Abstract
The invention provides an extraction method of rose essential oil. The extraction method includes the following steps: picking roses; cleaning and sterilizing; introducing wet air, and obtaining wet air carrying rose essential oil; cooling, removing condensate water, and using an adsorbent for adsorption; extracting for the first time; extracting for the second time; depressurizing for distilling to obtain the rose essential oil. The extraction method is simple, the rose essential oil is extracted from the roses to greatest extent, raw materials are utilized effectively, and production gain is increased directly; the rose essential oil obtained is extremely low in water content, thereby being conducive to storage.
Description
Technical field
The invention belongs to the extractive technique field of essential oil, be specifically related to a kind of extracting method of Flos Rosae Rugosae quintessence oil.
Background technology
Rose, Rosaceae rose fallen leaves bush, its flower, look, perfume (or spice), shape are all beautiful, have high economic worth.Be described as " golden flower ".Flos Rosae Rugosae quintessence oil is the hat of fresh flower oil, has gracefulness, soft, fine and smooth, the fragrant and sweet Rose Essentielle overflowed as honey, fragrance.Fragrance is dense, and namely two can be made into the first-class perfume of 1L, and it is expensive, has the good reputation of " liquid golden ".The extracting method of existing Flos Rosae Rugosae quintessence oil mainly contains:
1, fatty absorption method, utilize the essential oil in grease absorption rose, 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 rose, extraction obtains the mixture of essential oil and organic solvent, and then distillation removing organic solvent, obtains Flos Rosae Rugosae quintessence oil; This kind method extraction of essential oil rate is high, cost is low, but easily causes organic solvent residual, makes Flos Rosae Rugosae quintessence oil fragrance pure not.
3, supercritical extraction, adopt supercritical carbon dioxide fluid to soak, extraction obtains Flos Rosae Rugosae quintessence 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 rose is also extracted out, and moisture content in rose is not easily separated, makes Flos Rosae Rugosae quintessence 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 Flos Rosae Rugosae quintessence oil.
In order to achieve the above object, the invention provides following technical scheme:
An extracting method for Flos Rosae Rugosae quintessence oil, concrete steps are as follows:
(1) full color is selected and the fresh rose of free from insect pests;
(2) by selected fresh rose with 15% salt forever by Rose soak get up to carry out sterilization;
(3) the fresh rose 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 rose 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 rose, obtains the wet air with Flos Rosae Rugosae quintessence oil;
(5) wet air with Flos Rosae Rugosae quintessence oil is lowered the temperature, remove water of condensation, and use adsorbent;
(6) sorbent material being adsorbed with Flos Rosae Rugosae quintessence 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;
(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, obtains second time extract;
(8) underpressure distillation is carried out to the second time extract in step (7), obtain Flos Rosae Rugosae quintessence oil.
As a modification of the present invention, the condition of carrying out first time extraction in described step (6) is: temperature 28-35 DEG C, pressure 15-20MPa, extraction duration 3-8h.
As a modification of the present invention, the condition of carrying out second time extraction in described step (7) is: temperature 30-45 DEG C, pressure 8-10MPa, extraction duration 6-8h.
The invention provides a kind of extracting method of Flos Rosae Rugosae quintessence oil, utilize comparatively simple method to extract Flos Rosae Rugosae quintessence oil from rose to greatest extent, raw material is effectively utilized, directly improves Production Gain; And gained Flos Rosae Rugosae quintessence oil water ratio is extremely low, contribute to carrying out preservation.
Embodiment
Below with reference to specific embodiment, technical scheme provided by the invention is described in detail, following embodiment should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.
