Study on the Manufacture and Feature of the Crushed Product of Acidic Treated Soybean Residue

Abstract

Because soybean residue contains a large amount of carbohydrate, protein, fiber, fat and so on, people's interest on soybean residue is increasing day by day, in order to use soybean residue in various food industry research is carried out widely. In this, through the method of extracting water-soluble soybean polysaccharides in the soybean residue that it is rich and the method of destroying the structure of SR, the conditions of improving the physical properties of SR is determined and the research for testing its properties is done. Firstly, the method and experiment design for extract water-soluble soybean polysaccharides is determined scientifically. Secondly, in order to improve the physical properties of SR, the optimal method of solution and treatment to destroying the structure of SR is selected scientifically. Through various experiment is carried out, that the best solution to destroying the structure of SR is the diluted solution of HCl is determined scientifically. The optimal treatment condition to improve the physical properties of SR is 0.04M of hydrochloric acid concentration, 70? of temperature and 3 hours of time. The SR treated in this condition showed good powdering and the crushed products were very high in dispersion, emulsification stability and oil absorbed force.
