Abstract

On understanding the potential significance of the microwave-assisted extraction, studying the kinetics mechanisms and modeling of the extraction method is necessary. The aim of this study was to evaluate the suitable kinetic models for microwave hydrodistillation (MHD) of the essential oil from clove (Syzgium aromaticum) stem. MHD was performed of 100 g dried clove stem in 200 mL aquadest, heated at various power settings of 300, 450, 600 and 800 W. The extraction conducted for a total of 120 min with 10 min intervals. The experimental data (extract yields versus time) were fitted to four-two parameter empirical kinetic models. The total extract yields from clove stem oil exhibited a close fit to the hyperbolic model and Weibull's exponential. The result also suggested that the increase in microwave irradiation power significantly affected some of the parameter of MHD kinetic models.
