RIOS, LUIS et al. EXTRACTION AND CHARACTERIZATION OF CARDAMOM OIL (Elettaria cardamomum). Dyna rev.fac.nac.minas [online]. 2007, vol.74, n.151, pp.47-52. ISSN 0012-7353.

Cardamom (Elettaria cardamomum) is an agricultural product with high industrial and commercial potential. Results on the extraction of essential oil of cardamom are reported. Three extraction techniques were studied: steam distillation, hydrodistillation and extraction with solvents. The components of the oil were identified and quantified by gas chromatography with mass and TCD detectors, respectively. The obtained yields were 4,7% by steam distillation, 3.7% by hydrodistillation, and 6,5% by extraction with solvents. The main identified compounds were: cineol, terpinyl acetate, linalol and ?-pinene. Results show that there is not water in the oil sample, and the maximum concentration of residual solvent in the oil is 72,4 p.p.m. The obtained results allow to determine the main operational variables to perform the basic desing of a pilot plant for extraction of the oil.
