Sugar Esters of Fatty Acids and the Pescatarian Diet

Sugar esters of fatty acids, also known as sucrose esters of fatty acids or E473, are emulsifiers commonly used in the food industry. They are created by combining sucrose, a natural sugar, with fatty acids that can be derived from either plant or animal sources. These esters help to improve the texture and stability of processed foods by facilitating the mixing of water-based and oil-based ingredients.
