E263

E263 is a chemical compound with the formula C10H14O3. It is a white crystalline powder that is soluble in water and ethanol. E263 is a food additive classified as an acidity regulator. It is commonly used in the food industry to adjust the acidity of food products, such as beverages, sauces, and processed meats. The compound is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and is approved for use in various countries around the world. E263 is produced through the esterification of citric acid with ethanol, resulting in a mixture of mono-, di-, and triethyl esters. The primary use of E263 is to prevent the precipitation of calcium salts in food products, which can cause cloudiness or other undesirable effects. It is also used to enhance the flavor and texture of food. E263 is non-toxic and has a low acute toxicity, making it a suitable choice for food applications. However, like any food additive, it should be used in accordance with established regulations and guidelines to ensure the safety and quality of food products.
