S.Melo, Silvio Alexandre Beisl Vieira deKieckbusch, Theo Guenter2012-06-13T17:14:05Z2012-06-13T17:14:05Z20080104-6632http://www.repositorio.ufba.br/ri/handle/ri/6114v. 25, n. 3p. 543 - 552The paper reports on experimental data on the extraction of caffeine, coffee oil and chlorogenic acids from green coffee beans using pure supercritical CO2 and supercritical CO2 modified with ethanol (5% w/w) and isopropyl alcohol (5% w/w) at 50 and 60ºC and 15.2 24.8 e 35.2 MPa. In this study extraction kinetics were obtained for all assays i.e. samples were collected at several time intervals for each solvent and mixed solvent. When pure CO2 and CO2-ethanol mixed solvent were used, an increase in pressure resulted in an increase in the amount of oil extracted. When CO2 was modified with isopropyl alcohol, the amount of coffee oil extracted also increased with pressure. Caffeine extraction initially increased and subsequently decreased with pressure. Chlorogenic acids were only extracted when isopropyl alcohol was used as a co-solvent. An increase in extraction temperature resulted in a decrease of caffeine and oil extraction (retrograde condensation) when only CO2 was used as solvent. With the use of co-solvent this retrograde behavior was no longer observed and the increase in temperature resulted in the increase in the extracted amounts of caffeine, coffee oil and chlorogenic acids.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-06-13T17:14:05Z No. of bitstreams: 1 __www.scielo.br_pdf_bjce_v25n3_a12v25n3.pdf: 232111 bytes, checksum: 7b09e82902e1ef6b00f7088dc60e9a9b (MD5)Made available in DSpace on 2012-06-13T17:14:05Z (GMT).
