Abstract

The invention provides a method for reducing vomitoxin of wheat bran through extrusion. The method mainly comprises the following steps: 1, putting the wheat bran in water, adding alkali to adjust the wheat bran to be alkaline; 2, drying the alkaline wheat bran, then compounding the wheat bran and starch according to a certain proportion, and mixing evenly; 3, extruding and detoxifying a mixture of the wheat bran and the starch in an extruder; 4, neutralizing the alkali. The wheat bran powder prepared according to the method is high in content of dietary fibers and low in vomitoxin, can serve as an additive to be mixed with various other food base materials to prepare various foods with rich dietary fibers, and has a quite extensive scope of application.

Description

Technical field [0001] The invention relates to the field of wheat bran and processing, in particular to a method for reducing wheat bran vomiting toxin by extrusion. Background technique [0002] Vomitoxin, also known as deoxynivalenol (DON), chemically named 3α, 7α, 15-trihydroxyfusarium-9-en-8-one, belonging to trichothecenes The compound, so named because it can cause vomiting in pigs, has a certain harmful effect on the human body. Pollution of vomiting toxin is widely found in countries around the world, including China, Japan, the United States, the former Soviet Union, and South Africa. Vomiting toxin mainly pollutes cereal crops such as wheat, barley, oats, and corn, and also pollutes food products such as bread, biscuits, and wheaten snacks. In addition, vomiting toxin residues were found in animal milk and eggs. The pollution of vomitoxins to grains is related to the toxin-producing strains, temperature, humidity, ventilation, sunshine and other factors. Wheat head...
