Characterization of press and solvent extraction oils from new sunflower seeds with modified phytosterol compositions.

Differences in environmental and/or cultivation conditions between harvests may result in substantial differences in the fatty acid composition and phytosterol content in oils from the new sunflower seeds. Rigorous measures and controls to avoid trace metal contamination are required so that the PO can be considered as edible virgin oils. © 2020 Society of Chemical Industry.
