Edible oil production begins with oilseed preparation: cleaning (pre-cleaner, destoner, magnetic separator) removes foreign matter; cracking and dehulling prepares the seed; flaking or grinding increases surface area for extraction. Oil is then extracted by pressing (mechanical expeller or cold press), solvent extraction (typically using hexane in large-scale plants), or a combination of both (pre-press followed by solvent extraction of the residual cake). The extracted crude oil is filtered and then refined through a sequence of stages depending on the intended use: degumming (removes phospholipids), neutralisation (reduces FFA), bleaching (removes colour and oxidation products), and deodorisation (removes volatile off-flavours). RBD (refined, bleached, deodorised) oil is the standard commercial product for cooking oil. The refined oil is then filtered, cooled, and filled into bottles, jerry cans, drums, or IBCs for distribution.
