Rice bran oil was extracted using hexane, as well as subcritical butane and propane. The quality of rice bran oils obtained using these three solvents was comparatively studied. The results showed that subcritical fluid extraction oil showed higher concentrations of health-conducive components (such as vitamin E, oryzanol, and phytosterol) compared with hexane-extracted oil. Extraction solvent ...

Oil from brebra (Millettia ferruginea) is the potential raw material for biodiesel production. The refining of crude oil requires a series of purification steps to produce quality biodiesel. The objective of the study was to produce refined oil from brebra seed for biodiesel production. Crude oil extraction was carried out using mechanical press and solvent extraction methods. Impurities of the...

The supercritical fluid extraction (SFE) of Lepidium apetalum seed oil and its anti-oxidant activity were studied. The SFE process was optimized using response surface methodology (RSM) with a central composite design (CCD). Independent variables, namely operating pressure, temperature, time and flow rate were evaluated. The maximum extraction of Lepidium apetalum seed oil by SFE-CO₂ (about 36....

Waste oil industry has a great potential use, as 77% oil yield are an untapped waste that still has a high economic value as a base for the oleochemical industry, one of which is β-carotene. The study was conducted to optimize the extraction of carotenoids from Crude Palm Oil (CPO) and Palm Oil Mill Effluent waste (POME) conducted by column chromatography and extraction method with a single enz...

Tiger nut oil is a novel oil that requires more research data on its characteristics. In this study, the oil was extracted using both enzyme-aided pressing (EAP) and aqueous enzymatic extraction (AEE) methods. Using enzymes as a pre-treatment prior to mechanical pressing increased the concentration of some phenolic acids and tocopherols present in extracted oils compared to controls. High press...

Oil extraction may cause extensive environmental impact that can affect health of populations living in surrounding areas. Large populations are potentially exposed to oil extraction related contamination through residence in areas where oil extraction is conducted, especially in low and middle income countries (LMICs). Health effects among people residentially exposed to upstream oil industry ...

Seeds were collected from locally and naturally grown Chinese tallow trees (CTT) and characterized for general physical and chemical properties and fatty acid composition of the lipids. The effects of four different solvents (petroleum ether, hexane, diethyl ether, and 95 % ethanol) and two extraction methods (supercritical carbon dioxide (SC-CO2) and conventional Soxhlet) on the properties of ...

Microwave-assisted extraction of volatile oils (MAE) potentially offers a more efficient and bio-sustainable method than conventional extraction by Clevenger apparatus (CE). This study aimed to optimise the MAE of the volatile oil from Pterodon emarginatus fruits and characterise the volatile compounds. A 2³ full-factorial central composite design and response surface methodology were used to e...

The genus Haplophyllum, which belongs to the Rutaceae family, includes 18 species in Iran. In this study, after collecting plant material, botanical identification and suitable drying, the essential oils from aerial parts of Haplophyllum robustum Bge. were extracted by three different isolation techniques, conventional hydrodistillation (HD), microwave-assisted hydrodistillati...
