Description
Technical field
The invention belongs to the extractive technique field of essential oil, be specifically related to a kind of extracting method of osmanthus essential oil.
Background technology
Sweet osmanthus has another name called sweet-scented osmanthus, orange osmanthus, rock osmanthus, belongs to Oleaceae evergreen shrubs or arbor, Gao Keda 10 meters.Tree crown spheroidal.Trunk is coarse, canescence.Leaf keratin, to life, oval or oblong, there is sawtooth at spire edge.Flowers are raw, are born in axil for 3 one 5, many are born in the spring tip then, and two, three years raw branches also have life, and corolla divides has milky white, yellow, orange red isochrome to base breast, and fragrance is extremely dense.The kind of sweet osmanthus is a lot, common are four kinds: Jin Gui, silver-colored osmanthus, orange osmanthus and Osmanthus fragans.Fruit is atropurpureus drupe, is commonly called as Gui Zi.
Sweet osmanthus originates in Southwestern China and middle part, existing extensively plants in the Yangtze valley and areas to the south, the weather of happiness warm and moist, high temperature resistant and do not resist cold, and is temperate zone seeds.Sweet osmanthus is full of leaves and evergreen, and the age of tree is permanent, fall flowering, and sweet perfumes are diffused all around, is ornamencal flower and tree and the fragrance tree of China's special product.Population in Xianning, Hubei Province is planted a lot of in flakes, is the township of sweet osmanthus.Chengdu, Hangzhou, Guilin are also that orange osmanthus grows into forest, and afford a magnificent spectacle.Cassia tree is wooden fine and closely woven tough and tensile, has multiple use.The pungent temperature of Ou Luya bay-oil smell, nontoxic, be used as medicine have reduce phlegm, cough-relieving, promote the production of body fluid, only effect such as toothache.The strong fragrant grace of fragrance, middle people are as liquor-saturated.
Osmanthus essential oil is generally comparatively large to extract in flavous golden osmanthus by spending, instead of our silver-colored osmanthus of white little Hua of usually seeing, is to spend middle extraction with solvent method from golden osmanthus.Osmanthus essential oil has to headache, fatigue the effect slowed down, and is also that splendid mood rouses oneself agent simultaneously.Rheumatism, arthralgia can also be treated.Osmanthus essential oil is also best air freshener, no matter be fumigate or be mixed in water to be sprayed at indoor, is all the good selection regulating air.The extracting method of existing osmanthus essential oil mainly contains:
1, fatty absorption method, utilize the essential oil in grease absorption sweet osmanthus, although technique is simple, later separation essential oil and grease are comparatively difficult.
2, extraction, adopt low boiling point solvent such as the organic solvent such as sherwood oil, hexane to soak sweet osmanthus, extraction obtains the mixture of essential oil and organic solvent, and then distillation removing organic solvent, obtains osmanthus essential oil; This kind method extraction of essential oil rate is high, cost is low, but easily causes organic solvent residual, makes osmanthus essential oil fragrance pure not.
3, supercritical extraction, adopt supercritical carbon dioxide fluid to soak, extraction obtains osmanthus essential oil; This kind of method has the high and high quality of yield; But because supercritical carbon dioxide fluid solvability is too strong, the non-derived essential oil in sweet osmanthus is also extracted out, and moisture content in sweet osmanthus is not easily separated, makes osmanthus essential oil easy mildew in the process of storage, limits the range of application of products obtained therefrom.
Therefore, develop a kind of technique comparatively simple, and essential oil pick-up rate is high, can reduce essential oil water content, the method being suitable for preservation is those skilled in the art institute urgent need to solve the problem simultaneously.
Summary of the invention
For solving the problem, the invention discloses a kind of extracting method of osmanthus essential oil.
In order to achieve the above object, the invention provides following technical scheme:
An extracting method for osmanthus essential oil, concrete steps are as follows:
(1) flower is selected comparatively large in flavous fresh sweet osmanthus;
(2) by selected fresh sweet osmanthus with 15% salt forever sweet osmanthus immersion is got up to carry out sterilization;
(3) the fresh sweet osmanthus layering after sterilized is overlayed gas in food steamer and steam 1-2min, food steamer internal pressure keeps 0.1-0.12MPa, and temperature keeps 105-106 DEG C.
(4) the sweet osmanthus layering after being steamed by gas is positioned on flower stand, and by induced draft fan, wet air air-flow is introduced flower stand, and by sweet osmanthus, obtains the wet air with osmanthus essential oil;
(5) wet air with osmanthus essential oil is lowered the temperature, remove water of condensation, and use adsorbent;
(6) sorbent material being adsorbed with osmanthus essential oil in step (5) is sent in supercritical extraction reactor, be that extraction fluid carries out first time extraction with carbonic acid gas, obtain first time extract, extraction conditions is: temperature 22-28 DEG C, pressure 10-12MPa, extraction duration 2-6h.
(7) the first time extract obtained in step (6) is put into supercritical extraction reactor again, the carbonic acid gas taking dehydrated alcohol as entrainment agent is carried out second time extraction as extraction fluid, obtain second time extract, extraction conditions is temperature 20-28 DEG C, pressure 5-8MPa, extraction duration 3-5h.；
(8) underpressure distillation is carried out to the second time extract in step (7), obtain osmanthus essential oil.
The invention provides a kind of extracting method of osmanthus essential oil, utilize comparatively simple method to extract osmanthus essential oil from sweet osmanthus to greatest extent, raw material is effectively utilized, directly improves Production Gain; And gained osmanthus essential oil water ratio is extremely low, contribute to carrying out preservation.
