Microwave extraction of mint essential oil – Temperature calibration for the oven

Microwave assisted hydro-distillation of essential oils from fresh ginger root (Zingiber officinaleRoscoe)

“…However, the literature reports that the conventional methods can affect the final product quality, due to losses of some volatile compounds during the procedure, low extraction efficiency, and degradation of unsaturated compounds due to thermal effects or solvent used in the extraction [17,18].…”

Volatile Composition of Essential Oils from Different Aromatic Herbs Grown in Mediterranean Regions of Spain

“…Essential oils are extracted from various aromatic plants generally localized in temperate to warm countries, such as the Mediterranean countries [ 1 ]. Peppermint ( M. piperita L.) essential oils have been obtained by steam distillation in a Clevenger-type apparatus [ 5 ], while microwave extraction technique of mint essential oil was used by Costa et al [ 6 ]. Besides, Huopalahti and Linko [ 3 ] isolated aroma compounds of dill ( Anethum graveolens L.) by using solvent extraction technique.…”

Measuring dielectric properties for microwave-assisted extraction of essential oils using single-mode and multimode reactors

“…However, more recently, the application of innovative techniques such as microwaveassisted hydrodistillation (MAHD) and solvent free microwave extraction (SFME) has grown, along with other microwaveassisted techniques, including microwave steam distillation (MWSD) and the microwave-assisted hydrodiffusion and gravity (MWHG) method. [15][16][17][18][19] The main disadvantages associated with the conventional techniques are the degradation of some volatile compounds (due to long extraction times) and of unsaturated compounds through thermal or hydrolytic effects. Microwave dielectric heating is more effective and selective than conventional heating.…”
