Description

A kind of preparation method of ginseng/American Ginseng nanometer decomposing and fermenting extract
Technical field
The present invention relates to ginseng/American Ginseng extracting method, more particularly to a kind of ginseng/American Ginseng nanometer decomposing and fermenting extraction The preparation method of thing.
Background technology
Ginseng is the perennial root grass for belonging to Araliaceae Panax in Plant Taxonomy, on earth known kind About 11 kinds, representative kind has Korean ginseng, Changbai Mountain ginseng, American Ginseng.Korean ginseng is mainly grown in Far East Asia (Korea Spro State, Northeast China be northern, Russian some areas), drug effect is outstanding.Changbai Mountain ginseng is mainly grown in the band of northeast Changbai Mountain one, American Ginseng is mainly in the U.S., Canada's area growth and cultivation.
With delivering for ginseng main component and pharmacological action correlative study, attracted tremendous attention as natural health food, Its demand also gradually increases, and is further speeded up because of the raising of economy and living standards of the people, is being widely used as popular type Natural health food.Sweet, the slight bitter of ginseng, tepor, have reinforce vital energy, veins takes off admittedly, reinforce the spleen to benefit the lung, blood-nourishing of promoting the production of body fluid, peace The effect of refreshing intelligence development, while its complex chemical composition, bioactivity is extensive, and pharmacological action is unique.As modern times separation is analyzed The development of technology and medical sci-tech, the research of the chemical composition of ginseng make some progress, and it mainly contains ginsenoside Class, polysaccharide, volatile oil, aliphatic acid and some trace elements.Modern pharmacology research proves that ginseng has antitumor, tune Nervous system is saved, improves cardiovascular system, anti-oxidant, hypoglycemic and raising immunologic function etc..
The content of the invention
It is an object of the invention to provide a kind of preparation method of ginseng/American Ginseng nanometer decomposing and fermenting extract, this method The active principle contained in ginseng/American Ginseng is more effectively discharged using the collective effect of probiotics and saccharomycete, with Traditional extraction process is compared, and active constituent content significantly improves in extract.
The purpose of the present invention is achieved through the following technical solutions:A kind of ginseng/American Ginseng nanometer decomposing and fermenting carries The preparation method of thing is taken, is comprised the following steps:
(1) Feedstock treating:Ginseng/American ginseng medicine is carried out disinfection, washing and drying treatment, obtain net ginseng/the West Ginseng;
(2) crush:Net ginseng/ginseng powder is broken into nanometer powder, obtains ginseng/American Ginseng nanometer powder;
(3) it is inoculated with:Add nitrogen source in ginseng/American Ginseng nanometer powder, probiotics is inoculated with after carbon source and water stir and Saccharomycete, obtain fermentation materials;
(4) ferment:Fermentation materials ferment more than 1 day at 45-55 DEG C;
(5) filter:After the completion of fermentation, the filtered processing of fermenting mixture of gained, ginseng/American Ginseng enzyme liquid is obtained, That is ginseng/American ginseng extract.
In the step (1), ginseng/American ginseng medicine is carried out disinfection processing using Ozone Water, and the drying is then adopted With air-dried or less than 50 DEG C low temperature dryings.
In the step (2), net ginseng/ginseng powder is broken into by nanometer powder using substep grinding mode, is used as this hair Bright one embodiment, is carried out in three steps crushing in the present invention, and net ginseng/ginseng powder is broken into the big of 2-5mm by the first step Net ginseng/american ginseng granules are crushed to the little particle that particle diameter is 0.3mm-15 μm by particle, second step, and the 3rd step continues net people Ginseng/American Ginseng little particle is crushed to nano particle, produces ginseng/American Ginseng nanometer powder.
In the step (3), the inoculum density of probiotics is 1%~10%, and saccharomycete inoculum density is 1%~10%. The probiotics includes but is not limited to lactobacillus and Bifidobacterium.The lactobacillus includes but is not limited to lactobacillus acidophilus, cheese Lactobacillus.The Bifidobacterium includes but is not limited to bifidobacterium longum, bifidobacterium breve, avette Bifidobacterium, thermophilic bifid bar Bacterium.Described saccharomycete is Ascomycota Blastocystis.
In the step (3), per in 1kg ginsengs/American Ginseng nanometer powder, nitrogen source addition is 1-5 parts, carbon source and water 95-99 parts.The nitrogen source includes but is not limited to soybean protein, and the carbon source includes but is not limited to granulated sugar.The granulated sugar and water system It is added to again in ginseng/American Ginseng ultra-micro powder after into the sugar solubility that concentration is 25-50%, and by the water of the fermentation materials Sub-control system is within 10%.
In the step (4), fermentation materials fermentation time is preferably 10-40 days.
Further, present invention additionally comprises milling step, i.e. step (6):Ginseng/American Ginseng enzyme liquid and excipient mixing Uniformly, ginseng/American Ginseng ferment powder is obtained after freeze-drying.
The present invention has the advantages that compared with prior art:
The present invention uses microbial fermentation technology, using probiotics and the collective effect of saccharomycete, in ginseng/American Ginseng The active principle contained more effectively discharges, as shown in Figure 2-5, compared with traditional extractive technique, ginseng/American Ginseng Active ingredient, ginsenoside Rb1, ginsenoside Rb2, total saposins and polyoses content are higher, and can more play ginseng/American Ginseng has The effect of strengthen immunity.
