Various techniques have been proposed for the extraction of oil from flaxseed, mainly including mechanical processing, solvent extraction, supercritical/subcritical fluid extraction, and microwave/ultrasonic -assisted 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.
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 ).
Does cold press extraction increase flax se Ed oil yield?
cold press met h od in t h e extractio n of flax se ed oil. It was co n cluded that e nz ymatic extraction increased t h e oil yield from 5 to 16.4%. ─── Ukrainian Food Journal. 2018. Volume 7.
