Description
Technical field
The present invention relates to Vegetable oil lipoprotein extractive technique field, particularly relate to a kind of subcritical fluid extraction Quinoa seed oil
Method.
Background technology
Quinoa is a kind of staple food grain of South America Andean region time-honoured, mainly plants and pacifies in Peru and Bolivia etc.
The country in this area, also begins to plantation on the Tibet of China, Shanxi, Qinghai and other places.In order to publicize the nutritive value of Quinoa, connection
Close state and once announce 2013 for " international Quinoa year ".Due to its outer image corn, sometimes referred to as " pseudo-corn ", but the most again
" pseudo-oil plant " it is referred to as because its fat content is higher.
Quinoa mouthfeel is the finest and the smoothest, with nut taste and the fragrance of earth.Quinoa contains Saponin, generally passes through at before sales
Machinery means by removing, or carefully rinse before boiling, to remove bitterness.According to saponin content height, Quinoa kind has
Dividing of " bitter ", " sweet ".The intravarietal saponin content of sweet Quinoa is the lowest.
The variety diversity of Quinoa, can-4 to 35 degrees Celsius temperature range, from sea level to height above sea level 4000 meters with
Under space in grow.Some kind has drought-enduring and salt tolerant characteristic, can grow under severe conditions, and planting cost is low, right
The utilization ratio of water is high.
The nutritive value of Quinoa is the highest, is a kind of health food.Quinoa and most of other plant group foods (do not include bean
Class) difference be that its protein content is higher.Quinoa can provide all necessary aminoacid, and content equalizes, and rich
Containing mineral, vitamin, fatty acid and other nutritional labelings, it it is the good source of heat energy and dietary fiber.
Whole plant of Quinoa is used as greenfeed, and the stubble after results can also be used for raising of cattle, sheep, pig, horse and poultry
Material；Traditionally the aborigines of Andean region the base of leaf of Quinoa and seed are used for healing of wound, subside a swelling, releive toothache and urethra
Sterilization, is also used for boneseting, treating internal hemorrhage and anthelmintic；The protein concentrate of Quinoa can be used for the mankind or Animal nutrition supplement
Dispensing；The Saponin extracted from bitter Quinoa can induce change gut permeability, promotes the absorption of certain drug, and Saponin is due to energy shape
Foam is become to can be used for, in detergent, toothpaste, shampoo, also having the potentiality of insecticide；Quinoa starch has fabulous freeze thawing
Stability, can be as the succedaneum of converted starch.
In Quinoa seed, fat average content is 50～72 mg/g, is about 2 times of Semen Maydis, is largely focused on seed
In, its composition is similar to Semen Maydis.Wherein triglyceride accounts for more than 50%, and diglyceride spreads all over whole kernel and accounts for neutral lipid
The 20% of content, and lysophosphatide LYSO-PHOSPHATIDYLCHOLINE LYSOPC accounts for 57%.In Quinoa oils and fats rich in unsaturated fatty acid mostly be ω-3
With ω-6.ω-3 and ω-6 unsaturated fatty acid major part contain carbon-carbon double bond, including linoleic acid, linolenic acid, arachidonic acid,
It it is all the fatty acid of needed by human.Linoleic acid can be metabolised to arachidonic acid, and linolenic acid can be metabolised to eicosapentaenoic acid
(eicosapentaenoic acid, EPA) and docosahexenoic acid (docosahexaenoic acid, DHA).EPA and
Preventing and treating prostaglandin, thrombosis, atherosclerosis, immunity, antiinflammatory and film function are played an important role by DHA.Richness in Quinoa oils and fats
Containing unsaturated fatty acid, belong to high-quality oils raw material.
In fruit, the extraction of oils and fats mainly uses Mechanical Method, organic solvent method and supercritical fluid extraction at present.Machine
Tool milling process squeezes time length, oil yield is low, impurity content is high, oil quality is poor, and color and luster is deeper；Organic solvent extractionprocess exists
Extraction time length, inefficient, solvent-oil ratio is big, and easily causes in product a series of drawbacks such as dissolvent residual；And surpass and face
Boundary's fluids 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 big
Technical scale consecutive production.
Subcritical fluid extraction technology is to develop the most quick novel extractive technique in the last few years, is also extraction industry
One field technology revolution.It refers to that extractant is consistently lower than its critical pressure (Pc) and critical temperature (Te) in extraction process, begins
It is the extraction process of fluid liquid eventually.Compared with traditional solvent extraction and supercritical extraction technique, subcritical abstraction had both had super
Critical extraction extraction efficiency is high, the advantage of product no solvent residue, has again Conventional solvents extraction equipment simultaneously and makes
The features such as valency is low, technological process is simple, production cost is low, and whole extraction process is in airtight anoxybiotic, the condition of low-temp low-pressure
Under carry out, be particularly suitable for similar Quinoa seed oil etc. and produce rich in the industrialization continuity of unsaturated fatty acids acid lipid.
The technical problem to be solved is to provide and a kind of is effectively improved extraction efficiency, is suitable to the Asia of industrialized production
The method of supercritical fluid extraction Quinoa seed oil.
Summary of the invention
For solve the problems referred to above, a kind of subcritical fluid extraction Quinoa seed of the present invention oil method, including with
Lower step:
(1) will remove Quinoa seed dry in the sun or the drying of episperm, remove the removal of impurity and moldy kernel, obtain selected after go
Except the Quinoa seed of seed coat；
(2) the Quinoa seed in step (1) and extractant are put into sub-critical flow by the molten mass volume ratio of material of 1: 1～1: 2
Continuous extraction 1～5 times in the extraction kettle of body extraction equipment, each 10～90min, it is extracted thing；
(3) utilize decompression temperature-raising method make extract in step (2) separating pressure be 0.10～1.00MPa, separation temperature be
Separate under conditions of 30～90 DEG C, be extracted liquid；
(4) by after the extract left at room temperature 10～120min in step (3), Quinoa seed oil is obtained.
Extractant in described step (2) refers to dimethyl ether and fatty alcohol-polyoxyethylene ether, fatty acid methyl ester polyoxyethylene
The mixture of the nonionic surfactant such as ether, polyol type, dimethyl ether is 100 with the ratio of nonionic surfactant:
0.02~0.5。
In described step (2), extraction conditions refers to that extraction temperature is 25～70 DEG C, and extracting pressure is 0.15～1.50MPa,
Extractant flow is 10～100L/h.
The present invention compared with prior art has the advantage that
1, the present invention uses Quinoa seed to be that raw material extracts Quinoa seed oil, and its residue can be further used for extracting separation Herba chenopodii
The highly enriched albumen of wheat, makes full use of the nutritional labeling of the inside, improves economic benefit；
2, the present invention uses subcritical fluid extraction and isolation technics, not only significantly reduces production cost, shortens extraction
Disengaging time, decreases solvent-oil ratio and energy consumption in technical process, and technological process is simple, workable, extraction effect
Rate is high, environmental protection, pollution-free, safety and reproducible, can realize heavy industrialization consecutive production；
3, carry out under conditions of airtight anoxybiotic, low-temp low-pressure due to whole extraction process, therefore, be particularly suitable for similar Quinoa
Seed oil etc. produce rich in the industrialization continuity of unsaturated fatty acids acid lipid；
4, the present invention adds nonionic surfactant in extractant, improves extraction efficiency, extract yield up to 4.8%～
6.5%, Extraction solvent can be recycled；
5, the Quinoa seed breakdown of oil of gained of the present invention is transparent, has the fragrance that Quinoa seed oil is special, and quality is preferable.
