Quality evaluation of flaxseed oil obtained by different extraction techniques

► Flaxseed oil was obtained conventionally and by supercritical fluid extraction (SFE). ► SFE showed lower oil yield as compared to the conventional solvent extraction. ► SFE oil showed significantly lower peroxide value and saturated fatty acids. ► SFE oil showed higher iodine value and polyunsaturated fatty acids. ► SFE oil showed significantly higher phenolic acids' content.
