Method for eliminating and reducing vomitoxin in grains by utilizing plasma activated water to moisten wheat

Abstract

The method comprises the following steps: preparing plasma activated water by using a plasma generator, and wetting grains polluted by vomitoxin by using the plasma activated water to obtain grains with vomitoxin eliminated and reduced; the method is simple and feasible to operate and low in treatment cost, the plasma activated water is safe, non-toxic, free of pollution residues and free of any harm to a human body, the plasma activated water is adopted to replace water for a traditional wheat wetting process, vomitoxin pollution in grains is effectively eliminated and reduced under the condition that an existing processing flow is not changed, and the method is suitable for industrial production. The elimination and reduction rate of vomitoxin in the wheat grains reaches 58% or above, meanwhile, the number of microorganisms in the wheat is remarkably reduced, and the treatment has no remarkable influence on main quality indexes and main quality parameters such as the appearance, the moisture content and the protein content of the wheat.

Description

technical field [0001] The invention relates to a method for reducing vomitoxin in grains by utilizing plasma activated water combined with a traditional wheat tempering process. Background technique [0002] Deoxynivalenol, also known as deoxynivalenol, is a type B trichothecene toxin produced by Fusarium fungus. It is one of the most common mycotoxins in grains and grain products. And one of the main pollutants detected in feed raw materials. Due to agricultural planting patterns and climatic conditions, wheat head blight and fusarium toxin pollution are common in China, and vomitoxin is the mycotoxin with the highest detection rate in my country's wheat. [0003] Deoxynivalenol can cause loss of appetite and vomiting, affect the intestinal barrier function, and has liver and kidney toxicity, immunotoxicity, reproductive genotoxicity and neurotoxicity, and poses a serious threat to human and animal health. [0004] DON has strong thermal and chemical stability, and it is...

AI Technical Summary

Problems solved by technology

The methods currently developed for the reduction of vomitoxin mainly include chemical modification, high temperature and high pressure treatment, ultraviolet or irradiation treatment, microbial degradation or enzymatic hydrolysis, etc., but these methods are more or less incompatible with food safety management regulations, equipment Expensive, great impact on food quality, possible introduction of new hazards, etc.
