Embodiment 1

[0025] (1) Put the freshly harvested spore powder into a container, pour into pure hot water at 50°C to soak the seeds for 13 minutes, the amount of hot water is 4 times the amount of seeds, and stir continuously during treatment to make them evenly heated. Then soak the seeds for another 2 hours at a normal temperature of 20° C. to obtain wet spore powder, whose water content is determined to be 60%.

[0026] (2) Put the wet spore powder into a centrifuge with a rotating speed of 7,000 rpm and a relative centrifugal force of 60,000×g. After centrifuging for 8 minutes, take it out and dry it for 20 minutes to obtain wet spore powder with scattered properties.

[0027] (3) Put the wet spore powder with scattered properties into a -70°C ultra-low temperature refrigerator, and take it out after 30 minutes to obtain a low-temperature-60°C frozen spore powder.

[0028] (4) Put the frozen spore powder into -180°C liquid nitrogen to make its temperature drop sharply, and take it out ...

Embodiment 2

[0033] (1) Put the freshly harvested spore powder into a container, pour 52.5°C pure hot water to soak the seeds for 14 minutes, the amount of hot water is 4.5 times the amount of seeds, and stir continuously during treatment to make them evenly heated. Then soak the seeds for another 2.5 hours at a normal temperature of 22.5° C. to obtain wet spore powder, whose water content is determined to be 65%.

[0034] (2) Put the wet spore powder into a centrifuge with a rotating speed of 7,500 rpm and a relative centrifugal force of 65,000×g. After centrifuging for 9 minutes, take it out and dry it for 25 minutes to obtain wet spore powder with scattered properties.

[0035] (3) Put the wet spore powder with scattered properties into a -70°C ultra-low temperature refrigerator, and take it out after 35 minutes to obtain a low-temperature -65°C frozen spore powder.

[0036] (4) Put the frozen spore powder into -190°C liquid nitrogen to make its temperature drop sharply, and take it out...

Embodiment 3

[0041] (1) Put the freshly harvested spore powder into a container, pour into pure hot water at 55°C to soak the seeds for 15 minutes, the amount of hot water is 5 times the amount of seeds, and stir continuously during treatment to make them evenly heated. Then soak the seeds for another 3 hours at a normal temperature of 25° C. to obtain wet spore powder, whose water content is determined to be 70%.

[0042](2) Put the wet spore powder into a centrifuge with a rotating speed of 8,000 rpm and a relative centrifugal force of 70,000×g. After centrifuging for 10 minutes, take it out and dry it in the air for 30 minutes to obtain wet spore powder with scattered physical properties.

[0043] (3) Put the wet spore powder with scattered properties into a -70°C ultra-low temperature refrigerator, and take it out after 40 minutes to obtain a low-temperature -70°C frozen spore powder.

[0044] (4) Put the frozen spore powder into -200°C liquid nitrogen to make its temperature drop shar...

Abstract

The invention discloses a preparation method of reishi shell-broken spore powder at temperature difference ultrahigh pressure by a wet process. The preparation method comprises the following steps: soaking fresh reishi spore powder so as to absorb water, putting into a centrifugal machine, centrifuging, airing, then putting into an ultralow-temperature refrigerator and liquid nitrogen sequentially, refrigerating so as to obtain the ultralow-temperature wet spore powder with cracked pore shells, then carrying out microwave unfreezing treatment so as to obtain dried shell-broken spore powder, and finally acquiring sterile spore powder with high shell breaking rate under ultrahigh pressure. The method provided by the invention can be used for solving the technical difficulties of low shell breaking rate, food pollution and difficulty in releasing polysaccharide in the processing course; the reishi shell-broken spore powder prepared by the invention has the characteristics of high spore powder shell breaking rate, no pollution source and easiness in absorption of functional inclusions.

Description

technical field [0001] The invention belongs to the technical field of food engineering, and relates to a preparation method of ganoderma lucidum spore powder, in particular to a method for preparing ganoderma lucidum spore powder with ultra-high pressure of wet temperature difference. Background technique [0002] As a traditional Chinese medicinal material with thousands of years of medicinal history, Ganoderma lucidum has high medicinal value. Ganoderma lucidum has a significant effect on enhancing human immunity. Ganoderma lucidum spores are the seeds released in the later stage of development of Ganoderma lucidum, which are called basidiospores in biology. The chemical components in Ganoderma lucidum spores, such as carotene, sterols, triterpenoids, and alkaloids, have many functions on the human body. The two-layer wall wrapped by Ganoderma lucidum spores is very tough, and it is difficult to break it. If the wall is not broken, its chemical components and biologicall...
