Terpenes in essential oils are easily oxidized and can cause a decrease in the flavor in foods. Removal of Terpenes is commonly practiced in perfume industry to yield higher quality oils. Natural spearmint oilcontains l-limonene that is quite unlike d-limonene, the aroma is not reminiscent of citrus but of a light, clean Terpene hydrocarbon fragrance. Conventionally, Terpenes are removed using vacuum distillation. However, it is difficult to monitor the fractionation process in real-time during this process. We used SFC with a PDA detector and an FTIR spectrometer as a dual monitoring system to enable selective monitoring of the target compound Carvone in real time during elution and fractionation. The PDA provides broad information on the separation, but cannot differentiate between limonene and Carvone.
