A pilot plant was designed and used to extract cumin seeds (Cuminum cyminum
L.) using supercritical carbon dioxide at 40 degrees C and 100 bar. The ex
tracts obtained were compared with cumin essential oil obtained by conventi
onal steam distillation, using GC-MS. The analyses show that valuable compo
nents are extracted by the supercritical procedure, which would otherwise b
e thermally degraded by conventional steam distillation. Copyright (C) 1999
