Recent Advances in Seed Oil Extraction Science: A Review

There is a variety of methods that are employed to extract oil from seeds. Many of these methods are based either on physical processes or on chemical processes. Traditional extraction methods such as mechanical pressing were compared with more modern extraction methods such as supercritical extraction method. Various options that are available for the extraction of oil from many different seeds were discussed. These extraction processes depend on a number of factors for product yield, safety and other considerations. For health, safety and environmental issues, recent developments in oil extraction procedures have seen the adoption of supercritical fluids in order to produce cleaner and greener extracts with high yields.
