High yield energy saving preparation method of Hericium erinaceus polysaccharide

Abstract

The invention discloses a high yield energy saving preparation method of a Hericium erinaceus polysaccharide. The preparation method comprises the following steps: 1, preparing Hericium erinaceus slices by slicing a raw material fruiting body of Hericium erinaceus; 2, mixing the Hericium erinaceus slices with water according to a solid-liquid ratio (g/ml) of 1:5-1:20 to obtain a Hericium erinaceus raw material, carrying out multistage dynamic countercurrent extraction with the help of supersonic waves, filtering to obtain a supernatant, and carrying out harmless processing on Hericium erinaceus residue; and 3, concentrating the supernatant by a double effect energy saving concentrator, carrying out alcohol precipitation, and drying to obtain the Hericium erinaceus polysaccharide. Comparedwith the prior art, the preparation method of the invention, which treats the fruiting body of Hericium erinaceus as the raw material, allows the fruiting body to be sliced and the Hericium erinaceuspolysaccharide to be extracted from the fruiting body with a multistage dynamic countercurrent extraction technology, has the advantages of substantially reduced energy consumption, short extraction period and flexible extraction; and the prepared Hericium erinaceus polysaccharide has the characteristics of high productivity, and strong gastric mucosa protection effect.

Description

technical field [0001] The invention relates to polysaccharide extraction technology, in particular to a preparation method of high-yield energy-saving Hericium erinaceus polysaccharide. Background technique [0002] Hericium erinaceum is the fruiting body (Hericium erinaceum) of the genus Hericium erinaceum in the family Dentalaceae. , into the liver and stomach two meridians, can benefit the five internal organs, help digestion, and replenish deficiency. Hericium erinaceus polysaccharide is one of its main functional components. Pharmacological tests show that Hericium erinaceus polysaccharide has various pharmacological effects, such as: anti-gastric and duodenal ulcer, anti-tumor, immune regulation, hypoglycemic, anti-fatigue, etc. Therefore, the preparation and extraction of Hericium erinaceus polysaccharide is particularly important. [0003] In the prior art, the polysaccharide of Hericium erinaceus is usually extracted by single-tank batch static extraction method ...

Problems solved by technology

Its extraction rate is closely related to the efficacy of the product, and also directly affects material consumption and cost

In addition, this existing single-tank batch static extraction method has two problems: ① Since the traditional extraction uses static extraction, there is a problem of equilibrium concentration limitation, it is difficult to achieve complete extraction, and the extraction yield Low, poor selectivity, serious waste of medicinal raw materials; ② The ratio of solvent to raw materials is large, generally the ratio of solid to liquid is about 1:10, and the space utilization rate of the extraction tank is extremely low, followed by a large volume of extraction liquid The concentration time is long and the energy consumption is huge

[0006] From the above research results, it can be seen that only using the static extraction method, the extraction rate of Hericium erinaceus polysaccharides does not exceed 8.2%, static hot water extraction, in ultrasonic, With the assistance of microwaves, etc., effective concentration gradients cannot be achieved, and the extraction rate is quite limited, and the extraction time is long, the solvent usage is large, and the energy consumption is high, which is not convenient for the popularization and promotion of industrialized large-scale production.

In addition, the new extraction technology and new equipment for industrial application are still immature, and many new dynamic countercurrent extraction processes require supporting new equipment, complex mechanical devices, and in the environment of complex extraction materials, failures are prone to occur, resulting in production interruption; and , only suitable for large-scale extraction. When the extraction volume is small, the long-term preparation work affects production efficiency and lacks flexibility.
