  • 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.
  • Is SCE a safe method for flaxseed oil extraction?
  • The use of carbon dioxide and its recycla- bility make SCE an economical and safe (Pradhan et al. 2010) process and hence a method of choice for flaxseed oil extraction.
  • Does solvent extraction of flaxseed improve oil extraction?
  • Although solvent extraction of flaxseed gives maximum oil extraction, it results in considerable deterioration of the same (Bozan and Temelli 2002; Pradhan et al. 2010).
  • 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.
  • How to separate flaxseed oil from fat?
  • Flaxseed oil can be easily separated by simple decantation below 25 °C, making TPP a very cost-effective, unique and industrially scalable extraction method. None of the other methods studied herein have the advantage of simultaneous separation and extraction of pro- teins and fat.
  • Is flaxseed a good source of edible oil?
  • Flaxseed has gained significant interest as a source of edible oil that is rich in omega-3 fatty acids, high content of flaxseed proteins and lignans that are known to be therapeutic.
