Enrichment of stearidonic acid in modified soybean oil by low temperature crystallisation

► Stearidonic acid (SDA) has health-promoting effects and good oxidative stability. ► We enriched SDA in modified soybean oil by low temperature crystallisation. ► Best conditions were 10% oil:solvent ratio, 24 h, and hexane:acetone (10:90, v/v). ► We obtained 33 g of TAG with 45% SDA concentration and 35% yield. ► 2.5% oil:solvent ratio gave an improved yield (57%) with lower SDA concentration (39%).
