Abstract
The invention discloses a kind of Bletilla glucomannan extracting methods, comprising the following steps: (1) feedstock processing；(2) gelatinization；(3) it digests；(4) it is dried after alcohol precipitation.Bletilla glucomannan extracting method extraction process of the invention is relatively easy, strong operability, is able to achieve large-scale production, and product is odorless, tasteless powder, and purity is high, extraction efficiency is high, and small to bletilla polysaccharide destructiveness.
Description
Technical field
The present invention relates to a kind of Bletilla glucomannan extracting methods.
Background technique
The bletilla striata is orchid family bletilla striata platymiscium, the also known as small bletilla striata, lotus and grass, snow such as end, over the past thousands of years always as tradition
Chinese medicine uses, and major function is sore hemostasis, tonifying lung, detumescence and promoting granulation etc..Contain a large amount of water soluble polysaccharide in bletilla striata bulb,
Its chemical component is mainly glucomannan, and minimum its of molecular weight is the main function ingredient of Bletilla glucomannan.Bletilla striata polyoses glue
A kind of excellent natural thickener, be the higher medical material of safety, performance brilliance pharmaceutic adjuvant and have suitable development
The biomedical material of prospect.In addition, bletilla striata polyoses glue applies also in daily chemical products, chemical thickening agent is substituted, and have
Reduce the functions such as irritation, protection skin, anti-aging.
Currently, conventional Bletilla glucomannan extracting method, efficiency is not high enough, therefore is often used the nondominant hands such as high temperature, ultrasound, acid adding
Section increases extraction efficiency, but these means can cause certain destruction to beneficiating ingredients such as polysaccharide, causes gained finished product white
Splendid achnatherum glue quality decline.Therefore, it is high to find a kind of extraction efficiency, and to the destructive small Bletilla glucomannan extracting method right and wrong of bletilla polysaccharide
It is often important.
Summary of the invention
The object of the invention is that providing a kind of extraction efficiency height to solve the above-mentioned problems, and broken to bletilla polysaccharide
The small Bletilla glucomannan extracting method of bad property.,
To achieve the goals above, the present invention is achieved by the following technical solutions: a kind of Bletilla glucomannan extracting method, including with
Lower step:
(1) feedstock processing: decocting 5 minutes or so after the fresh bletilla striata is removed root, takes out slice, is placed under 80 °C and dries, and is made thick
Powder；
(2) gelatinization: taking coarse powder to be placed in pot, after gauge water cold soaking is added, is put into the pot equipped with thermostatted water that be stirred continuously 1.5 small
When after colorless and transparent glue, glue heating is concentrated into the volume of 2:1；
(3) it digests: glue standing is cooled to 40-50 DEG C, after protease is added, tank is maintained by liquefaction, using two sub-high pressures
Then injection, hydrolysis time 40-60min are added activated carbon adsorption and deodorize, the processing time is 20-30min, rear to be centrifugated
Take supernatant liquor；
(4) it is dried after alcohol precipitation: being slowly added to the static alcohol precipitation 24-48h of dehydrated alcohol of twice of mass under stirring in supernatant liquor,
Sediment is filtered to obtain, the Bletilla glucomannan obtained by drying under 90 °C.
Particularly, whether there is or not the white hearts for the determining fresh bletilla striata before step (1) slice, have white core white splendid achnatherum to be no more than 1%.
Further, the mass ratio of step (2) the cold soaking water, thermostatted water and coarse powder are as follows: 1-2:1-2:3-6；
Further, 105-107 DEG C of step (3) the mesohigh injection temperation one time, 125-127 DEG C secondary, pressure is
0.2-0.4mPa。
In summary the invention has the following advantages: Bletilla glucomannan extracting method extraction process of the invention is relatively simple
Single, strong operability is able to achieve large-scale production, and product is odorless, tasteless powder, and purity is high, extraction efficiency is high, and to the bletilla striata
Polysaccharide destructiveness is small.
Specific embodiment
A kind of specific embodiment: Bletilla glucomannan extracting method, comprising the following steps:
(1) feedstock processing: decocting 5 minutes or so after the fresh bletilla striata is removed root, takes out slice, determines that the fresh bletilla striata has before slice
Without the white heart, there is white core white splendid achnatherum to be no more than 1%(without the best of the white heart)；It is placed under 80 °C and dries, coarse powder is made；
(2) gelatinization: taking coarse powder to be placed in pot, after 2 times of quality water cooling leachings are added, is put into the pot of the thermostatted water equipped with 3 times of quality
Colorless and transparent glue is obtained after being stirred continuously 1.5 hours, and glue heating is concentrated into the volume of 2:1；
(3) it digests: glue standing is cooled to 40-50 DEG C, after protease is added, tank is maintained by liquefaction, using two sub-high pressures
Injection, 105-107 DEG C of high-pressure injection temperature one time, 125-127 DEG C secondary, pressure 0.2-0.4mPa, hydrolysis time 40-
Then 60min is added activated carbon adsorption and deodorizes, the processing time is 20-30min, and rear centrifuge separation takes supernatant liquor；
(4) it is dried after alcohol precipitation: being slowly added to the static alcohol precipitation 24-48h of dehydrated alcohol of twice of mass under stirring in supernatant liquor,
Sediment is filtered to obtain, the Bletilla glucomannan obtained by drying under 90 °C.
Embodiment provided above is better embodiment of the invention, only is used to facilitate to illustrate the present invention, not to this hair
It is bright to make any form of restriction, any those of ordinary skill in the art, if not departing from the proposed skill of the present invention
In the range of art feature, using the equivalent embodiment for locally changing or modifying made by disclosed technology contents, and
Without departing from technical feature content of the invention, in the range of still falling within the technology of the present invention feature.
