Abstract:
Flaxseed oil, derived from the seeds of Linum usitatissimum, is known for its high omega-3 fatty acid content, particularly alpha-linolenic acid (ALA). This study compares the chemical composition and physicochemical properties of flaxseed oil extracted using two methods: cold pressing and solvent extraction. The results indicate that cold pressing preserves higher levels of bioactive compounds such as tocopherols and sterols, while also maintaining better oxidative stability. A significant difference was found in the fatty acid profile, with cold-pressed oil containing higher amounts of ALA. These findings suggest that cold pressing is a superior method for producing high-quality flaxseed oil, suitable for functional foods and dietary supplements.
