Problems solved by technology

[0003] The traditional method of extracting Ganoderma lucidum spore oil is generally to use organic solvents such as methanol or ethanol to extract. This extraction method has disadvantages such as cumbersome operation, many extraction times, low extraction efficiency, large energy consumption, and the active ingredients are easy to become rancid during the extraction process.

Embodiment 1

[0022] Select 8 kg of Ganoderma lucidum spore powder, carry out pretreatment steps such as screening, washing and filtering, so that the purity of the Ganoderma lucidum spore powder is at least 98%, dry it in an oven at 50° C. for 4 hours, and pulverize it to obtain a coarse powder. Mix the coarse powder and double-distilled water evenly in a weight ratio of 1:5, and perform ultrasonic wall breaking treatment by an ultrasonic cell disruptor (the power of the ultrasonic cell disruptor is 100-1000W, and the frequency is 20-80KHz), and the obtained mixed The solution was freeze-dried in a freeze dryer to obtain Ganoderma lucidum spore powder. Use vitamin C as a filler, mix ganoderma lucidum spore powder with vitamin C that accounts for 8% by weight of ganoderma lucidum spore powder, and granulate through a granulator (the pressure of the granulator is 3-6MPa) to obtain 10-40 mesh ganoderma lucidum Spore powder particles. Ganoderma lucidum spore powder particles are placed in a s...

Abstract

The invention provides a method for supercritical extraction of ganoderma lucidum spore oil, which comprises the following steps: 1) pretreating, drying and smashing to obtain coarse powder; 2) mixing the coarse powder and double distilled water uniformly, performing ultrasonic wall breaking treatment, freezing and drying the mixed solution to obtain ganoderma lucidum spore powder; 3) mixing the ganoderma lucidum spore powder with vitamin C and granulating to obtain ganoderma lucidum spore powder particles; 4) subjecting the ganoderma lucidum spore powder particles to CO2 supercritical extraction; 5) separating ganoderma lucidum spore oil components. The method has the advantages of simple process, low cost, high yield of ganoderma lucidum spore oil and high product activity, and can be widely used in the technical field of extraction of ganoderma lucidum spore oil.

Description

technical field [0001] The invention relates to a method for extracting ganoderma spore oil, in particular to a method for supercritically extracting ganoderma spore oil. Background technique [0002] Ganoderma lucidum is a fungus of Polyporaceae, known as "immortal grass", and has a significant effect on improving human immune function. Ganoderma lucidum spores are the seeds released by the growth and maturity of Ganoderma lucidum. They are the germ cells of Ganoderma lucidum. They have all the genetically active substances of Ganoderma lucidum. Sterols, polysaccharides, alkaloids and other components are the aggregates of active components of Ganoderma lucidum spores, which have various physiological activities. Among them, the triterpenoids of Ganoderma lucidum are the main active ingredients of Ganoderma lucidum. The world’s Ganoderma lucidum research experts in China, France, Korea, Japan and other countries have conducted experiments by extracting Ganoderma lucidum th...
