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 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.
