Embodiment 1

[0029] 1. Take the filter residue of extracting soybean isoflavones from alcohol defatted soybean meal, and remove residual ethanol by plate and frame pressure filtration;

[0030] 2. Take the bean dregs obtained in 1kg1, add 4kg of water to it, and grind it with a coarse grinder to form bean paste;

[0031] 3. The bean paste is further ground with a colloid mill (the aperture of the colloid mill is 0.2mm);

[0032] 4. Put the bean paste into the sterilization and deodorization unit, and process it at a temperature of 125°C for 10 seconds;

[0033] 5. Hydrolyze soybean paste with neutral protease, hydrolyze for 12 hours under the conditions of pH 7.0, temperature 40°C, and 5.0 g neutral protease, and repeat the hydrolysis once under the same conditions;

[0034] 6. Inactivate the hydrolyzed bean paste at 90°C for 20 minutes, then filter to remove soluble matter;

[0035] 7. Use pectin lyase (pectinase) and endoglucanase (cellulase) to hydrolyze the bean paste obtained in 5 a...

Embodiment 2

[0038] Embodiment 1 gained product gets 80g (in dry matter), then gets whey protein 20g, 800mg vitamin A, 1mg vitamin E, 1200mg calcium lactate (in calcium ion), 10mg ferrous lactate (in iron ion), 5 mg of zinc gluconate (calculated as zinc ions) was homogenized under a pressure of 20 MP for 10 minutes, concentrated, and spray-dried (inlet temperature 160° C., outlet temperature 80° C.) to obtain soybean fiber granules.

Embodiment 3

[0040] The same method as in Example 1 is used to process the defatted bean dregs to prepare the product, the only difference is that the conditions for hydrolysis with neutral protease are: pH 7.0, temperature is 60°C, and neutral protease is 1.0 g; pectinase and cellulose The conditions for enzymatic hydrolysis are: PH is 8, temperature is 30°C, pectinase is 2.5g, cellulase is 1.8g, the pectinase used is specifically pectin esterase, and the cellulase is cellobiohydrolase .

Abstract

A method for processing the defatted soybean dregs as the by-product generated by extracting soybean isoflavone from defatted soybean cake features that said fatted soybean dregs are hydrolyzed by use of neutral proteinase, pectinase and cellulase to obtain soybean fiber product with high content of soluble fiber.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a soybean product processing method and the obtained product. Background technique [0002] Usually defatted soybean meal is used to extract soybean isoflavones, but the by-product defatted soybean dregs of this process is often discarded, which causes a large degree of waste and increases the production cost. [0003] So far, the extraction and production methods of soybean dietary fiber are mainly as follows: the raw materials, such as fresh bean dregs and bean skin, are first hydrolyzed with papain and lipase to remove protein and fat, and then the protein and fat are removed under the condition of pH 9. Stir to prepare and filter out the soluble components, hydrolyze the insolubles with 0.04% cellulase for 1 to 24 hours to obtain soybean fiber products, and then carry out post-processing, such as drying, crushing, etc., where drying can be done by flash evaporation, drying, Mi...
