Course A :
Recrystalization and Encapsulation of Bioactive Compounds
in Supercritical Medium

Prof. Dr. José Vladimir de Oliveira
Chemical and Food Engineering Department, Federal University of Santa Catarina, Florianópolis, SC, Brazil

Time: Monday, April 1st, 9:00 – 11:00
Who Should Attend: Engineers, chemists, pharmacists, professional health sciences, biologists.
Course language: English

Course description: This short course comprises a brief review of the state of the art regarding encapsulation techniques (SAS, SEDS, GAS, ASES, PCA, etc.) with focus on the solution enhanced dispersion by supercritical fluids (SEDS) method. Especial attention is devoted to recrystallization and co-precipitation of solutes in supercritical carbon dioxide, investigating the effects of processing parameters (temperature, flow rate of solution and antisolvent, drying rate, initial concentration of the solid in solution, diameter and length of the capillary expansion tube and pressure gradient between the organic solution feed and the precipitation chamber) on the recrystallization and encapsulation of some solutes (theophylline, beta-carotene, astaxanthin, grape seed oil, etc.)

Course B :
Modeling of Solid Substrates Extraction

Prof. Dr. José Manuel del Valle
Chemical Engineering Department, Pontificia Universidad Católica de Chile, Santiago de Chile, Chile.

Time: Monday, April 1st, 11:00 am – 1:00 pm
Who Should Attend: Engineers and chemists
Course language: Spanish (slides in English)

Course topics: Differential mass balances, estimation of physical properties, film coefficients for external mass transfer, axial dispersion coefficients, pretreatments, microstructure parameter definition, effective diffusivity, solute partition equilibrium between substrates pretreated and carbon dioxide.

Course C :
Current and Potential Application of Supercritical Fluid Extraction in our diversity

Prof. Eng. M.Sc. Luis Ignacio Rodríguez Varela
Chemical Engineering Department, Universidad Nacional de Colombia, Bogotá, Colombia.

Time: Monday, April 1st, 1:00 pm – 3:00 pm
Who Should Attend: Engineers, chemists, pharmacists, professional health sciences, professional earth sciences.
Course language: Spanish

Course description : This short course is about the possibilities and potential of applying supercritical fluid extraction for the extraction of active ingredients, natural colors, essential oils, antioxidants and vitamins with application in food, beverages, cosmetics and pharmaceuticals. The course will show some applications that have been made and the products that have been obtained. Supercritical technology has a high potential for adding value to our biodiversity by developing useful products for the mentioned areas.
