E150d, also known as caramel color, is a food additive used to enhance the color of various products. It is produced by heating sugars, often in the presence of acids or alkalis, resulting in a dark brown hue. This additive is commonly found in beverages, sauces, and baked goods. E150d is considered safe for consumption and is approved by food safety authorities in many countries. It is important to note that while it adds visual appeal, it does not significantly alter the flavor of the food. Its use is regulated to ensure that it meets safety standards for consumers.
