Example Embodiment

[0025] Example 1

[0026] S1. Take clean ginseng and cut it into slices with a thickness of 5 mm, and place it in a steam explosion tank. First pass nitrogen until the pressure in the steam explosion tank is 1 MPa, and explode for 15 minutes; then quickly pass steam to the pressure in the steam explosion tank It is 1.6MPa, steam explosion treatment for 1.6min, drying, and ginseng powder is obtained;

[0027] S2. Put the ginseng powder obtained in step S1 into an enzymatic hydrolysis tank, and add a biological composite enzyme preparation containing mixed protease, pectinase, glucoamylase, lignin degrading enzyme, and laccase at a ratio of 85.0 ml / ton, 35 ℃, enzymolysis under the action of high-voltage pulsed electric field for 4 hours, electric field strength 30kv / cm, 8 pulses;

[0028] S3. Heat the enzymatically hydrolyzed solution at 100°C for 6min to passivate it, add a natural source turpentine derivative with a concentration of 72.5% to extract 2.5 times at a temperature of 77....

Abstract

The invention discloses a method for extracting a blood sugar-reducing panaxan by an enzyme method and the application of the obtained panaxan. The method comprises the following steps of after slicing clean gen-seng into slices with the thickness of 5mm, performing steam explosion treatment on the slices, and drying the slices to obtain gen-seng powder; placing the obtained gen-seng powder in an enzymatic vessel, adding biologic composite enzyme preparations containing mixed protease, pectinase, glucose amylase, lignin-degrading enzyme and laccase into the vessel, and performing enzymolysis for 3 to 5 hours under the action of a high-pressure pulse field; heating the solution obtained after enzymolysis for 5 to 7 minutes at the temperature of 100 DEG C to passivate the solution, adding an organic solvent into the solution to leach for 2 to 3 times, performing centrifugal separation, and after mixing the supernatants, performing spray drying to obtain powder, wherein the drying temperature is not more than 65 DEG C, and the water content is controlled to be less than 7 percent. Due to the fact that in an enzymolysis reaction process, a steam explosion treatment technology and the high-pressure pulse field are introduced, the activity of the enzyme preparation is improved, the enzymolysis reaction speed is increased, and dissolution of saponin substances in the gen-seng is quickly and effectively promoted.

Description

technical field [0001] The invention relates to the technical field of polysaccharide extraction and application, in particular to a method for enzymatically extracting hypoglycemic ginseng polysaccharide and the application of the obtained polysaccharide. Background technique [0002] Ginseng (Panaxginseng C.A.Mey) is the dried root of Araliaceae plant ginseng, commonly known as ginseng, ghost cover, goblin, baby ginseng, etc. It is a precious medicinal material in my country and has a medicinal history of thousands of years. Ginseng is mild in nature, sweet in taste, slightly bitter and lukewarm. It has the effects of invigorating vital energy, recovering pulse and strengthening the spleen, nourishing the spleen and lung, promoting body fluid and quenching thirst, calming the nerves and improving intelligence. In recent years, scholars at home and abroad have conducted pharmacological studies, clinical observations and epidemiological examinations on the active ingredients...
