Fatty acid composition and iodine value
Fatty acid methyl esters (FAME) synthesized from silflower oil were separated using an Agilent Technologies (Palo Alto, CA) 6890N GC fitted with a flame ionization detector and a Supelco (Belefonte, PA) SP2380 30 m × 0.25 mm column. The peaks were identified using a standard mix of saturated FAME (C8 to C30) and mono- and poly-unsaturated C14, C16, C18, C20, C22 and C24 (Nu-Check Prep, Elysian, MN). The details of the FAME preparation and GC parameters are available elsewhere (Chakraborty et al., 2018). The iodine value (IV) of the oil was calculated from the fatty acid composition according to AOCS Cd1-85 (AOCS, 2017).
