Abstract
The invention discloses a method for increasing the extraction ratio of the Sandalwood essential oil. The method comprises the step of drying Sandalwood leaves in the sun, subjecting the dried Sandalwood leaves to the mechanical activation treatment, adding the cellulase and water to soak for 1-3 hours, distilling and extracting after the soaking process for 60-120 minutes, condensing the mixed water vapor obtained through the distilling process, separating the condensed oil-water mixture through the oil-water separation process to obtain the Sandalwood crude oil, extracting and separating the Sandalwood crude oil to obtain the Sandalwood essential oil. According to the technical scheme of the invention, before the distilling and extracting process of the Sandalwood essential oil, the mechanical activation treatment and the cellulase soaking treatment are conducted. In this way, the extraction ratio of the Sandalwood essential oil is improved, and the distillation duration is shortened. The method is simple in operation, low in cost and high in product purity, thus being suitable for industrialized production.
Description
Technical field
The present invention relates to extraction of essential oil field, especially a kind of method improving sandalwood essential oil extraction yield.
Background technology
The heartwood that santal (Santalum album L.) is Santalaceae plant, almug is a kind of semiparasitic plant, and growth is extremely slow, and usually wanting many decades just can become a useful person, is grow one of the slowest seeds, and ripe Tan Shuke is up to ten meters.The root of santal, core, Ye Zhongjun can extract essential oil, and the essential oil content of santal root is 6% ~ 7%, and core essential oil content is then 2% ~ 5%, and leaf essential oil content is 3-4%.Sandalwood essential oil is applicable to aging, dry and lack of water skin, can desalinate scar, microgroove, Glycerin, Ginseng Extract; The calm speciality of tool, can pacify nervous and anxiety, people is loosened, and tool is promoted the sexual maturity characteristic, and efficient kidney tonifying, lax neural, improvement is cold.
Sandalwood essential oil at present widespread use makeup, medicine and other fields, should be used as larger research in recent years to sandalwood essential oil, but less to the extraction research of sandalwood essential oil.In recent years, what sandalwood essential oil extraction the most often used is traditional steam distillation, and traditional steam method is that santal branch, leaf are put into retort straight run distillation, and the mixing steam of distillation obtains oil-water mixture through condensation, oil-water mixture essential oil oily water separation again, can obtain sandalwood essential oil.The problem such as the method exists low, the consuming time length of extraction yield, it is high to consume energy, product purity is low.
Summary of the invention
The object of the invention is to, for sandalwood essential oil extracting method Problems existing, provide a kind of method that can improve sandalwood essential oil extraction yield.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:
(1) mechanical activation: santal leaf is dried, make its water content be 8-12%, then add in agitating ball mill by the santal leaf after drying, mechanical activation 5-10min under rotating speed is 80-120r/min, obtains santal powder;
(2) soak: above-mentioned santal powder is added retort, then adds cellulase and water, the weight of described cellulase is santal powder weight 0.4-0.6%, make water just steep santal powder with slabstone pressurization, soak 1-3h at normal temperatures, obtain extracting solution;
(3) distill: pass into water vapour from the bottom of retort and extracting solution is heated, extract 80-120min 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 santal and water;
(6) extract: the thick oil of the santal obtained extracts through extractor again, separates upper strata and is sandalwood essential oil.
A kind of the above method improving sandalwood essential oil extraction yield, the extraction rate reached of described sandalwood essential oil is to more than 92%.
A kind of the above method improving sandalwood essential oil extraction yield, described sandalwood essential oil purity reaches more than 97%.
Compared with prior art, the beneficial effect that the present invention obtains is:
(1) the present invention is before distillation extraction sandalwood essential oil, santal leaf is dried rear first through mechanical activation process, santal leaf 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 the essential oil in santal leaf be more prone to extract, thus improve the extraction yield of essential oil.
(2) the present invention is before distillation extraction sandalwood essential oil, santal leaf first uses cellulase and water soaking, the cellulose skeleton of composition cell walls can be degraded into glucose by cellulase step by step, and then destroy cell wall skeleton structure, sandalwood essential oil is more easily extracted, not only increase the extraction yield of essential oil, also shorten the distillation extraction time.
(3) extraction rate reached of sandalwood essential oil of the present invention is to 92%, and existing wet distillation method extraction yield only reaches about 85%.
(4) the thick oil after oily water separation of the present invention, first through extracting and separating, improves the purity of product, and the sandalwood essential oil purity obtained reaches more than 97%, and traditional vapor extraction 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.
