Oil Performance

Vietnam is the world's leading country in growing and producing pepper trees. In this study, we attempted the optimization of white pepper essential oil extraction. The obtained oil was then subject to determination of constituent composition via GC-MS method. The essential oil performance achieved 3.6% by hydro-distillation process with optimal conditions (25 grams of fresh pepper, size 18, 120 minutes extraction, 130°C). A total of 23 volatile constituents were identified from the white pepper essential oil, with the major components being 27.4% of Limonene, 3-Carene 22,928%, Sabinene 17,622%, β-pinene 10.068%, α-Pinene 5.426%.

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.

Orange Essential Oil

Abstract Background: A huge amount of citrus by-products are being wasted every year; these by-products can be used in the extraction of essential oils which can be used in different fields. Many methods have been used in the extraction of orange essential oil (E.O). This study focuses on the extraction of essential oil from orange by-product, using a newly developed extraction technique. This technique is a prototype combining a conventional method, namely, the hydrodistillation with the ultrasound-assisted extraction. Indeed, the traditional extraction methods of essential oils are time-consuming and expensive, moreover many organic compounds may decompose at high retained temperatures.Methods: a combination of traditional method with sonication improves efficiency and quality of the extraction, since ultrasonic extraction with precise and controlled operating parameters leads to higher extraction yields with minimum energy consumption. Therefore, the orange essential oil obtained using the prototype was compared to two commercial oils (CO1 and CO2) to create a valid comparison. Quality and safety tests have been performed, as well as bacterial load, antibacterial activities using the disc diffusion method, minimum inhibitory concentration (MIC), and prevention of bacterial biofilm formation.Results: As a result of extraction, the prototype method has shorten the extraction time, gave a higher quantity, and improved the extraction of essential oil from citrus peels without affecting oil composition when comparing it to hydrodistillation method. Conclusion: Orange E.O can be used as natural antibacterial agents to minimize bacterial growth, and inhibit biofilm formation by Staphylococcus aureus, Listeria monocytogenes and E.coli.

Fruit Oil

Most often during the processing of lime fruits for essential oil extraction, rotten fruits are used along with ripe ones. In this study, we examine the volatile constituents of the essential oils from both ripe and rotten lime fruits (Citrus aurantifolia Swingle) from Nigeria. The oils were isolated by hydrodistillation and analyzed using GC-MS. The ripe and rotten lime oils contained 55 and 49 components, respectively. Both oils were rich in limonene (21.0%, ripe lime; 21.3% rotten lime), α-terpineol (11.7%, ripe; 14.1%, rotten), terpinene (8.3%, ripe; 8.9% rotten lime), α–terpinolene (2.5%, ripe; 8.5%, rotten) and ( E)-α-farnesene (6.3% ripe lime; 4.8% rotten lime). The other major components, α-pinene (11.1%), and linalool (5.5%) were identified in ripe lime oil only. Limonene and citral, which are believed to be the two major citrus odour contributors, were present in both ripe and rotten lime oils. Aldehydes like decanal and the farnesenes, which are also important in citrus flavor, were represented in both lime oils. Some notable components of ripe lime fruit oil, like trans-β-ocimene, linalool, myrcenol, dodecanal, trans-β–bergamotene and trans-γ–bisabolene, were absent in the rotten fruit oil. It could be suggested that some compounds like cis-ocimene, trans-linalool oxide, p-mentha-3-en-1-ol, mentha-1,4,8-triene, citronellal, trans- β–bergamotene and α–copaene, which were not identified in the ripe fruit oil, were introduced into the lime oil by the incorporation of rotten fruits in the distilled samples.
