Description
Technical field
The present invention relates to vegetable oil extractive technique field, especially a kind of method for extracting tea-seed oil.
Background technology
Tea-seed oil is to extract and obtain from the fruit of Theaceae Camellia Plants oil tea, and color is pale yellow, clear, gas
Taste delicate fragrance.Tea-seed oil is the distinctive grease in China, its aliphatic acid composition and the best vegetable fat olive oil generally acknowledged in the world
It is similar, in tea-seed oil without indigestibility absorb component, unsaturated fatty acid content more than 90%, and rich in vitamin A, B,
D, the several functions composition such as E, there is the effect of angiocardiopathies such as preventing hypertension, coronary heart disease, atherosclerosis.
Traditional tea-seed oil preparation method is milling process or extraction method, and the tea-seed oil crude oil color and luster that milling process is produced is deep
And it is muddy, and Residual oil is higher in oil cake after oil expression；Extraction method needs the process of precipitation, and processing cost is larger, and solvent
Remain and worried by many consumers.Meanwhile both approaches are required to numerous and diverse post processing subtractive process, required equipment is more,
Energy consumption is big, and is difficult to the product for obtaining high-quality.Complex process, high energy consumption, the tea seed of extraction with reference to existing for both approaches
The problem of oil quality difference, more researchers attempt to look for that a kind of technique is simple, energy consumption is low, tea seed oil quality is preferably square
Method.
The content of the invention
It is an object of the invention to provide a kind of method for extracting tea-seed oil, the method for this extraction tea-seed oil can solve work
Skill complexity, high energy consumption, the ropy problem of tea-seed oil of extraction.
In order to solve the above problems, the technical solution adopted by the present invention is：
The method of this extraction tea-seed oil comprises the following steps：
A, after fresh tea seed is removed the peel, selection nothing is gone mouldy, the tea seed of no disease and pests harm, and it is 65 DEG C~75 DEG C to set temperature, is dried
40 minutes~80 minutes；
B, by the tea seed broken shell after drying, by Kernel-hull separation, camellia seed kernel is collected, is crushed, cross the mesh molecular sieve of 70 mesh~100,
Obtain tea seed powder；
C, tea seed powder is immersed in the container for filling petroleum ether, be ultrasonically treated 20 ~ 40 minutes；
D, step C products therefrom is transferred in the apparatus,Soxhlet's for filling petroleum ether, adjusts the temperature to 40 DEG C~85 DEG C, backflow carries
Take 3 hours~7 hours, collect phegma；
E, the phegma is subjected to decompression rotary evaporation, setting pressure is 0.07 ~ 0.1MPa, temperature during evaporation for 30 DEG C~
50 DEG C, obtain crude extract；
F, the sodium-chloride water solution that mass percent is 5% ~ 18% is added into the crude extract, is carried with steam extraction device
Take 4~7 hours, obtain thick tea-seed oil；Wherein, the volume for the NaC aqueous solutions that every 100 grams of crude extracts add is 1 liter~1.2
Rise.
In above-mentioned technical proposal, more specifically scheme can also be：Sonication treatment time is 25 minutes~35 minutes.
Further, pressure during vacuum distillation is 0.083Mpa.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, steam extraction method of the present invention, equipment is simple and convenient to operate, cost is cheap, but single steam extraction method
Recovery rate is relatively low, and combines ultrasonic wave extraction of the present invention, surname extraction, the method being evaporated under reduced pressure, the tea-seed oil purity extracted
It is higher, without impurity such as carbohydrate, protein and pigments, also without organic solvent residual；Without follow-up numerous and diverse treatment process, institute
Tea-seed oil is of light color, quality is pure, A sweety scent assails the nostrils, extraction rate reached 92.58%.
2nd, the present invention is to the less demanding of equipment, and easily controllable, and workable, power consumption is low, suitable for tea-seed oil
Large-scale processing.
