[0002] Wheat bran is the main by-product of wheat processing, containing more than 40% starch, 10-15% protein, and 8-9% crude fiber. The annual output of wheat bran in my country is about 20 million tons, which is a large Although some companies use wheat bran as raw materials to prepare and extract pentosan, oxalate oxidase, multifunctional dietary fiber, feruloyl oligosaccharides, antifreeze protein and other products, they have achieved certain economic and social benefits , but still failed to effectively solve the pollution problem and the comprehensive utilization of resources

Abstract

A method which is used for extracting maltose flour, zitan flour and cellulose by taking wheat bran as raw material belongs to the technical field of the comprehensive development of farm and sideline products and functional food additive. The technical points of the method are that ordinary wheat bran is stewed and pasted by adding water; high-temperature-resistant amylase and hemicellulase are added for enzymolysis; enzymolysis liquid is filtered to be processed for the enzymolysis, so as to obtain maltose liquid; compound proteinase is added into filter residues for the enzymolysis, the enzymolysis liquid is filtered again, filtrate is zitan liquid, and the filter residues is cleaned by water to obtain the crude product of cellulose with high purity. The maltose liquid and the zitan liquid are processed by separation, purification, concentration and spray-drying to obtain the maltose flour and the zitan flour. The maltose flour, the zitan flour and the cellulose are widely applied to the food service industry. The method of the invention extracts and uses three main component in the wheat bran synchronously for the first time, which really realize the effective increment and utilization of the wheat bran, and what is more important is that the technique of the invention does not discharge any pollutant during the actual production process.
