Abstract
The invention discloses a kind of supercritical extraction method of oil of ginger, this method is that oil of ginger is extracted from ginger using supercritical carbon dioxide fluid.Sorting, cleaning, drying, crushing are carried out to ginger before extraction, extraction temperature is 25~65 DEG C, and pressure is 15~28MPa；Carbon dioxide is 1.0~1.3t/h by the flow of extraction kettle, and extraction time is 2~4h.The present invention is by the use of the CO 2 fluid under above-critical state as extractant, which recycles in same system, and solvent consumption is small, and price is cheap, therefore extracts at low cost.CO 2 fluid is green non-pollution solvent, the oil of ginger of extraction is good with quality, purity is high, color and luster is good, free from extraneous odour, no solvent residue, the features such as non-environmental-pollution, and extraction cycle is short, extracts the residue after oil of ginger also containing active ingredients such as starch, dietary fibers, can realize the comprehensive utilization of ginger.Present invention process is simple, and low energy consumption.
Description
Technical field
The invention belongs to technical field of natural product extraction, relate in particular to a kind of means of supercritical extraction side of oil of ginger
Method.
Background technology
Oil of ginger is the yellowish transparency liquid to yellow, and main component has zingiberone, zingiberol, zingiberene, ar-curcumene, Acacia
Xi, limonenes, cineole, β-phellandrene, borneol, linalool, methyl heptenone, aldehyde C-9, capraldehyde, Bronyl acetate, geraniol
And ginger element for having pungent etc., available for blending food essence, can also be used on a small quantity in some cosmetics, perfumed soap essence.
At present, oil of ginger, but these methods are mostly prepared using steam distillation, squeezing method, organic solvent extractionprocess
Not only recovery rate it is low, it is of high cost, have pollution, also easily damage effective ingredient therein.
The content of the invention
It is an object of the present invention to provide a kind of supercritical extraction methods of oil of ginger, improve oil of ginger recovery rate and oil
Quality, reduce environmental pollution, reduce extraction cost.
Technical scheme：
The present invention proposes a kind of supercritical extraction method of oil of ginger, and this method is using supercritical carbon dioxide fluid
Oil of ginger is extracted from ginger；Comprise the following steps：Sorting → cleaning → drying → crushing → extraction → separation → homogeneous → filling
Dress → preservation.Specifically：Ginger is dried before extraction, is crushed, will be put into through the dried ginger powder of appropriateness during extraction
In the material barrel of extraction kettle, carbon dioxide is injected into extraction kettle, keeps the temperature and pressure in extraction kettle in carbon dioxide
The supercriticality of gas is contacted with natural material, and the ginger oil component in ginger powder is made to be dissolved among supercritical fluid, from
Collect the fluid containing oil of ginger in the outlet of separating still.
Wherein, sorting and cleaning step are to choose fresh ginger as raw material, remove the impurity such as surface silt, then with clear
Water is cleaned, and is placed at shady and cool ventilation.Drying is will to be put into baking oven by the ginger of sorting and cleaning, will at a temperature of 50~60 DEG C
Ginger is dried to the dry ginger that water content is 10-15%.Crushing is that dried ginger is put into pulverizer to be ground into grain size big
In the ginger powder of 60 mesh.By sorting and cleaning two procedures, the purity of raw material can be greatly improved, improves recovery rate and oil
Quality；By drying process, the requirement to the temperature and pressure of supercritical carbon dioxide can be reduced so that in relatively low temperature and
Under pressure can either high efficiency complete extraction, and the service life of device can be extended, and the material after crushing disclosure satisfy that us
Requirement to material particular diameter increases the contact area of material and solvent, can greatly improve extraction yield.
Extraction step is that suitable ginger powder is put into the material barrel of extraction kettle, and carbon dioxide is injected and is extracted
Kettle keeps carbon dioxide in extraction kettle to be contacted in supercriticality with natural material, makes the ginger oil component in ginger powder
It is dissolved among supercritical fluid, the fluid containing oil of ginger is collected from the outlet of separating still.
Wherein, supercritical temperature is 25~65 DEG C, and pressure is 15~28MPa；The stream that carbon dioxide passes through extraction kettle
It measures as 1.0~1.3t/h, extraction time is 2~4h.
Separating step is that the recovery rate of the oil of ginger under optimum process condition is 7%.
Homogeneous, filling and preservation step is that the onion oil of same a collection of raw material is put into homogenizer, filling after homogeneous, is kept away
Light is stored refrigerated.
Compared with prior art, the invention has the characteristics that：By the use of the CO 2 fluid under supercriticality as extraction
Solvent is taken, which recycles in same system, and solvent consumption is small and price is cheap, therefore extracts at low cost；Titanium dioxide
Carbon flow body is green non-pollution solvent, and the oil of ginger of extraction has quality good, and purity is high, and color and luster is good, free from extraneous odour, solvent-free residual
It stays, the features such as non-environmental-pollution, and extraction cycle is short, extracts the residue after oil of ginger also containing starch, dietary fiber etc. effectively
Ingredient can realize the comprehensive utilization of ginger.Present invention process is simple, and low energy consumption.
