Pomelo peel-derived essential oils have been gaining popularity due to greater demand for stress relief therapy or hair care therapy. In this study, we first performed optimization of parameters in the pomelo essential oil extraction process on a pilot scale to gain better insights for application in larger scale production. Then extraction kinetics, activation energy, thermodynamics, and essential oil quality during the extraction process were investigated during the steam distillation process. Three experimental conditions including material mass, steam flow rate, and extraction time were taken into consideration in response surface methodology (RSM) optimization. The optimal conditions were found as follows: sample weight of 422 g for one distillation batch, steam flow rate of 2.16 mL/min and extraction time of 106 min with the coefficient of determination R2 of 0.9812. The nonlinear kinetics demonstrated the compatibility of the kinetic model with simultaneous washing and unhindered diffusion with a washing rate constant of 0.1515 min−1 and a diffusion rate constant of 0.0236 min−1. The activation energy of the washing and diffusion process was 167.43 kJ.mol−1 and 96.25 kJ.mol−1, respectively. The thermodynamic value obtained at the ΔG° value was −35.02 kJ.mol−1. The quality of pomelo peel essential oil obtained by steam distillation was characterized by its high limonene content (96.996%), determined by GC-MS.

The main objective of this study is to improve the mathematical modelling of Cymbopogon winterianus essential oil extraction by steam distillation proposed by Cassel and Vargas by minimum 5% error reduction. Two process variable of steam distillation which are extraction time and raw material state (dry or natural) has been optimized by using factorial experimental planning to obtain high yields of citronella essential oil from twig and leaves of lemongrass species Cymbopogon winterianus (C.winterianus). The optimal condition for maximum yield (0.942%) were found to be an extraction time, 4 hr, state, natural plant. The study of Cassel and Vargas was subsequently continued with five proposed kinetics model of the extraction process. The modelling of the extraction process is optimized by using one adjustable parameter of the model and the adequacy of the fit of the models to the experimental data are analyzed by using three statistical criteria that are correlation coefficient (r) ,the root mean square error (RMSE) and the mean relative deviation modulus (E). The result has shown that the mathematical model developed by Ana based on mass transfer fundamentals is the optimum mathematical model for the extraction of Cymbopogon winterianus essential oil by steam distillation.

Objective: In this study, the extraction of oil from Pistacia terebinthus L’s seeds grown in Elazig-TURKEY and called menengic in domestic region was investigated. Crude oil content of the seeds obtained from this region was determined as approximately 47% (w/w). Methods: Effects of the parameters such as extraction time, temperature, seeds/solvent ratio (dosage), the particle size of seeds and type of solvent were examined on the oil extraction yield. In this context, it has concluded that up to a certain point, the extraction time has increased the yield of oil extracted. But the extraction temperature showed activity as depending on the solvent type. Results: As expected, it has been observed that the yield of oil has decreased depending on the increase in particle size and dosage as well. The mathematical model obtained by solving Fick's second law under the appropriate boundary and initial conditions were used to calculate diffusion coefficients for the extraction process. Diffusion coefficients for the seeds with a particle size of 0.55 mm were found to be between 1.15x10-11 and 1.86x10-11 m2s-1. To compare the extraction yield of Pistacia terebinthus L’s seeds with that of sunflower at the same conditions, the diffusion coefficients of sunflower seeds were calculated in the range of 9.11x10-12 and 1.13x10-11 m2s-1. Conclusion: These figures show that the diffusion coefficients calculated for both oily seeds are nearly equivalent to each other. The fatty acid composition of extracted oil from Pistacia terebinthus L’s seeds was determined by GC-FID. The GC-FID results showed that oleic, linoleic (ω-6) and palmitic acid were main fatty acids in the oil obtained from menengic seeds.
