Solvent Extraction of Oil Seed

Traditionally, oil is removed from oilseeds such as rapeseed, soy and cottonseed using tested methods such as the American Oil Chemist’s Society Method Am-2-93. This is a solvent-based method that employs a Soxhlet apparatus to extract oils from oil seeds. The method must be carried out in three stages requiring the apparatus to be disassembled after the first two of three extractions, and the sample reground in mortar before reassembly. The entire process may take as long as 20 hours.

Accelerated Solvent Extraction (ASE®) is an extraction method that significantly streamlines sample preparation. A commonly used solvent is pumped into an extraction cell containing the sample, which is then brought to an elevated temperature and pressure.
Minutes later, the extract is transferred from the heated. Air samples were passed through a solid sorbent tube (4 mm i.d. × 7 cm long) containing 150 mg of impregnated charcoal (Barnebey-Cheney Co., Columbus, OH, No. 580-20, M-2820) at 50–200 mL/min. for 3–5 h. The charcoal was removed to a tube containing 15.0 mL of 0.1% H O and shaken for one hour, then sonicated cell to a standard collection vial for cleanup or analysis.

The entire extraction process is fully automated and performed in minutes for fast and easy extraction with low solvent consumption.
Oils for foods and cooking are derived from oilseeds like canola, soybeans, corn, flax, cotton, etc. The production of oil from oilseeds is an important business, and agronomists are continuing to investigate ways to improve the oil output of the seeds as well as ways to control the composition of the oil itself.
