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 . 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.

The invention discloses blank-inside-and-outside-cooperated aging-resistant extruded wheat gluten and a preparation method therefor. The blank-inside-and-outside-cooperated aging-resistant extruded wheat gluten is prepared from the raw materials: low-gluten refined wheat flour, barley bran, glutelin powder, isomaltitol, table salt, chili powder, glycerol monostearate, edible oil, sesame oil, an enzymolysis product of konjac glucomannan, chitosan and water. According to the blank-inside-and-outside-cooperated aging-resistant extruded wheat gluten and the preparation method therefor, both the barley bran and the isomaltitol can fix food moisture inside the product to exert the effect of inhibiting product aging; the outside enzymolysis product of the konjac glucomannan and the chitosan can be attached to the surface of the product to form a layer of film, prevent moisture overflowing and retain moisture in the food, and the product aging can be effectively retarded, so that the blank-inside-and-outside-cooperated aging-resistant extruded wheat gluten and the preparation method therefor have a great application value in food industry.

The invention discloses a preparation method of a pH-responsive carrier, a drug delivery system and a preparation method of the drug delivery system. The preparation method of the pH-responsive carrier comprises the following steps: preparing a hydrazine hydrate solution, a rice bran polysaccharide solution, a polylactic acid solution, an N,N-dicyclohexylcarbodiimide solution and a 4-dimethylaminopyridine solution; adding the hydrazine hydrate solution into the rice bran polysaccharide solution, and performing reaction to generate a rice bran polysaccharide-hydrazine hydrate intermediate; dissolving the rice bran polysaccharide-hydrazine hydrate intermediate in a first solvent to obtain a rice bran polysaccharide-hydrazine hydrate solution; mixing the rice bran polysaccharide-hydrazine hydrate solution, the polylactic acid solution, the N,N-dicyclohexylcarbodiimide solution and the 4-dimethylaminopyridine solution, and performing reaction at 35-45 DEG C to obtain a reaction solution; and dialyzing the reaction solution with running water, collecting retentate, and performing drying treatment to obtain the pH-responsive carrier. The invention aims to develop the application of ricebran polysaccharide in a drug carrying system.
