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.

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.

The purpose of the present study is to investigate the changes in extraction yield, physicochemical properties, micronutrients content, oxidative stability and flavor quality of cold pressed peanut oil extracted from microwave (MW) treated seeds (0, 1, 2, 3, 4, 5 min, 700 W). The acid value and peroxide value of extracted oil from MW-treated peanuts were slightly increased but far below the limit in the Codex standard. Compared with the untreated sample, a significant (p < 0.05) increase in extraction yield (by 33.75%), free phytosterols content (by 32.83%), free tocopherols content (by 51.36%) and induction period (by 168.93%) of oil extracted from 5 min MW-treated peanut were observed. MW pretreatment formed pyrazines which contribute to improving the nutty and roasty flavor of oil. In conclusion, MW pretreatment is a feasible method to improve the oil extraction yield and obtain the cold pressed peanut oil with longer shelf life and better flavor.

Essential oil extraction of wild caraway and thyme was performed using a classical (HD) and microwave hydro-distillation (MWHD) and a laboratory supercritical fluid extraction (SFE) with a carbon dioxide as solvent. Our experiments demonstrated that the extraction yield of the essential oil performed in same conditions was influenced by the location of growth area; the maximum extraction yield of 10 ml 100 g-1 caraway was obtained from dried seeds collected from Csíkmadaras. This quantity far exceeded the yield of the Újtusnád samples. In the case of wild caraway (Carum carvi L.), the extraction method influenced thecomposition of the essential oil (carvone/limonene ratio), the highest limonene content being achieved by classical hydro-distillation. In the case of thyme, this effect was not detected, the thymol/carvacrol ratio was independent from the given extraction method. The obtained thyme essential oil possesses high antimicrobial activity demonstrated by agar diffusion test. The thyme extract provides a good protection against microorganisms collected on the surface of fresh vegetables following bacterial stains: Citrobacter portucalensis, Pseudomonas hunanensis, Pseudomonas baetica, Pseudomonas parafulva, Bacillus mojavensis and Enterobacter cloacae. Protective effect was also detected on the vegetable surface of by chitosan-based edible film coating during a 6-day-long storage period at a temperature of 4 °C. The caraway essential oil used as soft cheese seasoning with a direct, dilution-free method, proved to be unsuitable because the uneven distribution and confer a strong, unpleasant taste to the product in comparison with the ground wild caraway seed-dressed cheese.

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.

In the extraction of vegetable oils, the idea of using ethanol as a solvent, allowing solvent recycling without distillation, can be attested as early as 1948 (Beckel), yet it is now seldom envisaged. The development of organic farming and a growing demand for a more natural diet prompted us to revisit this approach, which takes advantage of the relatively low affinity of ethanol for lipids to produce pure crude oils and meal with higher protein content. This method is based on the change of oil solubility in ethanol with temperature. Rapeseed oil extraction was carried out by hot pressurized ethanol (subcritical extraction condition). Oil was then recovered by cooling the miscella and demixing of two phases, an oil-rich phase and a solvent-rich phase. This study, after verifying the kinetics of extraction, focused on the optimization of the demixing temperature based on the amount and quality of recovered oil. The results show that ethanol extraction followed by cold demixing of the miscella makes it possible to obtain a high quality oil, free of free fatty acids and phospholipids.

Smart sensors, self-configuration, operational flexibility, and automatic learning, among others, are technological attributes from industry 4.0 appliable to the essential oil extraction by the steam distillation process. These operations are recognized by their simplicity. Nevertheless, lack of automatic controls, process monitoring, and self-adjustment lead to uncontrolled extraction, poor yields, low quality of products. It occurs because of overexposure to high temperatures and overspending resources like energy and water. As far as capacity utilization is concerned, the optimized process is key to planning and managing the production activities.

Essential Oil Production

ABSTRACT The growing of Piper aduncum for essential oil extraction has increased, but there is a lack of basic information about its management and cultivation, which allows the productivity and quality of the oil, in order to attend the market demands. This study aimed to evaluate the relation between the production of essential oils from P. aduncum and soil water pressure heads (20 kPa, 40 kPa, 60 kPa, 100 kPa and non-irrigated). The assessment comprised the quantification of idioblasts and the production of essential oil extracted from leaves of cultivated plants. The variation in the soil water pressure head alters the amount of idioblasts in P. aduncum leaves, with impacts on the essential oil production. A soil water pressure head range of 20-60 kPa is sufficient for this species to express the highest amount of idioblasts and the highest level of essential oil production. The species adapts itself to different water availability conditions in the soil. Under stress conditions, due to water deficit or excess, the production of essential oil is reduced.
