Is colour e150d vegan?

Colour E150d refers to sulfite ammonia caramel, also known as Class IV caramel color, which is a dark brown food coloring. It is manufactured by carefully heating food-grade carbohydrates in the presence of both sulfite and ammonium compounds under controlled temperature and pressure conditions. The starting carbohydrates are sourced exclusively from plants, typically corn, wheat, glucose syrup, or sugar beets. This additive is widely used across the food and beverage industry, commonly appearing in dark soft drinks such as colas, as well as beers, gravies, soy sauces, vinegar, baked goods, and confectionery.

colour E150d is vegan because its production relies entirely on plant materials and chemical reagents of mineral or synthetic origin. Animal-derived ingredients, byproducts, and processing aids are not used at any stage of its synthesis or refinement. Consequently, colour E150d is suitable for individuals following a vegan diet.
