Description
Technical field
The invention belongs to extracting substances technical fields, and in particular to fatty acid object in a kind of supercritical fluid extraction sesame
The technique of matter.
Technical background
The common extracting method of natural products has solvent extraction method, ultrasonic extraction, microwave loss mechanisms and enzyme to mention at present
It follows the example of.Although extracting modes such as extraction methods, recovery rate is higher, it has inevitable defect, that is, has solvent residual
It stays, for thermal sensitivity food, heating can cause certain unsaturated fatty acids that the chemicals such as the variation, such as DHA, ARA of matter occur
The change of matter generation matter.And natural extract is mainly used for the fields such as food, cosmetics.With the improvement of living standards, people
It is higher and higher to the nutritional quality of the products such as food, cosmetics, sensible quality, freshness requirement, it is obtained by extraction
Natural products be extremely difficult to require, so the abstraction technique of low temperature, organic solvent-free is gradually valued by people.Currently,
Low temperature, no solvent residue high-new extraction and separation technology mainly have supercritical extract fluid technique, aqueous enzymatic method technology, pulverize
Technology, molecularly distilled etc..
Sesame is one of China's major oil crops, is the annual herb plant of Pedaliaceae, sesame category.Contain in sesame
Protein, grease, carbohydrate, minerals, vitamin and lignin.The oil that main component in sesame is 45%~63%
Rouge, 19~31% protein, 20~25% carbohydrate.Sesamin also known as sesamin, sesamin, sesamin, it is a kind of
Fat-soluble phenol organic matter.With going deep into for research work, Japanese, which has found that sesamin has, reduces cholesterol, liver protection shield
Liver eliminates interior free yl, promotes a variety of physiological active functions such as alcohol metabolism.
The extracting process of common sesame oil: solvent extraction method, ultrasonic extraction, microwave loss mechanisms and enzyme extraction method,
Supercritical fluid extraction etc..In common extracting process, only solvent extraction method often uses the extraction of natural products to produce, this
Extracting process not only has dissolvent residual, and production cost is higher.
Supercritical CO2The principle of extraction separation process is to utilize supercritical CO2Have to certain special natural products special molten
Solution effect, utilizes supercritical CO2Solvability and its density relationship, i.e., using pressure and temperature to supercritical CO2Dissolve energy
The influence of power and carry out.In supercritical CO2It is in contact with the substance to be separated, makes it selectively polarity size, boiling point
The height ingredient different with molecular size range is extracted in turn.
At present it is believed that supercritical CO2It is mainly following several to extract advantage: 1) critical-temperature and critical pressure (Tc
=31.1 DEG C, Pc=7.38MPa), operating condition is mild, destroys to effective component few；2)CO2It can regard as and nothing as water phase
Malicious, cheap organic solvent；3)CO2It is stable in use, nontoxic, do not burn, be safe, is free from environmental pollution, and can avoid
The oxidation of product；4)CO2Nitrate and harmful heavy metal, and the residual without hazardous solvent are free of in extract；5) exist
Supercritical CO2When extraction, the substance being extracted can be precipitated by reduction pressure, or raising temperature, it is not necessary to by extracting repeatedly
Operation.
However in the prior art, there are no use supercritical CO2The technique for extracting fatty acid substance in sesame.
Summary of the invention
