wheat is polluted by DON to varying degrees. Deoxynivalenol, also known as deoxynivalenol, is a toxic metabolite produced by Fusarium graminearum, etc. It belongs to the trichothecene family of toxins and is a common mycotoxin. The pollution of grains and cereals by vomitoxin is very common and widely exists in grain crops such as wheat, barley, corn, etc. vomitoxin can cause vomiting, diarrhea, anorexia, nausea, nervous disorders and other toxic effects in humans an...
