Supercritical CO2 variable-temperature variable-pressure extraction method of lucid ganoderma spore oil

Abstract

The invention relates to a supercritical CO2 variable-temperature variable-pressure extraction method of lucid ganoderma spore oil. The method comprises the steps that: 1, lucid ganoderma spores are subjected to wall breaking, such that lucid ganoderma spore powder is obtained; 2, the wall-broken lucid ganoderma spore powder is prepared into particles with a dry-pressing method, such that particles with a size of 20-60 meshes are obtained; 3, the spore powder particles are placed into a supercritical CO2 extraction kettle with a three-stage separation structure; an ethanol water solution with a mass percentage of 20-95% is adopted as carrying agent, wherein 20-300ml of the 20-95% ethanol water solution is placed with each kilogram of material in the extraction kettle; and supercritical extraction is carried out, wherein an extraction pressure is 20-50MPa. The extraction process is a multi-stage extraction process, wherein extraction is carried out for 1-4h under a temperature of 30-40 DEG C, and extraction is carried out for 1-4h under a temperature of 40-60 DEG C. With the method, various effective components in lucid ganoderma spores can be more effectively extracted, such that the possibility for the lucid ganoderma spore active components to be broken is effectively reduced. The quality of the extraction product is improved, and the requirement of people is satisfied.

Description

technical field [0001] The present invention relates to the deep processing technology of Ganoderma lucidum spore powder, especially refers to the use of supercritical CO 2 A method for extracting Ganoderma lucidum spore oil by variable temperature and variable pressure technology. Background technique [0002] Ganoderma lucidum has been called "fairy grass" since ancient times. It has a long history of 5,000 years in China. It has always been regarded as a "panacea" by ancient emperors and a symbol of "good luck". ". The Ming Dynasty "Compendium of Materia Medica" records that Ganoderma lucidum "has a bitter taste, non-toxic, nourishes the middle and nourishes Qi, increases wisdom, has a good color, long-term food makes light of body and does not grow old, and prolongs life and immortality." Now, Ganoderma lucidum has been recorded in Chinese Pharmacopoeia, and it is an important raw material of Chinese medicinal materials and health food approved by the state. Ganoderma...

Problems solved by technology

Currently, most of the supercritical CO 2 The method of extracting spore oil is to put the broken spore powder into the extraction kettle, and pass through supercritical CO 2 Carry out extraction, introduce in a separation tank after depressurization, spore oil and some other components are separated and collected together, such as the method provided in Chinese patent ZL200610035574.8, ZL200610086075.1 and ZL02144759.4, because the spore powder Contains a variety of chemical components. Apart from water, there are other components precipitated with spore oil, such as esters, carotene and triterpenes. It is necessary to further remove these impurities by other methods to obtain spore oil essential oil , the process is increased, and impurities are difficult to completely remove and affect the purity of the oil

Using supercritical CO 2 There are many methods for extracting Ganoderma lucidum spore oil, but they are not perfect enough. It is necessary to further explore the best process conditions suitable for the production of Ganoderma lucidum spore powder
