E-150, commonly known as caramel color, is a food additive used to give a rich brown hue to various products. It is produced by heating sugar, often in the presence of acids or alkalis, which results in a complex mixture of compounds. This coloring agent is widely used in beverages, sauces, and baked goods to enhance their visual appeal. Caramel color is classified into different types based on its production method, with E-150a, E-150b, E-150c, and E-150d being the most common. It is generally recognized as safe by regulatory agencies, including the FDA and EFSA, when consumed within established limits.
