  • What is the quality of flaxseed oil obtained by supercritical fluid extraction?
  • Quality of flaxseed oil obtained by supercritical fluid extraction (SFE) and accelerated solvent extraction (ASE) was evaluated and compared with that of the conventional solvent extraction (SE). The oil yield obtained by SFE, ASE and SE was 36.49, 41.90 and 42.40 g/100 g, respectively.‌
  • How is flaxseed oil extracted?
  • This work compares the yield and quality of the flaxseed oil obtained by individually optimized supercritical carbon dioxide extraction (SCE), three-phase partitioning (TPP), solvent extraction and the reported values of cold press extraction.‌
  • Which solvent is used to extract oil from flaxseeds?
  • Different solvents are used for extraction of oil from oilseeds including flaxseeds. These solvents include acetone, methanol, petroleum ether, n-hexane dichloromethane, ethanol and heptane. Solvent extraction depends on factors such as nature of solvent, reaction time, temperature and solid/solvent ratio.‌
  • Which extraction method gives the highest yield of oil from flaxseed?
  • Solvent extraction gave the highest oil yield. Oil extracted by SCE showed the best quality in terms of unsaturation and antioxidant activity. Enzymatic pre-treated TPP is a promising approach for extraction of oil from flaxseed as it simultaneously separates protein and oil.‌
  • Does flaxseed oil have low oxidative stability?
  • Low oxidative stability of flaxseed oil necessitates the use of extraction technologies that are advanced and economically viable than the currently used cold press extraction.‌
  • How is flaxseed processed?
  • However, commercial processing of flaxseed is similar to that of other oilseeds and includes seed cleaning, flaking, cooking, pressing, solvent extraction (using n -hexane), and solvent removal steps to yield oil and meal. The amount of heat involved in the processing may influence the quality of the obtained oil.
