Description
Technical field
The present invention relates to vegetable oil to extract field, is concretely the method for supercritical carbon dioxide extracting Seabuckthorm Seed Oil.
Background technology
Sea-buckthorn, also known as vinegar willow, Hei Ci and acid thorn etc., are extremely strong more of a kind of resistance to dry cold, saline-alkali tolerant, impoverishment tolerant, vitality
Year raw shrub or dungarunga fruit tree.Sea-buckthorn is the current precious nonwood forest trees containing natural complex most species in the world,
Its ascorbic content is significantly larger than fresh dates and Kiwi berry, so as to be known as the treasure-house of natural complex.
The plant extract of seabuckthorn seeds is a variety of by palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, leukotrienes etc.
Beneficial fatty acids form, and wherein unrighted acid is up to 75%, and Seabuckthorm Seed Oil is rich in vitamin E, vitamin B1, vitamin
B2, vitamin B6, alpha-tocopherol, carotenoid etc..The extraction of seabuckthorn seeds at present mainly uses mechanical pressing method and organic solvent
Method, the mechanical pressing method squeezing time is long, oil yield is low, impurity content is high, oil quality is poor, and color and luster is deeper, organic solvent extraction
Method is long, inefficient there are extraction time, and loss of effective components is larger, and solvent-oil ratio is big, and it is residual to easily cause solvent in product
The series of malpractice such as stay.
Some Enterprises extract seabuckthorn seeds using conventional Supercritical carbon dioxide, extraction when seabuckthorn seeds waste material according to
So contain a large amount of Seabuckthorm Seed Oils, although existing than mechanical pressing method and organic solvent method on solvent-oil ratio and dissolvent residual
It is progressive, but can not still solve inefficient, the problem of loss of effective components is larger.
Therefore need one kind to be based on supercritical carbon dioxide, in combination with Seabuckthorm Seed Oil caused by extraction, pass through sea-buckthorn
Seed oil is dissolved and extracted to not extracting lipid phase in seabuckthorn seeds, and the overcritical titanium dioxide of overall effect of extracting is substantially improved
The method that carbon extracts Seabuckthorm Seed Oil.
The content of the invention
No matter the present invention uses mechanical pressing method, organic solvent method and conventional Supercritical in being extracted for existing Seabuckthorm Seed Oil
There is the problem of Seabuckthorm Seed Oil yield being finally obtained by extraction is not high, and beneficiating ingredient content is low in carbon dioxide extraction method, there is provided
A kind of method of supercritical carbon dioxide extracting Seabuckthorm Seed Oil.
The present invention solves above-mentioned technical problem, and the technical solution of use is, supercritical carbon dioxide extracting Seabuckthorm Seed Oil
Method, comprises the following steps：

Optionally, in the 5th step, the carbon dioxide separated in separating still is imported to extraction again after overcompression
Kettle is taken to recycle.
The purpose so designed is, by carbon dioxide that will be discharged after use and from separating still through overcompression
Import in extraction kettle and recycle again afterwards, carbon dioxide-depleted can be reduced, so as to reduce production cost.
Further, in the 6th step, it is dry 2h in 60 DEG C~80 DEG C baking ovens that part B seabuckthorn seeds are put into temperature, and is passed through
Seabuckthorn seeds water content is 3%~5% after drying, and seabuckthorn seeds mesh number is 70~90 mesh after crushing.
The purpose so designed is that the present invention is mainly by supercritical carbon dioxide extracting and organic solvent extraction phase knot
Close, grease in seabuckthorn seeds, while the Seabuckthorn Oil that will be extracted in part A seabuckthorn seeds are extracted using supercritical carbon dioxide lipophilicity
Fat is put into extraction kettle, also can to grease is similar in part B seabuckthorn seeds mixes, improve the yield of final Seabuckthorm Seed Oil, reduce extraction
Take Seabuckthorm Seed Oil content in waste material.
Further, in the 7th step, seabuckthorn seeds extract A and part B seabuckthorn seeds are uniformly mixed by blender, and it is quiet
Put 2~3h.
The purpose so designed is, by by seabuckthorn seeds extract A with and part B seabuckthorn seeds mix and stand, can be with
Come into full contact with easy to organic solvent seabuckthorn seeds extract A and grease in part B seabuckthorn seeds, easy to subsequently extract.
Optionally, in the 8th step, extraction temperature is 70 DEG C~80 DEG C, and pressure is 1.5~2.2Mpa, and carbon dioxide flow rate is
0.15~0.18L/min, extraction time are 4~5h.
The purpose so designed is, based on for part A seabuckthorn seeds and part B seabuckthorn seeds extraction purpose difference, part A
Seabuckthorn seeds extraction is used to make seabuckthorn seeds extract A, and the extraction of part B seabuckthorn seeds is used to obtain final Seabuckthorm Seed Oil, takes difference
Extraction parameters extracted, effect of extracting can be improved.
Optionally, in the 9th step, separation temperature is 60 DEG C~80 DEG C in separating still, and pressure is 1.9~2.8Mpa.
The beneficial effect of the method for the present invention includes at least one below,
1st, by seabuckthorn seeds by supercritical carbon dioxide extracting after, Seabuckthorm Seed Oil therein can be separated, separate
Seabuckthorm Seed Oil afterwards is organic solvent, is imported again in extraction kettle, is mixed with by broken seabuckthorn seeds, based on organic molten
The similar principle to mix of agent, when by supercritical carbon dioxide reextraction, can not face a part by the way that routine is super
The Seabuckthorm Seed Oil of boundary's extraction is taken out of, improves final Seabuckthorm Seed Oil yield, solves in existing Seabuckthorm Seed Oil extraction no matter use machine
Tool squeezing method, organic solvent method and conventional Supercritical carbon dioxide extraction method are long, inefficient there are extraction time, effectively into
Point loss is larger, and solvent-oil ratio is big, and the problem of easily cause the series of malpractice such as dissolvent residual in product.
2nd, since part A seabuckthorn seeds are used for conventional Supercritical carbon dioxide abstraction, its seabuckthorn seeds extract extracted can use
