The development of new supercritical fluid processing technology as applied to nutraceuticals and natural products is no longer confined to using just supercritical fluid extraction (SFE). In this presentation areas relevant in our group will be emphasized: (1) extracting nutraceuticals from natural sources, such as spices, natural antioxidants and herbal components by supercritical fluid. (2) Analyzing natural products constituents via supercritical fluid with favorable and comparable efficiencies will be described in the second part. (3) Reducing particle size with a narrow size distribution, application of the various particle formation processes conducted in critical fluid, such as: SAS, RESS, PGSS, and GAS. The third part will highlight the process using critical fluid to produce some nutraceutical and natural products nanoparticles we are interested in. (4) the last part will focus on the in-line encapsulation of certain natural active components in polymer matrix via supercritical fluid to modify their release profile.
