Problems solved by technology

The patent "mycotoxin detoxification equipment for grain and oil agricultural products" with the publication number CN 203015779U is a detoxification equipment that uses ozone generator to generate ozone to degrade mycotoxins in peanuts, corn, rice and other grains, but no ozone detoxification fungus is found in this patent The specific test parameters of toxins, and the effect of ozone on the reduction of mycotoxins has not been seen; Li Mengmeng's master's thesis "Research on Deoxynivalenol Degradation Technology in Scab Wheat" studied the use of ozone generators to generate ozone to treat scab wheat However, the utilization rate of ozone in this research is low, it takes a long time, the degradation efficiency of vomitoxin is low, and the ozone tail gas is directly discharged outdoors without treatment, which is not good for the environment.

Embodiment 1

[0038] A method for rapidly reducing vomitoxin in wheat, the specific steps are as follows:

[0039] (1) removing impurities from wheat grains (with a water content of 12.0-14.0%), and pouring 200 g of the removed wheat grains into a 1L reaction tower (9) to form a material layer (12);

[0040] (2) Connect the reaction tower (9) into the ozone on-line elimination small wheat vomitoxin device, open the condensed water (5), open the main valve of the oxygen tank (2), and slowly adjust the pressure reducing valve of the oxygen tank (3) to ensure that the oxygen tank The outlet pressure is at 1.4Mpa, and the pressure of oxygen in the ozone generator is at 0.1Mpa at this moment, adjust the oxygen flow rate of the ozone generator (4) to ensure that oxygen passes through the ozone generator at a flow rate of 2L / min;

[0041] (3) Turn on the ozone generator (4), the ozone concentration inlet detector (7) and the outlet detector (8), and turn on the current control button of the ozone ...

[0045] A method for rapidly reducing vomitoxin in wheat, the specific steps are as follows:

[0046] (1) removing impurities from wheat grains (with a water content of 12.0-14.0%), and pouring 200 g of the removed wheat grains into a 1L reaction tower (9) to form a material layer (12);

[0047] (2) Connect the reaction tower (9) into the ozone on-line elimination small wheat vomitoxin device, open the condensed water (5), open the main valve of the oxygen tank (2), and slowly adjust the pressure reducing valve of the oxygen tank (3) to ensure that the oxygen tank The outlet pressure is at 1.4Mpa, and the pressure of oxygen in the ozone generator is at 0.1Mpa at this moment, adjust the oxygen flow rate of the ozone generator (4) to ensure that oxygen passes through the ozone generator at a flow rate of 10L / min;

[0048](3) Turn on the ozone generator (4), the ozone concentration inlet detector (7) and the outlet detector (8), and turn on the current control button of the ozone ...

Embodiment 3

[0052] A method for rapidly reducing vomitoxin in wheat, the specific steps are as follows:

[0053] (1) passing wheat flour (with a water content of 15.0 to 17.0%) through a 30-mesh sieve to remove impurities therein, and pouring 200 g of the removed wheat flour into the reaction tower (9) to form a material layer (12);

[0054] (2) Connect the reaction tower (9) into the ozone on-line elimination small wheat vomitoxin device, open the condensed water (5), open the main valve of the oxygen tank (2), and slowly adjust the pressure reducing valve of the oxygen tank (3) to ensure that the oxygen tank The outlet pressure is at 1.5Mpa, and the pressure of oxygen in the ozone generator is at 0.1Mpa at this moment, adjust the oxygen flow rate of the ozone generator (4) to ensure that oxygen passes through the ozone generator at a flow rate of 6L / min;

[0055] (3) Turn on the ozone generator (4), the ozone concentration inlet detector (7) and the outlet detector (8), and turn on the ...

Abstract

The invention discloses a method for quickly reducing vomitoxin in wheat. The method comprises the following steps: (1) pouring wheat raw materials with removal of impurities into a reaction tower; (2) connecting an ozone generator with the reaction tower so that ozone is capable of going into the reaction tower to react with the vomitoxin in the wheat raw materials, wherein the ozone concentration is 0-100mg / L. The method for quickly reducing the vomitoxin in wheat is used for reducing the vomitoxin in wheat or wheat flour, and is simple in process, specific in parameter and remarkably improved in reduction rate; as a result, the vomitoxin in wheat can be reduced quickly, safely and effectively, and the reduction rate can be above 80%.

Description

technical field [0001] The invention relates to the field of food safety, in particular to a method for rapidly reducing vomitoxin in wheat. Background technique [0002] my country is a big country of grain production. Wheat and corn are the staple food of our country. The annual planting area and output of wheat in our country are about 25% and 22% of the total grain. 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. [0003] Deoxynivalenol, also known as deoxynivalenol, is a toxic metabolite produced by Fusarium graminearum, etc. It belongs to the trichothecene family compound 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, ...
