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

Method for producing organic concentration protein of soybean

Technical field

The invention belongs to food technology field, be specifically related to a kind of production method of soybean protein.

Background technology

At present, domestic production soybean protein (protein isolate and protein concentrate) adopts all is Dupont technology or the production technology of the Japanese only company eighties in last century, be raw material promptly, extract albumen with acid-base method or pure method (using the solvent adjustment pH value) with the low temperature soy meal of soybean behind the solvent immersion oil.As: " a kind of method of modifying of FSPC (number of patent application is that 200410033836. publication numbers are CN1689430A) "; " technology of preparing concentrated soyabean protein by continuous gradient extraction (number of patent application is 200410098851, and publication number is CN1631197A) "; " produce the method (number of patent application is that 01802934.5 publication number is CN1392774) of soybean protein; "; " soy protein isolate and production method (number of patent application is that 200380108672.4 publication numbers are CN1738540) "; " a kind of method (number of patent application is that 200410029589.4 publication numbers are CN1561787) of extracting soybean protein ".But the method that adopts all needs to add organic solvent and chemicals and regulator solution pH value in preparation process at present.The raw material low temperature soy meal is again that organic solvent extracts, and has not only increased the technical difficulty of producing, and production security is also relatively poor, also produces a large amount of waste water simultaneously.Dissolvent residual is arranged in the product, is not green organic food.

Summary of the invention:

The purpose of this invention is to provide method for producing organic concentration protein of soybean, overcome soybean protein production process and products obtained therefrom above shortcomings in the prior art.

Technical scheme of the present invention may further comprise the steps:

1, resulting bean cake powder after the milling process degreasing is broken to granularity 80-120 order.

2, with the bean cake powder water logging of step 1 gained, water consumption is 7-9 a times of bean cake powder weight, initial water temperature 45-60 ℃, add the salt of bean cake powder weight 0.2-0.5% and the soda ash of bean cake powder weight 0.2-0.5% when adding water, above composition is heated, when temperature rises to 75-90 ℃ after mixing while stirring, be incubated 15-20 minute, press GMP as the need defoamer and carry out.

3, the mixture of completing steps 2 is gone into seperator, in mixture is flowed through the seperator process, isolates solution.

4, will concentrate from solution input concentration gradient adjuster or the double effect evaporator that step 3 obtains, solid content is increased to about 15% by 10%, get concentrate.

5, the concentrate input flash vessel that step 4 is obtained carries out high-temperature sterilization.

6, the concentrate of completing steps 5 input homogenizer carries out homogeneous, imports the spray drying tower spray-drying behind the homogeneous, obtains the faint yellow albumen powder of protein content 60-70%.

Below promptly get standard type product of the present invention.

If produce drink type soybean protein, the adjustment that the present invention did is:

The solution input agitator tank that step 4 is obtained, enzyme-added and stir by employed dregs of beans siccative weight 0.1-0.5%, and then sterilize, homogeneous, drying process.

For improving the yield of protein in the raw material, further improvement of the present invention is:

The isolated slag of step 2 is added slag weight 2-4 times, temperature 75-90 ℃ hot water again, add the edible soda ash of slag weight 0.1-0.5%, carry out the secondary water logging.The isolated liquid of secondary water logging is incorporated in the isolated solution of water logging for the first time.

Good effect of the present invention is

Because raw material of the present invention is that machine presses organic dregs of beans, and do not use soda acid, alcohol in the production process, it is green organic can making product, keep natural flavour mountaineous, contain whole 2S, 7S, 11S, 15S albumen and compound sugar, the isoflavone content in the product can improve 5 times, lecithin content than existing manufacturing technique and improve nearly 50%.Product at utmost keeps soybean natural nutrition, helps health.The industrial water amount is little, saves great lot of water resources, and non-wastewater discharge is free from environmental pollution.Production technology is simple, has reduced the investment of equipment such as environmental protection, has reduced production cost.
