Sunflower Oil

What this is

Sunflower oil is an edible oil pressed from sunflower seeds, commonly used for deep frying in fast-food outlets and snack foods. It contains mostly unsaturated fatty acids (around 20% monounsaturated, ~69% polyunsaturated) and only ~11% saturated fat. While this high unsaturated profile and a high smoke point make sunflower oil appear heart-friendly, repeated high-heat use can break it down into reactive compounds like aldehydes. Additionally, trace chemicals formed during industrial refining (such as 3-MCPD and glycidyl esters) have raised safety concerns in toxicology reviews.
