Abstract

The invention relates to a method for synchronously extracting soybean oil and soybean milk powder by an aqueous enzymatic method, which belongs to the technical field of plant grease processing. The method comprises the following steps: 1) dehulling soybeans and performing ultramicro grinding on the soybeans, extruding the soybeans and puffing the ground material to obtain a puffed product; 2) adding water into an enzymatic hydrolysis reaction vessel, heating steam and adding the puffed product to obtain mixed liquor, adjusting pH value of the mixed liquor, adding alkali protease for performing enzymatic hydrolysis, using a horizontal centrifuge after enzymatic hydrolysis is carried out for performing centrifugation to obtain emulsified oil, a hydrolysate and residues; and 3) using a disk centrifuge for performing centrifugation on the emulsified oil to obtain the soybean oil and a water phase, adding the water phase into the hydrolysate for concentration, and drying the material to obtain the soybean milk powder. The method has the advantages of simple process, short reaction time, less enzyme usage amount and low cost, and the prepared soybean oil has no solvent residues and has high quality. The soybean milk powder can be prepared when the soybean oil is prepared, the soybean milk powder can keep partial fat, and has advantages of rich bean fragrance, abundant nutrition, and good brewing property, and is suitable for continuous industrial production.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil processing, and mainly relates to a method for synchronously extracting soybean oil and soybean milk powder by an aqueous enzymatic method. Background technique [0002] The traditional methods of producing vegetable oil are mainly pressing and leaching. The pressing method has a simple process and less supporting equipment, which can maintain the special flavor of the product, but the oil extraction rate is low, the energy consumption is high, and the cost is high. Moreover, the protein denaturation of the cake after pressing is serious, and the protein utilization rate is low, resulting in a serious waste of vegetable protein. . The leaching method has high production efficiency and low residual oil rate, but this method requires a lot of equipment, large investment, large loss of oil flavor and residual organic solvents, and requires refining treatment, and also pollutes the environment....
