In the palm oil refining processes, the free fatty acid content is reduced to an acceptable level by using steam-stripping that causes, also, the loss of nutraceuticals such as tocopherols and carotenoids. An alternative method, such as solvent extraction, to separate free fatty acids, especially palmitic acid as the major free fatty acid present in palm oil, will conserves not only the important nutraceuticals but, also, conserves energy because a steam requirement is eliminated. The ...

This research considers the application of Natural Deep Eutectic Solvents (NADES) as green solvents for the extraction of bioactive compounds, mainly ?-mangostin, from the pericarp of mangosteen (Garcinia mangostana L.). Extractions were carried out using NADES consisting of choline chloride, a quarternary ammonium salt, and four hydrogen bond donors: 1,2-propanediol, citric acid, glycerol, and glucose. The highest ?-mangostin extraction yield of 2.6 % (w/w) in dried pericarp was obtained using a mixture of choline chloride ...
