Solvent Extraction Method for Edible Oil Processing

Solvent extraction is a chemical oil extraction method to process oil out from vegetables, oilseeds and nuts by solvent, and Hexane is the preferred choice. Industrial oil processing for the edible oil generally involves the solvent extraction step which may or may not be preceded by pressing. Hexane-based processes have been in commercial operation for a long time. For such processes, it is

Solvent Extraction American Oil Chemists' Society

Put simply, the high oil content makes it difficult to adequately flake the oilseed and cook it for solvent extraction without oil coming free of the seed and fouling equipment. Furthermore, the 40% oil content would require much more than the optimum energy for removal of solvent from miscella in extraction. Therefore, the screw press technology is used before extraction to better prepare the

The production process of vegetable oil involves the removal of oil from plant components, typically seeds. This can be done via mechanical extraction using an oil mill or chemical extraction using a solvent. The extracted oil can then be purified and, if required, refined or chemically altered. Oils can be removed via mechanical extraction, termed "crushing" or "pressing." This method is typically used to produce the more traditional oils (e.g., olive, coconut etc.), and it is preferred by most "health-fo

Sometimes it is necessary to use a solvent in order to extract the oil from certain seeds, nuts or kernels in order to make the extraction cost effective. Once the oil has been obtained, the solvent is then removed from the oil, but a trace percentage of the solvent may still be present in the final oil. Coconut, Palm, Grapeseed and Rice Bran are typically solvent extracted.

During extraction, a solvent normally food grade n-hexane is used to separate the vegetable oil from cellular material. In order to ensure that the solvent enjoys unobstructed access to the interior of the seeds, the cell walls need to be broken down and diffusion pathways need, at the same time, to be kept short. In order to achieve this, seed is heated, where necessary, then
