Can Ultrasound-assisted extraction increase the yield of flaxseed oil?
In contrast, ultrasound-assisted extraction is more suitable for large-scale production and has better development and application potential, it could significantly increase the yield of flaxseed oil by 11.5%, and the extraction rate of PUFAs by 68.12% (Ranveer, Gutte, & Sahoo, 2015; Long et al., 2011).
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.
Why is flaxseed oil not used in food industry?
In recent years, the production and application of flaxseed oil have become one of the most concerned research topics in food industry due to its multiple health functions, great potential and development prospects. However, the poor stability and easy oxidation of flaxseed oil have become the main factors limiting its application.
