Shortening Soybean Oil

Shortening is a solid fat, typically made from vegetable oils like soybean oil. It is created through a process called hydrogenation, which adds hydrogen to liquid oil, making it more solid and stable. This process also affects the fatty acid profile, potentially creating trans fats, though modern methods aim to minimize this.

Manufacturers use shortening as a fat source in baked goods to provide tenderness, flakiness, and a smooth texture. Its solid form at room temperature makes it ideal for creating distinct layers in pastries like croissants and for preventing gluten development in cakes and cookies. It is commonly found in cakes, cupcakes, cookies, pastries, and some frozen desserts.

Soybean oil is generally recognized as safe (GRAS) by the FDA for use in food. It is a common source of polyunsaturated and monounsaturated fats. While hydrogenation can create trans fats, which the FDA has determined are not GRAS for use in food, manufacturers have largely reduced or eliminated trans fats in shortenings. The WHO has advised limiting saturated and trans fats in the diet.
