Edible oil refining is a set of processes or treatments necessary to turn vegetable raw oil into edible oil.. Raw vegetable oil, obtained from seeds by pressing, solvent extraction, contains free fatty acids and other components such as phospholipids, waxes, peroxides, aldehydes, and ketones, which contribute to undesirable flavor, odor, and appearance; [1] for these reasons, all the oil has ...
Palm oil block showing the lighter color that results from boiling. Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of oil palms. [1] The oil is used in food manufacturing, in beauty products, and as biofuel. Palm oil accounted for about 36% of global oils produced from oil crops in 2014. [2]
Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.
Breaking it down to its simplest formulation, the process that oilseed presses carry out appears is quite simple. Oilseed presses essentially extrude or ‘press’ vegetable oil from oil-bearing seeds, which include soybean, sunflower, peanut, safflower, canola, sesame, niger, castor bean, linseed, mustard, coconut, olive, and oil palm.

Palm oil formed the basis of soap products, such as Lever Brothers' (now Unilever) "Sunlight", and B. J. Johnson Company's (now Colgate-Palmolive) "Palmolive," [8] and by around 1870, palm oil constituted the primary export of some West African countries. [9] In 1780, Carl Wilhelm Scheele demonstrated that fats were derived from glycerol.
It is related to two other edible oils: palm oil, extracted from the fruit pulp of the oil palm, and coconut oil, extracted from the kernel of the coconut. [2] Palm kernel oil, palm oil, and coconut oil are three of the few highly saturated vegetable fats; these oils give the name to the 16-carbon saturated fatty acid palmitic acid that they ...
Palmitic acid was discovered by Edmond Frémy (in 1840) in the saponification of palm oil, which process remains today the primary industrial route for producing the acid. [13] Triglycerides (fats) in palm oil are hydrolysed by high-temperature water and the resulting mixture is fractionally distilled .
Vegetable oil refining may refer to: Fat hydrogenation, combining vegetable oil with hydrogen to make it more saturated; Edible oil refining, process to refin a raw oil to produce an edible oil, which differ from Olive oil production. Biodiesel production by transesterification; Production of hydrotreated vegetable oil, a biofuel
