Supercritical CO2 extraction method of ganderoma lucium oil

Abstract

The present invention discloses a method for extracting ganoderma spore oil by using supercritical CO2 extraction process. Said method includes the following steps: (1), using wall-broken ganoderma spore powder as raw material, mixing the wall-broken ganoderma spore powder with a certain quantity of granular filling material according to mixing ratio of 10:1-1:10; (2), placing the mixed raw material into an extraction still, introducing CO2 and extracting for 2-5 h at 10-35 MPa and 35-55 deg.C; (3), controlling first-level separation still pressure to make it be 8-10 MPa, making separation at 30-50 deg.C, after the extraction is completed, discharging light-yellow ganoderma spore oil from outlet of separation still; and (4), controlling second-level separation still pressure to make its be 4-6 MPa, making separation at 30-50 deg.C, after the extraction is completed, discharging small quantity of water.

Description

technical field [0001] The present invention relates to the extraction technology of Ganoderma lucidum spore oil, especially refers to a kind of supercritical CO 2 Method for extracting Ganoderma lucidum spore oil. Background technique [0002] The Ganoderma lucidum spores released when the fruiting bodies of Ganoderma lucidum mature contain the essence of Ganoderma lucidum. The content of active ingredients is 75 times higher than that of Ganoderma lucidum, and the amount that can generally be collected is only 1% of the weight of the Ganoderma lucidum body. Because it has a hard chitin shell, the active ingredients in it are difficult to be absorbed and utilized by the human body. Scientific research has proved that it takes 24 hours for human enzymes to decompose Ganoderma lucidum spore powder. Normally, unbroken spore powder can only stay in the gastrointestinal tract for 4 to 6 hours after oral administration. In addition, the spores are very small and egg-shaped, and ...

AI Technical Summary

Problems solved by technology

Chinese patent CN1445346A discloses that unbroken Ganoderma lucidum spore powder is expanded with supercritical CO 2 Extraction method, but the higher temperature in the process of puffing will make some active ingredients of Ganoderma lucidum spore oil inactive, and at the same time accelerate the oxidation of oil

Chinese patent CN1114446C discloses a method for extracting effective active substances of Ganoderma lucidum spores, specifically involving the extraction of Ganoderma lucidum spore powder with supercritical CO 2 Extraction, but the mentioned conditions are very broad, and it is difficult to obtain high yields in actual production

Chinese patent CN1094766C also discloses a supercritical extraction processing method of ganoderma lucidum spore oil, which involves granulating ganoderma spore powder and then extracting it, but the granulation process is relatively complicated

Chinese patent CN1586295A also discloses Ganoderma lucidum spore oil and its preparation method and application. It also involves extraction of Ganoderma lucidum spore powder after granulation, granulation with ethanol solution, and hot air drying. The process is complicated, and ethanol is flammable and unsafe.
