Description
Technical field
The present invention relates to food, medicine, chemical field, particularly a kind of method of from plant, extracting volatile matter.
Background technology
Volatile matter is a kind of effective constituent contained in a lot of plants, and these compositions much have tangible activity, is widely used in food, medicine, chemical industry fragrance industry, from former plant, extracts volatile matter, the following several method of main at present employing:
(1) supercritical extraction: supercutical fluid is meant that certain gas or gaseous mixture are when working pressure and temperature all are higher than stagnation point; Make its density near liquid; And its spread coefficient and viscosity be all near gas, the fluid of its character between gas and liquid.The supercritical fluid extraction technology is exactly to utilize supercutical fluid to be solvent, from solid or liquid, extracts some active principle, and carries out isolating a kind of technology, the CO that uses at present
2Abstraction technique adopts high-tension apparatus, and very high to equipment requirements, the facility investment appropriate litigation fees is big, and most of medium-sized and small enterprises are difficult to accept;
(2) steam the slide method: ultimate principle is dalton's voltage divider principle; Utilize the boiling point of mixed solution to be lower than the boiling point of each component; Volatile matter can steam being lower than under the temperature of its boiling point boiling, thus the decomposition that causes because of high temperature when avoiding volatile matter to distill separately, though this method investment is less relatively; But extract yield is low, under the normal circumstances less than 50%;
(3) absorption process: utilize the method for greasy fat-soluble absorption volatile oil, be usually used in the extraction of valuable spices, can keep the distinctive fragrance of volatile oil, but, have a certain amount of residual owing to quote the external application solvent;
(4) milling process: the method for mechanical expression is used for the extraction of volatile oil in the higher fresh feed of oleaginousness more, can keep the distinctive fragrance of volatile oil, but extracts not exclusively;
(5) solvent method: utilize the fat-soluble of volatile oil, adopt lower boiling lipotropy organic solvent ether, Petroleum ether extraction, because ether etc. is inflammable, explosive etc., so only as laboratory method.
At present, more pharmaceutical manufacturer and middle pot foods, chemical enterprise adopt and steam the extraction of slide method, and large-scale food, chemical enterprise adopt supercritical CO more
2Extraction process extracts, and owing to extracting process, can't satisfy the problem of practical demand, and therefore, the improvement of the method for extraction volatile matter is imperative with innovation from plant.
Summary of the invention
To above-mentioned situation, be to solve the defective of prior art, the present invention's purpose just provides a kind of method of from plant, extracting volatile matter, can solve effectively that the yield that exists in the existing method is low, cost is high, guaranteed not the problem of quality.
The technical scheme that the present invention solves is may further comprise the steps:
(1) plant powder is evenly packed into after wetting with ethanol (90%～95%) in microscler jar, the upper end constantly adds high concentration ethanol (90%～95%), and the lower end is connected with basin, and diacolation speed is 1～3ml/ (minkg), and the collection percolate is in jar;
(2) more than vacuum tightness-0.08mpa, under the condition of temperature below 50 ℃, reclaim the ethanol in the percolate, make that volatile matter is left in the remaining paste in the plant;
(3) with the paste of collecting in the airtight container of padded, through the jacket steam heating, make volatile substances, through after the cooling system cooling, obtain volatile matter again;
Described plant is the plant that contains volatile matter, as: various plants such as Chinese prickly ash, fennel, elscholtiza, peppermint, sweet osmanthus with volatility medicinal substance.
The inventive method is simple, reliable and stable, easy to operate, yield is high, cost is low, quality is good, wide application, can be effective to from each plant, extract volatile matter, is the innovation of from plant, extracting on the method for volatile matter.
