Abstract
The invention discloses a method for extracting Jasminum sambac essential oil. The method comprises the steps of drying Jasminum sambac in the shade, firstly carrying out mechanical activation, then, adding cellulase and water to Jasminum sambac powder, carrying out soaking for 4-6 hours, then, carrying out distillation extraction for 2-3 hours, condensing mixed water vapor obtained through distilling, carrying out oil-water separation on condensed oil-water mixture so as to obtain Jasminum sambac crude oil, and carrying out extractive separation on the Jasminum sambac crude oil, thereby obtaining the Jasminum sambac essential oil. According to the method, mechanical activation treatment and cellulase soaking are carried out firstly before carrying out distillation extraction on the Jasminum sambac essential oil, so that not only is the oil extraction rate increased, but also the distillation time is shortened; and the method further has the advantages of simplicity in operation, low cost, high product purity and the like 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 Flower of Arabian Jasmine essential oil.
Background technology
Flower of Arabian Jasmine, another name: jasmine, Latin literary fame: Jasminumsambac (L.) Ait is Oleaceae gelsemium shrub plant.Flower of Arabian Jasmine essential oil is the essential oil extract from Flower of Arabian Jasmine, and essential oil is 2-4% at the content of Flower of Arabian Jasmine.Flower of Arabian Jasmine essential oil is called as " king of essential oil ".Flower of Arabian Jasmine essential oil yield is few thus very expensive, it has graceful smell, can releive gloomy mood, inspire enthusiasm, promote self-confidence, genial scaly dry skin, lack of water can be nursed simultaneously, cross oil and responsive situation, desalination striae of pregnancy and scar, increase skin elasticity, allow skin feel more tender, in the hot water of bubble pin, instill several Flower of Arabian Jasmine essential oils, the object of channels and collaterals of invigorating blood circulation can be reached.Current Flower of Arabian Jasmine essential oil has been widely used in the fields such as medicine, daily-use chemical industry, food-processing.
The extracting method of Flower of Arabian Jasmine essential 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 Flower of Arabian Jasmine essential oil.In recent years, also have report to use supercritical carbon dioxide process, ultrasonic extraction method Flower of Arabian Jasmine essential 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, for existing Flower of Arabian Jasmine extraction of essential oil Problems existing, provide a kind of method that can improve Flower of Arabian Jasmine essential oil oil 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: dried in the shade by Flower of Arabian Jasmine, adds in agitating ball mill, and mechanical activation 3-5min under rotating speed is 300-500r/min, obtains Flower of Arabian Jasmine powder;
(2) soak: above-mentioned Flower of Arabian Jasmine powder is added retort, add cellulase and water again, the weight of described cellulase is Flower of Arabian Jasmine powder weight 0.6-0.8%, makes water just steep Flower of Arabian Jasmine powder with slabstone pressurization, soak 4-6h at normal temperatures, obtain extracting solution;
(3) distill: pass into water vapour from the bottom of retort and extracting solution is heated, extract 2-3h 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 Flower of Arabian Jasmine and water;
(6) extract: the thick oil of the Flower of Arabian Jasmine obtained extracts through extractor again, after layering, separates upper strata and is Flower of Arabian Jasmine essential oil.
A kind of the above method extracting Flower of Arabian Jasmine essential oil, described agitating ball mill is agitated ball mill.
A kind of the above method extracting Flower of Arabian Jasmine essential oil, the oil yield of described Flower of Arabian Jasmine essential oil is 2.1-2.8%.
A kind of the above method extracting Flower of Arabian Jasmine essential oil, described Flower of Arabian Jasmine essential 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 Flower of Arabian Jasmine essential oil, by Flower of Arabian Jasmine first through mechanical activation process, Flower of Arabian Jasmine 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 of Flower of Arabian Jasmine be more prone to extract, thus improve oil yield.
(2) the present invention is before distillation extraction Flower of Arabian Jasmine essential oil, first use cellulase and water soaking Flower of Arabian Jasmine 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, Flower of Arabian Jasmine essential oil is more easily extracted, not only increase oil yield, also shorten the distillation extraction time.
(3) oil yield of Flower of Arabian Jasmine essential oil of the present invention is 2.2-2.8%, and traditional method oil yield is only 1.5-2.0%.
(4) the thick oil of Flower of Arabian Jasmine after oily water separation of the present invention, first through extracting and separating, improves the purity of product, and the Flower of Arabian Jasmine essential 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.
