Abstract

A supercritical fluid extraction (SFE) process was optimized to obtain high quality mint oil. The effect of oven and freeze drying techniques on the quality of mint oil was investigated. The flavor principles in the SFE extract were compared with those obtained by a conventional steam distillation method. Then highest extraction yield was obtained at SFE conditions (50°C and 350 bar), however, high quality oil was obtained at 30°C and 150 bar. The compositional quality of SFE extract was found to be superior as compared to that of a steam distillation process. The extraction yield and compositional quality of oil from mint samples obtained from different regions of UAE and other countries were reported.
