Oilseed extraction processes are designed to obtain high-quality oil with minimal undesired components, achieve higher yield and obtain a high value-added meal. Two standard processes are mechanical extraction and solvent extraction, and also a combination of both depending on the percentage of oil in the oil-bearing material. Mechanical extraction has lower installation costs and is used for first press oils. Solvent extraction offers higher yields and is economical for OBMs with less oil content.
