/ 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
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 th
