This work aims at characterizing linseed oil obtained using different extraction methods (hexane, subcritical propane and pressurized ethanol), and comparing the results with commercial linseed oil extracted by cold mechanical press method.
Who invented linseed oil extraction machines?
Alfred W. French Sr. founded French in 1900 to produce state-of-the-art equipment for the extraction of linseed oil from flax. Mr. French soon adapted his equipment to other oilseeds as well. Today, French stands as a leading supplier and innovator of oil extraction machines and mechanical oilseed screw presses.
Is linseed oil extraction economically viable?
Extraction using organic solvent (Soxhlet) gave a 36.12% yield. Extraction using subcritical propane at 10 7 Pa and 40 °C for 1.5 h gave a better yield (28.39%) than pressurized ethanol (8.05%) under similar conditions. Linseed oil extraction using subcritical propane was economically viable, resulting in a 124.58 US$/L product cost.
Can subcritical propane extract linseed oil?
Linseed oil extraction using subcritical propane was economically viable, resulting in a 124.58 US$/L product cost. The results present subcritical propane extraction as a promising alternative for obtaining linseed oil at mild temperature and pressure conditions, without losing quality and quantity of fatty acids such as ω-3, 6 and 9.
