“…The asymptotic profile obtained was characteristic of most SCCO 2 extraction reported in other microalgal studies (Cheung, 1999). The model correlated well with the experimental data for lipid evolution (compare 'Theoretical lipid yield' with 'Experimental lipid yield', r 2 60 C ¼ 0:93, r 2 80 C ¼ 0:92) and was consistent with the expected diffusion-driven nature of the SCCO 2 process, where the extraction rate was directly proportional to the amount of unextracted intracellular lipids (Ozkal et al, 2005).…”

“…An assumption was made that saturation of solute into the CO 2 was attained at these low velocities. The velocity employed in our study was comparable to the velocities reported in the literature dealing with dynamic method of solubility measurement (Danielski et al 2007;Ozkal et al 2005). Extraction curves are represented by the amount of CO 2 used for extraction and amount of caffeine extracted (Figs.…”

“…1 & 2). A second order polynomial equation was obtained fitting to the experimental data, and a straight line was drawn through the linear portion of the curve in order to find the initial slope (Danielski et al 2007;Ozkal et al 2005). Solubility values determined as weight fractions (kg caffeine/kg CO 2 ) were converted to mole fractions as required in the modeling equations.…”

“…El problema con muchos de los fluidos que aparecen en la Tabla 1, en comparación con el CO 2 es que hay ciertas dificultades en obtener solventes puros del fluido (Rozzi y Singh, 2002;Wark, 1985). Las ventajas de los fluidos supercríticos son: (Bruner, 2005;Hurtado, 2002;Sánchez et al, 2005;Tonthubthimthong et al, 2001;Zkal et al, 2005 1. Poseen alto coeficiente de difusión y viscosidad más baja que los líquidos; 2.…”

* autor a quien debe ser dirigida la correspondencia ResumenEsta presenta una revisión sobre el uso del dióxido de carbono supercrítico como solvente para la extracción de compuestos bioactivos presentes en vegetales de actual y potencial uso, en procesos de la agroindustria. Se hace una descripción de la extracción con soxhlet, la cual se usa para evaluar el rendimiento en extracto y en tiempo de extracción, de los métodos tradicionales y recientes de extracción. Se describe la extracción con fluidos supercríticos, se muestran condiciones de operación y se nombran algunos principios bioactivos extraídos de diferentes materias primas vegetales, reportados en la literatura internacional. Para una mejor descripción de las aplicaciones de los fluidos supercríticos en la agroindustria, estas se clasifican en cinco grupos bien diferenciados. Esto permite formarse una idea global clara sobre las posibilidades que ofrecen los fluidos supercríticos para mejorar la competitividad de la agroindustria. Palabras claves: dióxido de carbono, extracción supercrítica, extracción soxhlet, agroindustria Applications of Supercritical Fluids in the Agroindustry AbstractA review on the use of supercritical carbon dioxide as a solvent for the bioactive compounds extraction present in vegetables of current and potential use in agroindustrial processes is presented. A description of the extraction with soxhlet, which is used to evaluate the yield in extract and in extraction time of traditional and modern extraction methods is done. Extraction with supercritical fluids is described, operation conditions are showed and bioactive principles extracted from different vegetables raw material reported in the international literature are described. To better described the applications of supercritical fluids in the agroindustry, these are classified in five well defined groups. This allows to get a clear global idea about the possibilities offered by the supercritical fluids to improve the competitiveness of the agroindustry.
