Production of extracts from vegetal matrices with biological properties has attracted great interest of food, cosmetic, and pharmaceutical industries. Within this demand, the extraction process using supercritical carbon dioxide (SFE-CO2) has been shown to be a technically and economically feasible technology for the extraction of several substances. It has some advantages over conventional techniques, both in terms of yield and quality of the extract. Thus, the objective of this work is the application of SFE-CO2 extraction in the extraction of the turmeric volatile oil. This oil is rich in ar-turmerone, compound that has been reported in the literature by presenting some bioactive properties, such as, anti-inflammatory, antimicrobial, antioxidant and anticarcinogenic activity. Moreover, this raw material will be used for the following studies in the SFE-CO2 context: study of the influence of different bed geometries and scale-up on the SFE-CO2 process; determination of the temperature profile within in extractors with different geometries during the extraction kinetics and study of the influence of temperature gradient on the process efficiency; study of the SFE-CO2 process operating in continuous mode in laboratory and pilot scales. Such studies are important for the development and industrial application of the SFE-CO2 process. The compounds present in the extract of the volatile oil will be identified by Gas Chromatography-Mass Spectrometry (GC-MS) and quantified by Gas Chromatography with Flame Ionization Detection (GC-FID). Finally, the cost of manufacturing of extracts will be estimated using the simulator SuperPro Designer® 8.5. (AU)
