Problems solved by technology

[0007] To sum up, the two patented technologies for drying and purifying Ganoderma lucidum spores with publication numbers CN102766593A and CN101703531A both have high water temperature for washing (use normal temperature water instead of low temperature), long washing and soaking time, and Insufficient aspects such as the temperature used for drying are too high, resulting in the purified product not meeting the quality requirements

Embodiment 1

[0037] Example 1 Low-temperature washing and high-speed centrifugal vacuum drying technology to purify Ganoderma lucidum spores

[0038] (1) Take 5 kg of newly harvested Ganoderma lucidum spore powder, pour it into a 400-mesh steel sieve twice, wash and filter in a low-temperature ice-water bath at 4°C, vibrate and sieve continuously, and discard the filter residue. This operation takes 10 minutes completed within.

[0039] (2) Put the frozen filtrate into the SS450 three-leg filter centrifuge for rapid dehydration, the centrifugal speed is 2000 r / min, and slowly adjust the supernatant discharge valve at the beginning to remove the supernatant and impurities smaller than the spore size, The supernatant just discharged is milky white gaseous water, and then turns into a transparent liquid; the centrifugation time is about 10 minutes, and when no gaseous water is discharged, it indicates that the dehydration process is completed; after shutting down the centrifuge, immediately t...

[0051] Example 3 Low-temperature washing and high-speed centrifugal vacuum drying technology to purify Ganoderma lucidum spores

[0052] (1) Take 5 kg of newly harvested Ganoderma lucidum spore powder, pour it into a 400-mesh steel sieve twice, wash and filter in a low-temperature ice-water bath at 6°C, vibrate and sieve continuously, and discard the filter residue. This operation takes 10 minutes completed within.

[0053] (2) Put the frozen filtrate into the SS450 three-leg filter centrifuge for rapid dehydration, the centrifugal speed is 1500 r / min, and slowly adjust the supernatant discharge valve at the beginning to remove the supernatant and impurities smaller than the spore size, The supernatant just discharged is milky white gaseous water, and then turns into a transparent liquid; the centrifugation time is about 15 minutes, and when no gaseous water is discharged, it indicates that the dehydration process is completed; after shutting down the centrifuge, immediately t...

Abstract

The present invention discloses a ganoderma lucidum spore purification method, which specifically comprises: placing harvested ganoderma lucidum spore powder into ice water with a temperature of 2-6 DEG C, washing, screening, and collecting the filtrate; centrifugating the filtrate, and carrying out high speed centrifugation dehydration to obtain massive ganoderma lucidum spore powder; and carrying out vacuum drying on the massive ganoderma lucidum spore powder to obtain the purified ganoderma lucidum spore powder. According to the present invention, low temperature washing, high speed centrifugation and vacuum drying are adopted so as to reduce physiological metabolism activity of ganoderma lucidum spores, shorten a ganoderma lucidum spore soaking time in water, effectively avoid fermentation rancidity of ganoderma lucidum spore powder during a processing process, and well maintain the original aromatic flavor of ganoderma lucidum spore powder; and compared with the conventional filtration and purification method, the method of the present invention has the following characteristics that: the required time is shortened by 5 times, product purity achieves 100%, and production efficiency and product quality of industrial production are effectively increased.

Description

technical field [0001] The invention relates to the technical field of Ganoderma lucidum purification technology, in particular to a method for purifying Ganoderma lucidum spores. Background technique [0002] The spores of Ganoderma lucidum are the essence of Ganoderma lucidum, which are the seeds ejected from the lower surface of the fruiting body of Ganoderma lucidum, commonly known as spores. The spores are collected in powder form, commonly known as Ganoderma lucidum spore powder. The shape of Ganoderma lucidum spores is oval, with a size of 8 microns x 5 microns. Because it is so tiny, its shape cannot be seen clearly with the naked eye. Only by using electron microscope scanning technology to magnify the spores by 10,000 to 100,000 times can their true colors be revealed. During the cultivation process of Ganoderma lucidum for several months, it is inevitable that some fragments of the culture medium and aged mycelium will fall off and be mixed in the spore powder.
