Abstract
The invention relates to a method for abstracting pomelo peel essential oil from pomelo peel. Firstly the pomelo peel dried in shade is crushed, then is sieved for 40 meshes, then hydrophilic ion liquid is added into the pomelo peel, the mass-volume ratio of the pomelo peel and the hydrophilic ion liquid is 1:2 to 20 (g:ml), then the microwave heating is performed until the pomelo peel is completely dissolved, the frequency of the microwave is 2450 MHz, then conventional water vapour distillation method is adopted to extract the pomelo peel essential oil, the microwave heating temperature is at 80 to 120 DEG C, and the hydrophilic ion liquid is an arbitrary one of [BMIM]AcO, [BMIM]Cl or [AMIM]Cl. The invention has the advantages: firstly, the preparation method is simple, the prepared pomelo peel essential oil has good quality and higher yield, and the yield rate of the pomelo peel essential oil prepared through the method is about 18 to 25 percent higher than the yield rate of the pomelo peel essential oil directly prepared through the water vapour distillation method; secondly, the adopted hydrophilic ion liquid can be recovered and circularly used through adopting ion exchange method, and basically the environmental pollution can not be caused.
Description
Technical field
The present invention relates to a kind of method of from shaddock ped, extracting the shaddock ped essential oil.
Background technology
Teak in China as cultivation of fruit tree, distributed more widely.For a long time, the shaddock ped resource fails to obtain good development and utilization, and extracting the shaddock ped essential oil by shaddock ped is a kind of effective way of shaddock ped recycling.The shaddock ped essential oil is a kind of lurid oily liquids with happy fragrance, is widely used in food and drink industry.Extract the shaddock ped essential oil by shaddock ped at present and mainly adopt steam distillation, organic solvent extractionprocess and supercritical extraction, wherein steam distillation is most widely used, and it is good to obtain shaddock ped essential oil quality, but yield is lower.
Hydrophilic ionic liquid is a collection of organic liquid material of at room temperature being made up of ion fully, than organic solvent commonly used, because it is non-volatile, can recycle, and is considered to green solvent.Do not see at present that hydrophilic ionic liquid is used for being extracted by shaddock ped the report of shaddock ped essential oil.
Summary of the invention
Problem to be solved by this invention is to propose a kind of method of extracting the shaddock ped essential oil from shaddock ped at above-mentioned prior art, and shaddock ped essential oil quality obtained by this method is good, and the essential oil productive rate is significantly improved.
The present invention for the solution that problem adopts of the above-mentioned proposition of solution is: a kind of method of extracting the shaddock ped essential oil from shaddock ped, its difference is that the shaddock ped that at first will dry in the shade pulverizes, pulverize the back and cross 40 mesh sieves, then to wherein adding hydrophilic ionic liquid, described shaddock ped and hydrophilic ion liquid mass volume ratio are 1: 2-20 (g: ml), adopt microwave heating to shaddock ped to dissolve fully again, described microwave frequency 2450MHz adopts conventional steam distillation to extract then and obtains the shaddock ped essential oil.
Press such scheme, described microwave heating temperature is 80～120 ℃.
Press such scheme, described hydrophilic ionic liquid is [BMIM] AcO, any one among [BMIM] Cl or [AMIM] Cl.
Advantage of the present invention:
1) preparation method is simple, and it is good to obtain shaddock ped essential oil quality, and yield is higher, and is higher by about 18～25% than the productive rate of direct employing steam distillation;
2) adopt hydrophilic ionic liquid can adopt the ion exchange method recycling use, can not cause environmental pollution substantially.
