The method of subcritical fluid extraction boxthorn seed oil
Technical field
The present invention relates to a kind of boxthorn seed oil extracting method, a kind of method particularly relating to subcritical fluid extraction boxthorn seed oil.
Background technology
The wolfberry juice obtained after broken by Fructus Lycii, the Fructus Lycii that particularly obtains after broken with new fresh fructus lycii is fresh squeezes the juice, day at home and abroad Benefit is popular.Existing wolfberry juice in process of production, can obtain the seed of Fructus Lycii containing abundant nutrition composition.Seed of Fructus Lycii through squeezing or Can obtain boxthorn seed oil after the methods such as extraction are refined, seed of Fructus Lycii oil yield is 17%-20%.In boxthorn seed oil containing substantial amounts of not Satisfied fatty acid, VE and phospholipid, the most linoleic content is up to 66.5%, and VE content is 42.02mg/100g, content of phospholipid Being 0.75%, content beta-carotene is 0.73mg/100g, is the vegetable oil of a kind of great health care.Boxthorn seed oil contains There are substantial amounts of nutritional labeling and biological active substances, in addition to having edibility, also medical care effect, may be used for height The auxiliary treatment of the cardiovascular and cerebrovascular diseases such as blood pressure, hyperlipidemia, atherosclerosis.
The extraction of boxthorn seed oil at present mainly uses Mechanical Method, organic solvent method and supercritical fluid extraction.Mechanical expression method Squeezing time length, oil yield is low, impurity content is high, oil quality is poor, and color and luster is deeper;When there is extraction in organic solvent extractionprocess Between long, inefficient, solvent-oil ratio is big, and easily causes in product a series of drawbacks such as dissolvent residual;And supercritical fluid Extraction requires height to instrument and equipment, and technological process is complicated, and volume of equipment is little, cost is high, energy consumption is big, is not suitable for extensive Industrialization continuity produces.
Subcritical fluid extraction technology is to develop the most quick novel extractive technique in the last few years, is also a skill of extraction industry Art revolution.Subcritical fluid extraction technology is to utilize subcritical fluids to hold as extractant, the pressure in airtight, anaerobic, low pressure In device, according to the similar principle mixed of Organic substance, by extraction material and extractant molecule diffusion process in immersion process, Reach in the extractant that the liposoluble constituent in solid material transfers to liquid, then by the process of reduction vaporization by extractant and mesh Product separate, finally give a kind of novel extraction and the isolation technics of purpose product.Extract with traditional solvent extraction and supercritical The technology of taking is compared, and subcritical abstraction had both had supercritical extraction extraction efficiency height, the advantage of product no solvent residue, the most again There is the features such as Conventional solvents extraction equipment cost is low, technological process is simple, production cost is low, and whole extraction process Carry out under conditions of airtight anoxybiotic, low-temp low-pressure, be particularly suitable for similar boxthorn seed oil etc. rich in unsaturated fatty acids acid lipid Industrialization continuity produces.
Summary of the invention
A kind of method that it is an object of the invention to provide subcritical fluid extraction boxthorn seed oil, it can be effectively improved boxthorn seed oil Extraction efficiency, be suitable to industrialized production.
In order to achieve the above object, the technical solution of the present invention is: a kind of method of subcritical fluid extraction boxthorn seed oil, It comprises the steps:
(1) after being squeezed the juice by medlar fresh fruit, the seed of Fructus Lycii of gained dries or dries, and obtains dried wolfberry seed;
(2) by dried wolfberry seed in step (1) and extractant by expecting that molten mass volume ratio is 1: 1~1: 20 to put into Asia and face Continuous extraction 1~20 times in the extraction kettle of boundary's fluid extraction device, each 10~150min, it is extracted thing;
(3) utilize decompression temperature-raising method make extract in step (2) separating pressure be 0.10~1.95MPa, separation temperature Separate under conditions of being 10~90 DEG C, be extracted liquid;
(4) by after the extract left at room temperature 10~90min in step (3), boxthorn seed oil is obtained.
The method of subcritical fluid extraction boxthorn seed oil of the present invention, in wherein said step (2), extractant is propane, butane, different Any one in butane, dimethyl ether, liquefied petroleum gas, HFA 134a.
The method of subcritical fluid extraction boxthorn seed oil of the present invention, in wherein said step (2) extraction conditions be extraction temperature 5~ 85 DEG C, extracting pressure 0.15~2.95MPa, extractant flow 10~200L/h.
After using such scheme, the present invention compared with prior art has the advantage that
1, use the side-product seed of Fructus Lycii in wolfberry juice processing to be raw material due to the present invention, therefore significantly reduce production cost;
2, the present invention uses subcritical fluid extraction and isolation technics, not only significantly reduces production cost, shortens extraction point From the time, decrease solvent-oil ratio and energy consumption in technical process, and technological process is simple, workable, extraction efficiency Height, environmental protection, pollution-free, safety and reproducible, heavy industrialization consecutive production can be realized;
3, carry out under conditions of airtight anoxybiotic, low-temp low-pressure due to whole extraction process, therefore, be particularly suitable for similar Fructus Lycii Seed oil etc. produce rich in the industrialization continuity of unsaturated fatty acids acid lipid;
4, extraction efficiency of the present invention is high, and Extraction solvent can be recycled, with conventional method extract the yield of boxthorn seed oil be 5.7%~ 6.4%, and use the inventive method yield up to 8.0%~9.5%;
5, the boxthorn seed oil of gained of the present invention is faint yellow, and clear shape has the fragrance that boxthorn seed oil is special, and quality is preferable.
