Embodiment 1

[0019] A high-efficiency extraction method for water-soluble soybean polysaccharides, specifically comprising the following steps:

[0020] (1) Homogenization: crush the plump soybeans and pass through a 80-mesh sieve to obtain soybean powder. Add distilled water 5 times the weight of soybean powder to the soybean powder, heat to 67°C, and homogenize at 36MPa for 40 seconds to save soaking and Beating time, saving water, preventing nutrient loss, cooling to 45~50°C to obtain soybean raw material slurry;

[0021] (2) Fermentation: Add lactic acid bacteria to the soybean raw material slurry so that the concentration is 3% (v / v), mix evenly, and ferment at a constant temperature of 40°C for 12 hours to decompose the protein in the soybean, reduce impurities, slowly adjust the pH, and promote soybean fermentation. The polysaccharide is precipitated, centrifuged at 8000 rpm for 10 minutes, and the precipitate is removed to obtain soybean fermentation liquid;

[0022] (3) Concentra...

Abstract

The invention discloses an efficient water-soluble soybean polysaccharide extraction method. The method includes: (1) homogenization; (2) fermentation; (3) concentration; (4) drying; (5) packaging. The efficient water-soluble soybean polysaccharide extraction method is simple, efficient and available for large-scale production, operation efficiency is improved by 14.3%, extraction rate reaches 37.83%, purity reaches 76.32%, and production cost is saved by 12.6%. Water is directly added for homogenization after soybeans are ground, so that soaking time is greatly saved, and production cost is saved as well. By fermentation with various lactobacilli and joint actions of various fermented products, water-soluble soybean polysaccharide precipitation is promoted, and extraction rate is increased fundamentally. Soybean fermentation liquor is only heated and boiled for concentration in a short time, so that energy saving is realized, and ethyl alcohol consumption is reduced. By low-temperature precipitation after addition of the ethyl alcohol, flocculent precipitate generation of soybean polysaccharides is promoted, and precipitation time is evidently shortened.

Description

technical field [0001] The invention mainly relates to the field of extraction of soybean polysaccharides, in particular to a high-efficiency extraction method of water-soluble soybean polysaccharides. Background technique [0002] Water-soluble soybean polysaccharides are high-molecular carbohydrates extracted from soybeans. They have various biological activities and have good therapeutic effects on diabetes, cardiovascular and cerebrovascular diseases, and gallstones. Water-soluble soybean polysaccharides can also be used as food additives, which can produce stable foam, prevent protein precipitation, and have excellent emulsification, water retention, and oil retention properties. They can be used in baking, beverages, and functional health foods, etc., and have broad market prospects. [0003] At present, the extraction methods of water-soluble soybean polysaccharides include acid method, alkali method and enzymatic method, etc., but they all have the disadvantages of c...
