E154, also known as Brown 1, is a synthetic colorant used in food products to provide a brown hue. It is commonly found in items like sauces, baked goods, and processed foods. E154 is derived from coal tar and is classified as a food additive. The use of E154 is regulated in many countries, and it is important for consumers to be aware of its presence in food products. While it is generally considered safe for consumption, some individuals may prefer to avoid synthetic additives in their diets.
