Problems solved by technology
But the method that adopts at present all needs to add organic solvent and chemical preparation and adjust solution pH value in preparation process
The raw material low-temperature soybean meal is extracted with organic solvents, which not only increases the technical difficulty of production, but also produces poor production safety, and also produces a large amount of waste water

Embodiment 1
[0021] Embodiment 1, standard soybean protein production method.
[0022] 1. Degreasing soybeans and making soybean meal powder.
[0023] Soybeans from the soybean storage warehouse are measured and cleaned to remove light impurities, dust, stones, ironware, etc., and are sorted by a color sorter. Enter the skin, germ, and kernel separator, the skin and germ are collected separately and then output to the workshop, and the kernel is softened and rolled and heat-treated for 60-70 and then input into the press. The organic soybean oil obtained after being processed by a press machine is filtered, then filled into cans, labeled, boxed, and sold on the market; the obtained organic cake is used as a raw material of the present invention and crushed to 100 meshes.
[0024] 2. Soybean meal powder soaked in water.
[0025] Add low-temperature soybean meal powder b in the first dissolution and leaching tank 1 with stirring and heating devices shown in Figure 2, add 7-9 times the weig...

Abstract
The invention relates to a production method of soybean organic concentrated protein, which comprises crushed soybean pulp obtained after degreasing is performed through a squeezing method. The soybean pulp is immersed in water, and dairy salt and soda powder are added simultaneously during the immersion; the solution is segregated from the mixture of powder and water; the solution is put into a concentration gradient regulator or a double-effect evaporator to perform concentration; the concentrated solution is sterilized through high temperature; isotrope is performed, and the solution is dried, to obtain light yellow albumen powder grain with protein level of 60 to 70 percent. The invention has the positive effects that the raw material is organic soybean pulp squeezed through a machine, acid, alkali and alcohol are not used during the production process, to ensure that the product is green and organic, the natural taste is maintained, the invention contains all the protein of 2S, 7S, 11S and 15S and oligosaccharide, the isoflavone content in the product is five times higher than the prior art, and the lecithine content is enhanced by nearly 50 percent. The natural nutrition ingredient of the soybean is maintained to the maximum degree. The production water consumption is small, the water resource is saved, no waste water is drained, and the environment is not polluted. The production technology is simple, and the production cost is low.
Description
technical field [0001] The invention belongs to the field of food technology, in particular to a method for producing soybean protein. Background technique [0002] At present, the domestic production of soybean protein (isolated protein and concentrated protein) adopts the production process of DuPont technology in the United States or Japan's Fuji Company in the 1980s, that is, the low-temperature soybean meal after soybean oil soaked in solvent is used as raw material, and acid-base Extraction of protein by method or alcohol method (use solvent to adjust PH value). Such as: "A modification method of soybean protein concentrate (patent application number is 200410033836. Publication number is CN1689430A)"; "Technology for preparing soybean protein concentrate by continuous gradient extraction (patent application number is 200410098851, publication number is CN1631197A)" "The method for producing soybean protein (patent application number is 01802934.5 publication number i...
