Hence, the mechanism of the extraction is related to the physical properties of the sample while the energy source utilized for the EO extraction determines the velocity at which each phase appears. Different to our results, Haj Ammar et al.
(2013) tested a mathematical model based only in diffusion during extraction of EOs of myrtle (Myrtus communis L.), rosemary (Rosmarinus officinalis L.), or sour orange (Citrus aurantium L.),
observing that the calculated values by their model showed deviations with regards to the experimental ones during the first minutes of the process, these deviations are related to the omission of the first phase of the process (the equilibrium) that in Xavier et al. (2011) model, utilized in our work is taken into account.
