REYES-NAJAR, Armando et al. OBTENCIÓN DE EXTRACTOS DE JENGIBRE (Zingiber officinale) EMPLEANDO CO₂ SUPERCRÍTICO. []. , 35, 136, pp.381-385. ISSN 0370-3908.

^les^aMediante extracción con fluidos supercríticos-EFS se obtuvieron extractos de rizomas de jengibre (Zingiber officinale), con CO₂ a diferentes condiciones de presión y temperatura. Adicionalmente, mediante extracción soxhlet se obtuvieron extractos lipofílicos. Los rendimientos de extracción fueron determinados y los extractos obtenidos se analizaron mediante cromatografía de gases acoplada a espectrometría de masas (CG-EM). La EFS permitió obtener extractos libres de solvente, alcanzando un rendimiento de 1.51% a 17.9 MPa y 40 ºC. por CG-EM se lograron identificar más de treinta componentes presentes en los extractos, algunos de los cuales le imparten el aroma característico al jengibre y poseen importantes tipos de actividad biológica.^len^aExtracts from ginger rhizomes (Zingiber officinale) were obtained by supercritical fluid extraction- SFE, with CO₂ at different conditions of temperature and pressure. Additionally, lipophilic extracts were obtained by soxhlet extraction. The extracts were analyzed by gas chromatography-mass spectrometry (GC-MS) and there were determined the respective extraction yields. With SFE was possible to obtain solvent free extracts, they were enriched with aroma impact compounds and with important biological activity compounds, reaching an extract yield of 1.51% to 17.9 MPa and 40 ºC. Over thirty components present in the extracts were identified by GC-MS.
