Abstract

The invention discloses a preparation method for ganoderma spores oil, which belongs to the technical field of bio-engineering. The preparation method for the ganoderma spores oil comprises the steps as follows: log ganoderma spores powder with wall-broken by water-washing is selected as raw material and wetted by solvent to prepare the grains; at the temperature of 30-55 DEG C, the grains are dried to a state that the water content is less than 3%; the grains are put in a supercritical CO2 extraction kettle and extracted by supercritical CO2, with the extraction pressure of 28-35MPa, the temperature of 42-48 DEG C, the flow rate of CO2 of 20-30L / H and the extracting time of 2 hours; subsequently, the two-stage separation is carried out, with the separation pressure of 8-10MPa and the separation temperature of 53-57 DEG C for the first-stage separation and the separation pressure of 3-5Mpa and the separation temperature of 30-40 DEG C for the second-stage separation; the mixture which is separated by two stages is put statically under normal temperature for 10-20 days; subsequently, supernatant is taken for filtering so as to obtain buff oily matter; the buff oily matter is further separated and purified so as to obtain the product. The preparation method for the ganoderma spores oil provided by the invention has the advantages of short extracting time, high yield, high content of effective composition, suitable pressure, mild operation condition and easy industrialized production.

Description

technical field [0001] The invention relates to a preparation method of ganoderma lucidum spore oil, in particular to a method for extracting ganoderma lucidum spore oil with supercritical carbon dioxide. Background technique [0002] Ganoderma Lucidum (Curtis: Fr) P.Karst, commonly known as Ganoderma Lucidum, Seicao, belongs to Basidiomycetes and Polyporaceae. It is a traditional traditional Chinese medicine that strengthens the body, nourishes and strengthens the body. It has been used for more than 5,000 years in my country. Edible history. There are suitable species distributions in different ecological environments, which have constituted a rich group of Ganoderma lucidum, especially the red Ganoderma lucidum has the most prominent effect. [0003] Ganoderma lucidum spores are the reproductive cells that are continuously ejected from the cap of Ganoderma lucidum during the mature period. These microcells are the seeds for the reproduction of the next generation of Ganod...
