/ PRODUCTION METHOD OF EXTRACT PARTICLES USING DRYING/PURIFICATION PROCESS OF SUPERCRITICAL FLUID THE EXTRACT PARTICLES PRODUCED BY THE PROCESS AND COSMETIC COMPOSITION CONTAINING THE SAME

摘要

More particularly, the present invention relates to a method for producing fine particles of extract with high purity active ingredient using supercritical fluid drying / refining process, (2) extracting a coloring matter-containing effective ingredient from the powder obtained in the step (1) using an extraction solvent; (3) spraying the dye-containing effective ingredient extracted in the step (2) into a drier in which a supercritical fluid or a supercritical fluid and a co-solvent flow continuously; And (4) collecting fine particles of an extract powder in the form of a solid powder in a recovery section located at the lower end of the dryer, wherein the supercritical fluid is supercritical carbon dioxide, and the active ingredient is a flavonoid- Wherein the extraction solvent is selected from the group consisting of ethanol, methanol, acetone, and dimethyl sulfoxide, or a mixture thereof, or a mixture of any one thereof or a mixture thereof in an amount of 0.01 to 50% by volume Water, or a mixture containing water is used. In the step (3), any one of ethanol, methanol, acetone, dimethylsulfoxide, dichloromethane or a mixture thereof is used as the co-solvent, , Grapes, plums, blackberries, assyberries, aronia, blueberries, cranberries, kale, strawberries, raspberries, sugar beets, cherries, broccoli, tomatoes, o The composition is characterized in that it is composed of one or a mixture of stevia, pomegranate, chlorella, red ginseng, alfalfa, aloe, chaga mushroom, onions and green plants. The present invention also relates to fine particle extracts containing high purity active ingredient and a cosmetic composition containing the same, which are produced by the above-described method for producing extract fine particles containing a high purity active ingredient by using a supercritical fluid drying / refining step. According to the process for producing fine particle extracts containing high purity active ingredient as proposed in the present invention, and the fine particles of extract with high purity active ingredient and the cosmetic composition containing the same, the supercritical fluid and cosolvent rapidly penetrate into the droplet of the extraction solution, It is possible to produce a large amount of extract fine particles while inducing drying / purification. Further, according to the present invention, in order to overcome the disadvantage of supercritical carbon dioxide which can hardly dry the solution containing water, it is possible to obtain the solid extract from the extract solution containing a large amount of water by improving the affinity with water In addition, it is possible to simplify complicated multi-step processes such as separation-concentration-drying proceeding after extraction, and to produce an extract containing a large amount of an effective ingredient from natural products containing a large amount of natural antioxidants. In addition, the present invention extracts colorless and lipophilic components such as chlorophyll, which are easily discolored due to light, at the same time as drying, thereby obtaining the unpigmented colorless extract microparticles maximizing the purity of the active ingredient, and making them usable as cosmetic raw materials . The present invention also relates to a cosmetic composition containing an extract of a large amount of an active ingredient as a raw material for cosmetic, in order to eliminate the risk that the residual organic solvent is exposed to the skin, So that it is possible to obtain an extract of a particulate form safe to the human body.
