Supercritical fluids for the treatment of bioactive components

Supercritical fluids are marked as green solvents able to substitute toxic organic solvents. Therefore, processes involving supercritical fluids are seen as, besides others, green chemical processes with a huge potential for the food and pharmaceutical industry. Research on supercritical fluids evolved with time, spreading the possibilities and opportunities. The following paper gives a brief overview of the process involving supercritical fluids. Supercritical extraction, supercritical drying and impregnation of aerogels and particles from gas saturated solution are explained through the research performed and published by our research group. The most significant achievements are thoroughly explained and compared with the results available in the literature. The most important conclusions are underlined, and future remarks are discussed.
