[0065] Example 2 Industrial production example of alcohol precipitation method for separation and purification of soybean isoflavones, soybean saponins, soybean oligosaccharides and functional soybean protein concentrate

[0066] (1) Put low-temperature desolvated soybean meal from the feed port, and use countercurrent continuous extraction equipment and ultrasonic device to extract, adjust the feed rate to 300Kg / hour, the solvent flow rate to 800Kg / hour, and the extraction temperature to 60°C. It is transported to the filter unit through the infusion centrifugal pump.

[0067] (2) The extract is pumped into the storage tank through coarse filtration and fine filtration to obtain the extract A.

[0068] (3) cut off 10t extract A with the Membralox aperture that U.S. Pall Company produces is the microfiltration device of 5.0 μ m (2-alumina) and the Membralox aperture is 20nm (zirconia) ultrafiltration device, carries out microfiltration and ultrafiltration process, The pressur...

Abstract

The present invention discloses the method of extracting active functional soybean factors, including soybean isoflavone, soybean spanin, soybean oligosaccharide and functional concentrated soybean protein, from defatted soybean residue. Specially, the process of the present invention includes extracting defatted soybean residue with edible alcohol solution to obtain extracted liquid, concentration and alcohol precipitation of the extracted liquid, and conventional refining process to obtain high purity soybean isoflavone, soybean spanin, soybean oligosaccharide and functional concentrated soybean protein. The present invention has product safety, simple technological process, raised product quality and low production cost, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for preparing soybean isoflavones, soybean saponins, soybean oligosaccharides and soybean protein concentrate. More specifically, the present invention relates to a method for simultaneously extracting multiple active functional factors from defatted soybean products, including soybean isoflavones, soybean saponins, soybean oligosaccharides and soybean protein concentrates. The method has simple process, all grades of products and extraction solvents can be comprehensively utilized, and is a practical technology suitable for large-scale industrial production of soybean isoflavones, soybean saponins, soybean oligosaccharides and soybean protein concentrate. Background technique [0002] According to data, soy isoflavones have multiple physiological functions, can combine with estrogen receptors, play a two-way regulation effect on estrogen, prevent and treat osteoporosis, and prevent and treat menopausal syndrome, which...
