Embodiment 1

[0034] Industrial extraction and separation of Ganoderma lucidum spore polysaccharides using the above device: Weigh 240kg of defatted spore powder and place it in 3.0T extraction tank 1, add 8 times the amount of spore powder to a total of 1.92T, heat to 100 degrees, extract with boiling water, and extract with constant temperature stirring for 2 hours Afterwards, the above-mentioned spore powder water extraction suspension was separated by decanter centrifuge 2 (drum speed 3800r / min, separation factor 2860) to obtain decanter solid phase powder residue and micro-suspended liquid phase, which were stored in decanter Because the speeds of the two centrifuges are different, a horizontal screw storage tank is needed for liquid storage. If the speed of the two can reach the same, they can be directly connected. The micro-suspended liquid phase in the horizontal screw storage tank 3 enters the butterfly centrifuge 5 (rotating drum speed 7600r / min, separation factor 10000), and separ...

Embodiment 2

[0036] Weigh 240kg of defatted spore powder and place it in 3.0T extraction tank 1. Add 10 times the amount of spore powder to 2.4T for boiling water extraction. After 2 hours of constant temperature stirring and extraction, the above-mentioned water extraction suspension of spore powder is passed through decanter in turn The series system of a type centrifuge (rotating drum speed 3800r / min, separation factor 2860), butterfly centrifuge (rotating drum speed 7600r / min, separation factor 10000) cyclically separates the liquid and solid phases. The final concentration is the Ganoderma lucidum spore powder polysaccharide extract (the yield of polysaccharide is 10.2%, and the content is 15.9%). The liquid phase was sampled for experimental analysis. The turbidity of the liquid phase was 107nut, which was relatively clear. The remaining unmentioned parts are the same as the above example.

Embodiment 3

[0038] Weigh 200kg of defatted spore powder and place it in the extraction device, add 12 times the amount of spore powder to 2.4T for boiling water extraction, stir and extract at constant temperature for 2 hours, then pass the above-mentioned spore powder water extraction suspension sequentially through a decanter centrifuge The series system of the machine (rotary drum speed 5000r / min, separation factor 3525), butterfly centrifuge (rotor drum speed 7060r / min, separation factor 11200) cyclically separates the liquid and solid phases. Concentrate to obtain Ganoderma lucidum spore powder polysaccharide extract (the yield of polysaccharide is 10.5%, and the content is 16%). The liquid phase was sampled for experimental analysis, and the turbidity of the liquid phase was 100nut, which was relatively clear. The rest of the undescribed parts are the same as in Example 1.

Abstract

An industrial extraction and separation method of ganoderma spore polysaccharide comprises the following steps: (1) placing spore powder into an extraction device, adding water with a weight 8 to 12 times of that of spore powder, heating until a slight boiling state is reached, and maintaining the temperature to carry out extraction for 2 hours; (2) delivering the obtained extract in a suspension state to a separation device to carry out solid-liquid separation, returning the solid phase to the extraction tank, extracting the solid phase for a second time, adding water with a weight 8 to 12 times of that of solid phase, heating until a slight boiling state is reached, maintaining the temperature to carry out extraction for 2 hours, separating solid and liquid, merging the two liquid phases, and condensing the merge liquid phase to obtain ganoderma spore polysaccharide extract. The separation device used in the step (2) is a circulation system, which is prepared by serially connecting a horizontal screw type centrifuge and a butterfly type centrifuge. The separation device can effectively remove spore residues from ganoderma spore water, and separates solids and liquid to obtain high-purity ganoderma spore polysaccharide in a high yield. The provided extraction and separation method has the advantages of short time and high polysaccharide yield, reduces the labor intensity, and can be applied to the industrial massive production of ganoderma spore polysaccharide.

Description

technical field [0001] The invention belongs to the technical field of deep processing of edible fungi, and in particular relates to an industrial extraction and separation method of ganoderma lucidum spore polysaccharide. Background technique [0002] Ganoderma lucidum (Ganodermalucidum) is a fungus of the genus Ganoderma lucidum in the Polyporaceae family. It is rich in nutrients and has a long history of consumption in China. Ganoderma lucidum spores are extremely tiny oval germ cells ejected from the gills of Ganoderma lucidum in the mature stage of growth. They are oval in shape, with an average short diameter of 8 μm and an average long diameter of 11 μm. Modern scientific research shows that Ganoderma lucidum spores have stronger physiological activities than Ganoderma lucidum fruiting bodies, and the main role is Ganoderma lucidum spore polysaccharide, which has various biological activities, such as inhibiting tumors, improving the body's immunity, and improving the...
