The supercritic al fluid is widely used to extract solutes from the interior of solid matr ices\, and also for counter-current extraction of a liquid stream.\n\nCork corresponds to the bark of the cork oak (Quercus Suber L.)\, a hundred pe rcent natural plant tissue\, that is composed\, in average\, by 14% extrac tives\; these extractives are mainly constituted by triterpenic compounds that have promising applications as bioactive compounds or precursors to d rug ingredients. Portugal is the world leader in the production\, processi ng\, and marketing of cork. The most important sector to the cork industry is the production of cork stoppers\; in the process of natural cork stopp ers production\, ca. 60% of initial raw material is rejected\; this reject ed material is milled to be used in other applications\, e.g. technical co rk stoppers\, agglomerated. This material was extracted using CO2 at super critical conditions\; the best performance for SFE was 19.7 g of extract / kg dry cork obtained at 210 bar and 41°C\; for SFE with co-solvent\, the yield increases almost 86%.\n\n\n\nYaidelin Manrique graduated in Chemica l Engineering at the University Simón Bolívar in Venezuela in 2007. She obtained her Integrated Master in Chemical Engineering in 2010 with the th esis “Modeling and Simulation of Water-Gas Shift Reactors: from Conventi onal Packed-Bed to Membrane Reactor” at the Faculty of Engineering of Un iversity of Porto (FEUP). In 2017\, she received her Ph.D. degree in Chemi cal and Biological Engineering from the FEUP with the Ph.D. thesis entitle d “Supercritical fluid extraction and fractionation of bioactive natural products from cork”. From that point forward\, she has been working as a post-doctoral researcher at LSRE-LCM participating in several research p rojects in the field of Product Engineering.\n\n\n\n \;\n\n[Host: Mari a Eugénia Macedo\, Associate Laboratory\, LSRE-LCM]\nImage credits: Yaide lin Manrique.
