Abstract

The invention discloses a method for extracting gardenia essential oil, the method for extracting gardenia essential oil comprises the steps of putting fresh gardenia in a transparent thin-film sealing box with a built-in ultraviolet lamp, performing irradiation; when water loss of the gardenia is about 75-85%, stopping irradiation, taking out the gardenia and putting to a fine rack; putting gardenia particles after being turned and sieved to a constant-temperature furnace; drying the particles for 1-2h at 35-40 DEG C under protection of nitrogen; quickly cooling the particles, performing freeze-drying for 30-50s at -10 to -20 DEG C; putting the product to the constant-temperature furnace, drying the product for 6-7h at 65-75 DEG C; putting dried gardenia to water in which mass is 3 times of the gardenia; using ultrasonic wave to perform washing; using washed solution as extraction liquid to performance Soxhlet extraction, compression and condensation for the dried gardenia. The method is achieved without high pressure and organic solvent and has the advantages of good flavor, high yield and the like.

Description

A kind of extracting method of flower of Capa Jasmine essential oil liquid
Technical field
The present invention relates to a kind of method of extracting natural spice essential oil liquid, particularly a kind of extracting method of flower of Capa Jasmine essential oil liquid.
Background technology
Flower of Capa Jasmine is a kind of famous and precious natural perfume, and its contained effective constituent flower of Capa Jasmine essential oil liquid in various products, has heat-clearing and fire-purging, treatment pyreticosis as high-grade fragrance applications, eases off the pressure, the effect of moisturizing skin.The existing method of extracting flower of Capa Jasmine essential oil liquid is that bright flower of Capa Jasmine is made gardenia concrete with the sherwood oil lixiviate, adds 3~6 times of ethanol, cold filtration, remove insoluble wax, and then be cooled to-15~25 ℃, and refiltering paraffin removal, ethanolic soln is removed ethanol through underpressure distillation, namely obtain essential oil liquid, yield is generally 0.05~0.06%, and the shortcoming of this method is that fragrance is relatively poor, and color is darker, yield is lower, and residual organic solution can produce detrimentally affect to human body.
In addition, the eighties, supercritical carbon dioxide extraction method also was widely used for the extraction of spices, supercritical carbon dioxide extraction be carbonic acid gas under the supercritical state as solvent, utilize its hypertonicity and high-solvency to extract the process of separating mixture.Supercritical carbon dioxide extraction method has that environment is good, operational safety, do not have that pest is residual, product quality is high and can keep the characteristics such as intrinsic smell, still need to carry out conditional request height, complex manufacturing process in making processes under hyperpressure.
Summary of the invention
The present invention is directed to through the sherwood oil dipping, the essential oil fragrance that extraction using alcohol obtains is relatively poor, color is dark, yield is lower, debris produces detrimentally affect to human body; And supercritical carbon dioxide extraction needs the problems such as hyperpressure, and a kind of extracting method of flower of Capa Jasmine essential oil liquid is provided, and the method does not need high pressure and fragrance is good, yield is high, exist without organic residue liquid.
Technical scheme of the present invention is:
A kind of extracting method of flower of Capa Jasmine essential oil liquid, its method is:
(1) transparent film watertight chest of self-control, built-in 30~50W ultraviolet lamp;
(2) pluck fresh flower of Capa Jasmine 3~8kg in watertight chest, use ultra violet lamp 5~6 hours, treat that flower of Capa Jasmine withers, percentage of water loss is about 75~85%, stops illumination;
(3) take out and to put into fine fack, rear static with constantly roll convolution and stirring up and down of hand, 6~8 times so repeatedly, sieve;
(4) the flower of Capa Jasmine particle after will sieving was put into constant temperature oven, under the nitrogen protection condition under 35~40 ° of C dry 1~2 hour; Then rapidly cooling be lyophilize 30~50 seconds under-10~-20 ° of C in temperature, and putting into constant temperature oven is drying 6~7 hours under 65~75 ° of C in temperature again;
The flower of Capa Jasmine of (5) getting after the above-mentioned part drying treatment is still in the water of 3 times of quality, washs under hyperacoustic effect 2~4 hours;
(6) solution after the washing carried out Soxhlet extraction 6~7 hours as extract to the flower of Capa Jasmine of residue after the drying treatment, and concentrating under reduced pressure can obtain pure gardenia absolute liquid.
Described fine fack intermittently is 3~5mm.
Described quality for the flower of Capa Jasmine after the part drying treatment of supersound washing accounts for 20~30% of flower of Capa Jasmine total mass.
The innovation that the present invention compared with prior art has is;
(1) the flower of Capa Jasmine washings after to process need not to add new organic solvent as extract, has improved the quality of gardenia absolute;
(2) need not to extract with supercutical fluid under the condition of high voltage, is that extract directly extracts by means of the flower of Capa Jasmine after processing under the specified conditions;
(3) irradiation of introducing UV-light not destroying under the original material conditions of flower of Capa Jasmine, dries out it, and charing is conducive to the separation of inner organic substance.
Embodiment
A kind of extracting method of flower of Capa Jasmine essential oil liquid, its method is:
(1) transparent film watertight chest of self-control, built-in 30~50W ultraviolet lamp;
(2) pluck fresh flower of Capa Jasmine 3~8kg in watertight chest, use ultra violet lamp 5~6 hours, treat that flower of Capa Jasmine withers, percentage of water loss is about 75~85%, stops illumination;
(3) take out and to put into fine fack, rear static with constantly roll convolution and stirring up and down of hand, 6~8 times so repeatedly, sieve;
(4) the flower of Capa Jasmine particle after will sieving was put into constant temperature oven, under the nitrogen protection condition under 35~40 ° of C dry 1~2 hour; Then rapidly cooling be lyophilize 30~50 seconds under-10~-20 ° of C in temperature, and putting into constant temperature oven is drying 6~7 hours under 65~75 ° of C in temperature again;
The flower of Capa Jasmine of (5) getting after the above-mentioned part drying treatment is still in the water of 3 times of quality, washs under hyperacoustic effect 2~4 hours;
