Method for reducing vomitoxin content of wheat, wheat flour and flour product

Abstract

The invention discloses a method for reducing vomitoxin content of wheat, wheat flour and a flour product, and relates to the technical field of grain processing. The method for reducing the vomitoxincontent of the wheat comprises the following steps: performing specific gravity grading treatment on the wheat to be treated to obtain light wheat and heavy wheat; putting the light wheat into a sodium chloride solution, and performing stirring and standing, so that components of which the density is greater than that of the sodium chloride solution in the light wheat settle to form bottom-layerwheat; and collecting the bottom-layer wheat, performing drying treatment, and then mixing the dried bottom-layer wheat with the heavy wheat to obtain qualified wheat, wherein the density of the sodium chloride solution ranges from 1.14-1.22 g/cm<3>. According to the invention, the toxin content in the wheat is efficiently reduced, and good wheat in the light wheat can be recycled, so that the loss of the good wheat is avoided; meanwhile, the method provided by the invention does not need high-temperature heating, and only introduces sodium chloride which is a non-toxic exogenous component, thereby ensuring the quality and safety of wheat.

Description

technical field [0001] The invention relates to the technical field of grain processing, in particular to a method for reducing the content of wheat vomitoxin, wheat flour and flour products. Background technique [0002] Fusarium head blight (FHB) is a serious fungal disease of cereals. FHB will not only cause agricultural and economic losses such as grain yield reduction, quality decline, and grain germination, but also the secondary metabolite deoxynivalenol (DON), namely vomitoxin, has harmful effects on the liver, kidney, and immune system of mammals. And the nervous system has also had severe damage. [0003] Appropriate detoxification of grain and feed is an important method to control and reduce the harm of mycotoxins. At present, the common detoxification methods in production mainly include heat treatment detoxification method, chemical detoxification method, adsorption detoxification method and so on. The high-temperature heating process in the heat treatment m...

AI Technical Summary

Problems solved by technology

The high-temperature heating process in the heat treatment method will destroy the original nutritional value of the food, and new toxic substances may be produced after thermal decomposition; when the adsorbent is used for detoxification, the mycotoxin adsorbent will also adsorb DON in the raw material. Micronutrient elements cause the loss of nutrients in the feed; the implementation conditions of the chemical detoxification method are relatively harsh, and some potential toxic substances will remain, and other uncertain factors will be introduced, causing secondary pollution to the grain

In summary, the traditional detoxification methods of DON are limited in practical application.
