Sucralose is a zero-calorie artificial sweetener commonly used as a sugar substitute in various food and beverage products. It is derived from sugar through a chemical process that replaces three hydrogen-oxygen groups with chlorine atoms. This modification makes sucralose much sweeter than sugar, allowing for smaller amounts to achieve the same level of sweetness. Approved by the U.S. Food and Drug Administration (FDA) in 1998, sucralose is often found in diet sodas, sugar-free snacks, and baked goods. It is heat-stable, making it suitable for cooking and baking. While generally recognized as safe, some individuals may experience digestive issues when consuming large amounts.
