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 ...
In the food industry and biochemistry, interesterification (IE) is a process that rearranges the fatty acids of a fat product, typically a mixture of triglycerides.The process implies breaking and reforming the ester bonds C–O–C that connect the fatty acid chains to the glycerol hubs of the fat molecules.
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
Extraction De Smet expanded its portfolio of technologies for oils & fats processing: preparation and extraction (1946), oil refining (1963), grain handling and feed milling (1975 – co-operation with Stolz), fat modification (1983).
Hydrotreated vegetable oil (HVO) is a biofuel made by the hydrocracking or hydrogenation of vegetable oil. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation adds hydrogen to molecules. These methods can be used to create substitutes for gasoline, diesel, propane, kerosene and other chemical feedstock.

Expeller processing cannot remove every last trace of liquid (usually oil) from the raw material. A significant amount remains trapped inside the cake remaining after pressing. In most small-scale rural situations this is of little importance, as the remaining cake after oil extraction finds uses in local dishes, in the manufacture of secondary ...
In the processing of edible oils, the oil is heated under vacuum to near the smoke point or to about 232 °C (450 °F), [33] and water is introduced at the bottom of the oil. The water immediately is converted to steam, which bubbles through the oil, carrying with it any chemicals which are water-soluble.
