Problems solved by technology

However, due to the need to add enzymes in the extraction process, not only the production cost is high, but also the separation of the product is difficult.
Solvent extraction methods mostly use acidic or alkaline substances, which may have a certain impact on the biological activity and structure of polysaccharides
In addition, there are also research reports on the combined use of ultrasonic wall breaking and hot water extraction to extract polysaccharides from Ganoderma lucidum. Since the ultrasonic wave is used to crush Ganoderma lucidum first, and then the polysaccharides are extracted in a constant temperature water bath, although the crushing efficiency of Ganoderma lucidum can be improved to a certain extent, the processing capacity is relatively small. , the extraction time is long, and it is impossible to really go out of the laboratory for industrial production

Abstract

The invention discloses a method for preparing lucid ganoderma polysaccharides. The method comprises the following steps: using lucid ganoderma as a raw material; after overflow circulation ultrasonic shattering and extracting, separating a supernatant through high-speed centrifuging, removing proteins from the supernatant through circular current foam separation, and carrying out microwave vacuum drying to obtain lucid ganoderma polysaccharide powder. Due to the adoption of overflow circulation ultrasonic shattering and extracting, the shattering efficiency of the lucid ganoderma can be increased, the extracting rate of the lucid ganoderma active polysaccharides is increased, and automation operation can be conveniently carried out. The preparing method has the advantages of simplicity, low energy consumption, short time and capability of well preserving the natural activity of the lucid ganoderma polysaccharides and is suitable for industrial production. The obtained lucid ganoderma polysaccharides can be used for preparing different types of food, health food or drugs.

Description

technical field [0001] The invention belongs to the field of biochemical separation and purification, and in particular relates to a preparation method of ganoderma lucidum polysaccharide. Background technique [0002] Ganoderma lucidum is a treasure in the treasure house of traditional Chinese medicine in my country. It has the effects of preventing and curing diseases and prolonging life. It is known as "immortal grass". The "Shen Nong's Materia Medica" in the Eastern Han Dynasty and the "Compendium of Materia Medica" by Li Shizhen, a famous medical scientist in the Ming Dynasty, all have detailed records on the efficacy of Ganoderma lucidum. Today, Ganoderma lucidum has been officially recorded in the National Pharmacopoeia as a medicine. At the same time, it is a new resource food approved by the state. It has no toxic side effects and can be used for both medicine and food. [0003] Modern pharmacology and clinical practice have further confirmed that Ganoderma lucidum...
