Embodiment 1

[0035] When the DON content in the wheat is 487.68μg / kg, spray the ozone water with a concentration of 6.5mg / L according to the amount of 2.5% of the weight of the wheat. After the ozone water and the wheat are fully mixed for 5 minutes, use the peeling machine for the first peeling. Remove 3.0-3.5% of the bran (3.0-3.5% is the peeling rate, which refers to the percentage of the weight of the removed bran to the total weight of the wheat before peeling), and then evenly spray 0.8% of the weight of the wheat with a concentration of 6.5mg / L ozone water, moisten the wheat for 25 minutes, then peel it twice to remove the remaining 1.5-2.0% of the bran (1.5-2.0% is the peeling rate, which means the weight of the removed bran accounts for the total weight of the wheat before peeling ), and finally into the mill to obtain wheat flour, the content of DON in the wheat flour determined by HPLC method is 29.38μg / kg, no ozone residue. The wheat flour of the same batch of wheat is made by ...

Embodiment 2

[0037] When the DON content in the wheat is 933.21μg / kg, spray the ozone water with a concentration of 9.0mg / L according to the amount of 3.0% of the weight of the wheat. After the ozone water is fully mixed with the wheat for 5 minutes, use the peeling machine for the first peeling. Remove 3.0-3.5% of the bran, and then evenly spray 1.0% of the weight of the wheat with ozone water with a concentration of 6.5mg / L, moisten the wheat for 30 minutes, then peel it twice to remove the remaining 1.5-2.0% of the bran, and finally mill it The wheat flour was obtained by grinding. The content of DON in the wheat flour was determined by HPLC to be 83.93μg / kg, and there was no residual ozone. The wheat flour of the same batch of wheat produced by the traditional milling process (the traditional process is the direct grinding of the wheat after water infiltration), the DON content is as high as 398.27μg / kg. Compared with the quality of wheat flour obtained by traditional flour milling proc...

Abstract

The invention provides a method of lessening vomitoxin in wheat flour and belongs to the technical field of wheat flour detoxification. The method comprises the steps of 1) mixing wheat and ozone water for the first time, detoxifying the mixture, and carrying out first skinning to obtain wheat firstly skinned; and 2) mixing the firstly skinned wheat with ozone water for the second time, detoxifying the mixture, carrying out second skinning, and grinding the secondly skinned wheat to obtain flour, so that vomitoxin in the wheat is lessened. The concentration of the ozone water is 5-10 mg / L. Thedouble-channel skinning technique is used independently for the first skinning and the second skinning and includes iron roller skinning and emery roller skinning. The method provided herein has better removal effect for vomitoxin in wheat and causes no secondary pollution.

Description

Technical field [0001] The invention belongs to the technical field of wheat flour detoxification, and particularly relates to a method for reducing vomiting toxins in wheat flour. Background technique [0002] Vomiting toxin (DON), also called deoxynivalenol, is a compound of the trichothecenes family, mainly from the Fusarium genus, including Fusarium graminearum and Fusarium flavum. DON is widely present in wheat and its products, and has a high pollution rate worldwide. DON's pollution of grains and cereals is related to factors such as toxin-producing strains, temperature, humidity, ventilation, and sunshine. Once wheat is contaminated by the toxin-producing strains of vomitin, the toxin-producing strains will grow rapidly in a suitable growth environment to produce DON, and the DON in the wheat will be brought into the flour along with the production and processing of wheat flour. Experimental studies have confirmed that DON has cytotoxicity and immunotoxicity. After huma...
