Partially Hydrogenated Sunflower Oil

Partially hydrogenated sunflower oil is a type of sunflower oil that has been chemically changed through a process called partial hydrogenation. This process adds hydrogen atoms to the oil, making it more solid at room temperature and extending its shelf life.

Historically, manufacturers used partially hydrogenated sunflower oil to improve the texture and stability of processed foods. It helped make products like baked goods and snacks creamier or more solid, and also helped prevent spoilage.

In the US, partially hydrogenated oils (PHOs) are no longer considered Generally Recognized As Safe (GRAS) by the FDA since 2018. This change was made because PHOs are the main source of artificial trans fat in the diet. Artificial trans fat is known to increase "bad" cholesterol (LDL) and decrease "good" cholesterol (HDL), which can raise the risk of heart disease. The FDA's action effectively removed most artificial trans fats from the US food supply.
