How is linseed oil extracted?

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.

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.

What is linseed oil?

Key words: linseed oil, fatty acids, extraction yield, extraction methods, oil quality Linseed ( Linum usitatissimum) oil contains 40¨C50% ¦Á-linolenic (¦Ø-3) acid, which is rich in phytosterols and tocopherols.

Which solvent is used for linseed oil extraction?

Pradhan et al. ( 3) and Khattab and Zeitoun ( 14 ), using supercritical CO 2 as a solvent for linseed oil extraction, at 3·10 7 Pa and 50 °C for 3 h and 4·10 7 Pa and 50 °C for 2 h obtained 35.3 and 36.5% yield, respectively.
