“…These data underline that the liquid-vapor equilibrium of volatile compounds released from a liquid mixture, as is normal for EO, undergoes several parameters, including the solvent defined for different experiments, as demonstrated for the mixtures citronellal/geraniol and citronellal/citronellol at different vacuum pressures [52] or eugenol/ caryophyllene at reduced pressures [53].…”

The antimicrobial effect of eight essential oils’ vapors against pathogens and spoilage bacteria was assayed. Oreganum vulgare L. essential oil (OVO) showed a broad antibacterial effect, with Minimum Inhibitory Concentration (MIC) values ranging from 94 to 754 µg cm−3 air, depending on the bacterial species. Then, gaseous OVO was used for the treatment of stainless steel, polypropylene, and glass surfaces contaminated with four bacterial pathogens at 6–7 log cfu coupon−1. No viable cells were found after OVO treatment on all food-contact surfaces contaminated with all pathogens, with the exception of Sta. aureus DSM 799 on the glass surface. The antimicrobial activity of OVO after the addition of beef extract as a soiling agent reduced the Sta. aureus DSM 799 viable cell count by more than 5 log cfu coupon−1 on polypropylene and glass, while no viable cells were found in the case of stainless steel. HS-GC-MS analysis of the headspace of the boxes used for the antibacterial assay revealed 14 different volatile compounds with α-Pinene (62–63%), and p-Cymene (21%) as the main terpenes. In conclusion, gaseous OVO could be used for the microbial decontamination of food-contact surfaces, although its efficacy needs to be evaluated since it depends on several parameters such as target microorganisms, food-contact material, temperature, time of contact, and relative humidity.

“…In an endeavor to elevate the value of citronella oil, it becomes imperative to embark on a process of isolating its derivative compounds. This is achieved through a meticulous selection of techniques, including fractional distillation under vacuum condition, molecular distillation, or supercritical fluid extraction. The isolated pure components hold intrinsic worth, serving as fundamental raw materials for the formulation of various end products, spanning the realms of perfumes, soap fragrances, cosmetics, and pharmaceuticals…”

Liquid−liquid equilibrium data for ternary systems of geraniol + ethanol + water and citronellol + ethanol + water were obtained experimentally under atmospheric pressure and at temperatures of 303.15 and 323.15 K. The experiment was carried out using a jacketed equilibrium cell as a reference for citronella oil derivative component purification by the solvent extraction method. The experiment was held for 4 h stirring and 20 h settling before the organic and aqueous sample phases were taken to be analyzed. Gas chromatography was used to analyze the equilibrium samples of the organic and aqueous phase compositions. The experimental data were found to be thermodynamically consistent with the Othmer−Tobias and Bachman−Brown correlations. The data were well-correlated by NRTL and UNIQUAC models with rmsd ranging from 0.0086 to 0.0164 and following the type 1 classification by Treybal.
