Spread Ingredients: Interesterified Soybean Oil

Interesterified soybean oil is a type of fat made from soybean oil that has been chemically rearranged through a process called interesterification. This process changes the structure of the fat molecules, giving them different melting properties and textures. It is used to create fats with specific consistencies without creating trans fats.

Manufacturers add interesterified soybean oil to foods to improve texture, stability, and shelf life, often as an alternative to partially hydrogenated oils. It is commonly found in spreads, baked goods, and frozen foods like garlic toast and cinnamon rolls, where it helps provide a desirable mouthfeel and structure.

Interesterified soybean oil is generally recognized as safe (GRAS) by the FDA when derived from GRAS oils like soybean oil. Unlike partially hydrogenated oils, interesterified oils do not contain artificial trans fats, which were largely removed from the food supply due to health concerns. Research on the specific health effects of interesterified fats compared to other fats is ongoing, with some studies suggesting similar metabolic effects to other saturated fats, while others indicate no significant difference from un-modified oils. JECFA has evaluated soybean oil, but specific evaluations for interesterified soybean oil as a distinct additive are not typically highlighted separately from the base oil.
