Ganoderma lucidum polysaccharide extracting method

Abstract

The invention discloses a ganoderma lucidum polysaccharide extracting method. The extracting method comprises the steps: firstly, smashing ganoderma lucidum sporocarp and sieving by a 80-mesh sieve; then putting into a steam explosion device to be exploded, adding into water to be soaked for 1.5h according to a solid to liquid ratio as 1 to (10 to 20) and then heating to 30 to 50 DEG C to performultrasonic treatment; adjusting a material liquid temperature, a pH value, protease and cellulase; after enzymolysis finishes, warming to denaturalize enzyme, centrifuging, decoloring resin, deproteinizing, filtering, vacuum concentrating and vacuum drying under a lower temperature to obtain high-activity and high-purity ganoderma lucidum polysaccharide solid powder. Therefore, a polysaccharide extracting rate and a polysaccharide production efficiency are improved, a space structure of polysaccharide is prevented from being damaged, biological activity of the polysaccharide is prevented frombeing reduced, and the ganoderma lucidum polysaccharide extracting method is more suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of polysaccharide extraction, and in particular relates to an extraction method of ganoderma lucidum polysaccharide. Background technique [0002] Ganoderma lucidum is a large basidiomycete with high nutritional and health value. Since ancient times, Ganoderma lucidum has been regarded as a symbol of auspiciousness, wealth, beauty and longevity. If the fungus is eaten directly, it generally cannot achieve the therapeutic effect. Usually, its active ingredients can only be extracted, separated and purified to improve the efficacy and exert certain pharmacological effects. A large number of research reports show that: Ganoderma lucidum polysaccharide is the main bioactive component of Ganoderma lucidum, and the various medicinal effects of Ganoderma lucidum are closely related to the activity and content of Ganoderma lucidum polysaccharide, and Ganoderma lucidum polysaccharide has become one of the most impor...

Problems solved by technology

Different from other edible fungi, the fruiting body of Ganoderma lucidum has a high degree of lignification and complex structure. Polysaccharides are generally combined with cellulose and lignin through physical or chemical bonds, making the fruiting body of Ganoderma lucidum have strong hardness, and the polysaccharides of Ganoderma lucidum exist in the fruiting body It is difficult to extract polysaccharides from the cell wall of

As can be seen from the current research results, the extraction rate of water-soluble Ganoderma lucidum polysaccharides is only about 3%, and most of the remaining polysaccharides are retained in the residue. If they are directly discarded, resources will be wasted and the environment will be damaged. create pollution

The traditional water, alkali and acid leaching extraction method takes a long time to extract Ganoderma lucidum polysaccharides, consumes a lot of energy, and the extraction temperature is high. Moreover, long-term high temperature may cause the degradation of Ganoderma lucidum polysaccharides, making it difficult to achieve the desired effect in the extraction of Ganoderma lucidum polysaccharides. Greatly limit the development and utilization of Ganoderma lucidum polysaccharide

In order to overcome the shortcomings of traditional water extraction methods, in recent years, new extraction technologies and methods such as ultrasound, microwave-assisted extraction, ultra-high pressure, and enzymatic methods have emerged, but the extraction effects of these methods are not ideal.
