The invention discloses natural cereal and coarse cereal composite nutritional flour and a preparation method thereof, and relates to the technical field of flour preparation, the natural cereal and coarse cereal composite nutritional flour comprises the following raw materials: wheat flour, modified oat flour, modified corn flour, auxiliary coarse cereal flour and silicon dioxide; according to the invention, the modified oat flour is added, and through triple synergistic modification, the solubility and bioavailability of beta-glucan in oat are greatly improved, the water binding capacity and thermal stability of the composite flour are also enhanced, starch retrogradation is effectively inhibited, and the shelf life of a finished product is prolonged; pure physical modification does not have chemical residues, so that the composite flour is suitable for special crowds with diabetes, celiac disease and the like, and the defect that common coarse cereal composite flour is insufficient in functionality is overcome; the modified corn flour is added, the problems that common corn flour is low in dietary fiber solubility and poor in dough stability can be solved, a compact network is formed through synergy of natural polysaccharides, the water holding capacity and processing fluidity of the composite flour are improved, and water loss and caking in the cooking or baking process are reduced.

The application discloses a method for removing off-flavor of thiozole. The method comprises the following steps: (1) mixing crude thiozole to be treated with an oily solvent and standing; if the mixture is stratified, transferring the oily solvent layer to a new container; if the mixture is not stratified, directly performing subsequent operations; (2) performing vacuum distillation on the product of step (1) to remove the solvent and obtaining a paste; (3) adding a lower alcohol to the paste and heating to dissolve; (4) performing vacuum distillation on the solution of step (3) to remove the solvent; and (5) performing vacuum distillation on the product of step (4) again to distill thiozole products. The method removes off-flavor by-products in the crude thiozole through extraction with an oily solvent, removes part of impurities through dissolution and distillation with a lower alcohol, distills thiozole at last, separates high-boiling-point residue impurities, removes off-flavor, retains the characteristic odor of thiozole, makes the prepared thiozole smell like beef and have nutty aroma, and has no off-flavor, and thus meets the industry standard.

The application discloses a kind of flame-retardant sound insulation noise reduction antibacterial non-woven felt and preparation method thereof, it is related to automotive interior product technical field, including non-woven felt body, the non-woven felt body also includes substrate layer and is arranged in the antibacterial layer of substrate layer, the substrate layer is made of flame-retardant polyester staple fiber, and antibacterial layer is made of inorganic antibacterial material, preparation method also includes the substrate layer that is formed with antibacterial layer is mixed 30% with 80% polyester staple fiber and yarn is made into non-woven felt body by needle punching and / or water jet, spunlaid non-woven process of sticking.This application uses regenerated polyester as raw material, realizes the regeneration and recycling of polyester material, is friendly to environment, and can substantially reduce the cost of industry chain, make hollow structure, can effectively heat insulation sound insulation noise reduction function;Load inorganic antibacterial powder such as nano zinc oxide, nano silver, nano titanium dioxide in hollow structure, can effectively inhibit the adhesion growth of bacteria, mould, effectively prolong the service life of product.
