Abstract
The invention discloses a method for extracting clove oil. The method comprises the following steps: drying clove buds in the sun, mechanically activating, adding cellulase and water, immersing for 4-6h, carrying out distilling extraction for 1.5-2h, condensing mixed water steam obtained after distillation, carrying out oil-water separation on a condensed oil and water mixture to obtain crude clove oil, and carrying out extracting separation on the crude clove oil to obtain the clove oil. Mechanical activation treatment and immersion in cellulase are carried out before distilling extraction of the clove oil, so the oil yield is improved, and the distillation time is shortened; and the method also has the advantages of simple operation, low cost and high product purity, and is very suitable for industrial production.
Description
Technical field
The present invention relates to extraction of essential oil field, especially a kind of method extracting Syzygium aromaticum stem oil.
Background technology
Cloves (EugeniacaryophllataThunb.) is Myrtaceae Syzygium arbor cloves.Syzygium aromaticum stem oil is the essential oil extract from cloves bud, can treat toothache, bronchitis, neurodynia, hydrochloric acid in gastric juice, anti-respiratory system and urinary system infection, alleviate discomfort and pain that dysentery causes, improve weak physique and anaemia, promote the sexual maturity (sexual dysfunction, creeping chill), expelling parasite.Stimulate circulation, treatment skin ulcer and wound inflammation, treatment mange, improves coarse skin.Be widely used in the field such as medical and health, daily-use chemical industry at present.
The extracting method of Syzygium aromaticum stem oil is mainly steam distillation, organic solvent method, there is the problems such as low, the consuming time length of extraction yield, product purity be low in existing water vapour, solvent method not only needs to remove extracting solvent, also can make there is a large amount of residual solvent in product, thus have impact on smell and the purity of Syzygium aromaticum stem oil.In recent years, also have report to use supercritical carbon dioxide process, ultrasonic extraction method Syzygium aromaticum stem oil, but these two kinds of methods to there is equipment cost high, be difficult to realize suitability for industrialized production.
Summary of the invention
The object of the invention is to extract Problems existing for existing Syzygium aromaticum stem oil, a kind of method extracting Syzygium aromaticum stem oil is provided.Not only extraction yield is high for the method, product purity is high, also has that cost is low, consume energy low, the advantage such as extraction time is short.
In order to realize above object, the present invention is achieved by the following technical solutions:
Extract a method for Syzygium aromaticum stem oil, comprise the following steps:
(1) mechanical activation: dried by cloves bud, adds in agitating ball mill, and mechanical activation 3-5min under rotating speed is 300-500r/min, obtains cloves powder;
(2) soak: above-mentioned cloves powder is added retort, then adds cellulase and water, the weight of described cellulase is cloves powder weight 0.5-0.8%, make water just steep cloves powder with slabstone pressurization, soak 3-6h at normal temperatures, obtain extracting solution;
(3) distill: pass into water vapour from the bottom of retort and extracting solution is heated, extract 1.5-2h after extracting solution boiling, obtain mixing steam;
(4) condensation: mixing steam obtained above carries out condensation through condenser, obtains oil-water mixture after condensation;
(5) oily water separation: the oil-water mixture that condensation obtains carries out oily water separation through water-and-oil separator, obtains the thick oil of cloves and water;
(6) extract: the thick oil of the cloves obtained extracts through extractor again, after layering, separates lower floor and is Syzygium aromaticum stem oil.
A kind of the above method extracting Syzygium aromaticum stem oil, described being dried by cloves of step (1) is dried by cloves bud to make its water content be 5-8%.
A kind of the above method extracting Syzygium aromaticum stem oil, described agitating ball mill is agitated ball mill.
A kind of the above method extracting Syzygium aromaticum stem oil, the oil yield of described Syzygium aromaticum stem oil is 20-24%.
A kind of the above method extracting Syzygium aromaticum stem oil, described Syzygium aromaticum stem oil purity reaches more than 98%.
Compared with prior art, the beneficial effect that the present invention obtains is:
(1) the present invention is before distillation extraction Syzygium aromaticum stem oil, by cloves raw material first through mechanical activation process, cloves is destroyed the cell walls of plant by mechanical activation under the mechanical force such as friction, collision, impact, shearing, and make grain refine, make essential oil be more prone to extract from cloves bud, thus improve oil yield.
(2) the present invention is before distillation extraction Syzygium aromaticum stem oil, first use cellulase and water soaking cloves raw material, the cellulose skeleton of composition cell walls can be degraded into glucose by cellulase step by step, and then destroy cell wall skeleton structure, Syzygium aromaticum stem oil is more easily extracted, not only increase oil yield, also shorten the distillation extraction time.
(3) oil yield of Syzygium aromaticum stem oil of the present invention is 11-13%, and traditional steam method oil yield is only 15-18%.
(4) the thick oil of cloves after oily water separation of the present invention, first through extracting and separating, improves the purity of product, and the Syzygium aromaticum stem oil purity obtained reaches more than 98%, and existing extracting method purity generally only reaches 90%.
(5) the inventive method also have simple to operate, extraction time is short, low cost and other advantages, is applicable to suitability for industrialized production.
