solvent extraction method for edible oil processing

Solvent Extraction Method for Edible Oil Processing

The extraction system can be generally put into two categories, one is direct solvent extraction, the other is a pre-press system followed by solvent extraction. In general, a pre-press system followed by solvent extraction may be an option when the oilseed contains more than about 23% oil.

The seed is mechanically pressed (pre-pressed) to extract approximately half to three-quarters of the obtainable oil so that the solvent extraction can be run more efficiently. This is typical for seeds having more than 20% oil. The solvent extraction procedure uses hexane or other solvents to wash the sunflower oil from the prepared flakes.

Solvent extraction method is an oil extraction method using solvent such as n-hexane to help oil extraction. This method gives a high oil yield from oilseeds. However, the oil extracted using this method has a low oil quality since the solvent does not only dissolve the oil from oilseeds, but also dissolve other undesirable components from ...
