Steam explosion was proposed as a pretreatment method to accelerate the hydrodistillation (SE-HD) of kaffir lime leaves. This research aimed to compare SE-HD and conventional hydrodistillation (HD) in terms of extraction yield, extraction time, chemical composition, and essential oil quality. The extraction of kaffir lime oil with SE-HD was superior to HD with regard to extraction time (35 min. vs 120 min.) and extraction yield (1.386% vs 1.182%). The chemical composition and the quality of the extracted essential oil from both methods were quite similar, indicating the absence of adverse influence from the application of steam explosion as pretreatment. Therefore, SE-HD was a fast and an energy-saving method for extracting essential oil from kaffir lime leaves.

Gaharu oleoresin is a mixture of wood resin and essential oil substances that naturally accumulates in the gaharu plants species. The aim of this study was to determine the appropriate solvent types and the contents of oleoresin and oil as well as the chemical compounds present in the gaharu extracts. Gaharu oleoresin can be extracted from gaharu powder using polar solvents and the essential oil can be separated using non-polar solvents. The extraction was done by Soxhlet method using methanol and ethanol for oleoresin extraction, and n-hexane and toluene for oil extraction from which the most appropriate solvents, extraction yields and the extracts quality were determined. The percentage of oleoresin extraction yield was found highest in methanol (6.97 %) followed by ethanol (6.85 % w/w). Meanwhile, the gaharu oil was found higher in toluene extract (1.06 %) compared to n-hexane (0.38 % w/w). The GC-MS results showed the extracts from ethanol and n-hexane solvents are the best quality due to the present of key compounds of 4-phenyl-2-butanone, β-guaiene, agarospirol, α–bisabolene, alloaromadendrene oxide, γ-Gurjunen and aromadenderene oxide. Different chemical component in gaharu oil determines the characteristic or quality of the gaharu. Meanwhile, the sesquiterpene compounds in gaharu produce its specialty aroma characteristics. Therefore, ethanol and n-hexane solvents are suitable to be used for oleoresin and oil extraction beside less expensive and more environmental-friendly.

AbstractThis study aimed to investigate the effect of low-pressure dielectric barrier discharge (DBD) plasma on microwave-assisted hydrodistillation of lemon peel oil extraction. Microwave pre-treated lemon peel powder was exposed to plasma treatment (1.0, 1.5, 2.0, and 2.5 kV) for 10 min. The treated lemon peel powders were subjected to hydrodistillation to extract the essential oil and the extraction yields were calculated. The extracted oil was analyzed for chemical composition with gas chromatography-mass spectrometry (GC-MS). Effect of plasma on the surface morphology of the lemon peel was observed in a scanning electron microscope (SEM) which revealed the formation of fissures and cracks owing to the higher extraction yield. Plasma treatment at 2.5 kV was observed higher extraction yield than conventional hydrodistillation (149.34 % rise) and the chemical composition of plasma treated sample essential oil remains significantly unchanged. Thus, DBD plasma could be a promising technique to enhance the lemon peel essential oil extraction.

Indonesia is one of the largest spice-producing regions such as the Java Cardamom (Amomum compactum). The cardamom can be converted into derivative products in the form of cardamom essential oil. In this work, we attempted to extract the essential oil from the cardamom by comparing two methods of extraction which are the steam distillation and the simple distillation. The optimization factors considered on the extraction yield were solvent (ethyl acetate and n-hexane) and extraction time (3-6 h). The extraction yield obtained by both methods in ethyl acetate solvents was almost equal to that obtained in n-hexane. Also, the result obtained revealed that the extraction yield increased with time. The optimum essential oil yield was obtained by the simple distillation method in 6 hours duration time using n-hexane solvent giving the yield of 6.3 %. Gas Chromatography-Mass Spectrometry (GC-MS) was used to identify the chemical composition of the extracted oil. The results showed that the chemical composition of the essential oils is different in each extraction time. The main compounds in all oil samples were eucalyptol and camphene among four other constituents. The concentration of eucalyptol reached an optimum (90.89 - 93.74 %) at 4 – 5 h of distillation times, while the concentration of camphene reached an optimum (52.98 %) at 6 h. The purity of the essential oil was confirmed by Fourier Transform Infra-Red (FTIR). Moreover, this research will help to utilize the cardamom due to its main compounds that act as herbal medicine.

The extraction of essential oils is generally carried out by two main techniques: azeotropic distillation (hydrodistillation, hydrodiffusion, and steam distillation) and extraction with solvents. However, these traditional methods are a bit expensive, especially since they are extremely energy and solvent consuming. This work consists in studying two methods of extraction of the essential oils of Rosmarinus officinalis L.: microwave assisted hydrodistillation (MAH) and Clevenger hydrodistillation (CH). Several parameters have been studied: the extraction time, the yield, and the chemical composition of the essential oils as well as the efficiency and cost of each procedure. The results obtained revealed that microwave-assisted hydrodistillation makes it possible to minimize the extraction time of the essential oils in comparison with conventional hydrodistillation. Thus, the same yield of essential oils is obtained for 20 minutes only with MAH while it takes 180 minutes with CH. In addition, the quality of the essential oil is improved thanks to a 1.14% increase in oxygenates. In conclusion, the MAH method offers significant advantages over conventional hydrodistillation and can therefore replace it on a pilot and industrial scale.

In this study, different oil extraction processes, such as extrusion pretreatment, ultrasound-ethanol assisted demulsification and traditional hexane extraction of oil, were employed to extract oil from soybean in order to compare their different effects on oil quality, fatty acid distribution and VE content of oil. The result shows that the quality of oil from extrusion pretreatment aqueous enzyme extraction (EAEP) of oil and ultrasound-ethanol assisted demulsification aqueous enzyme extraction of oil were same. The raw oil quality from the above two processes was better than the hexane extraction of oil. The fatty acid contents of oil were similar in different oil extraction processes. The VE content of oil from ultrasound-ethanol assisted demulsification process was decreased, while the extrusion pretreatment aqueous enzyme extraction of oil had no influence on VE concentration.

Pomelo Peel

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 effect of different hydrodistillation pretreatments, namely, reflux extraction, reflux extraction with the addition of cell wall-degrading enzymes, and ultrasound, on the yield and chemical composition of essential oils of sage, bay laurel, and rosemary was examined. All pretreatments improved essential oil yield compared to no-pretreatment control (40–64% yield increase), while the oil quality remained mostly unchanged (as shown by statistical analysis of GC-MS results). However, enzyme-assisted reflux extraction pretreatment did not significantly outperform reflux extraction (no-enzyme control), suggesting that the observed yield increase was mostly a consequence of reflux extraction and enzymatic activity had only a minute effect. Thus, we show that ultrasound and reflux extraction pretreatments are beneficial in the production of essential oils of selected Mediterranean plants, but the application of enzymes has to be carefully re-evaluated.
