Is e133 vegan?

E133 is a synthetic food colorant that is also known as Brilliant Blue FCF. It is a bright blue powder that is commonly used in the food industry to add color to a wide range of products, including sweets, drinks, and baked goods. E133 is made by combining benzene with sulfuric acid and then treating the resulting compound with sodium nitrite and hydrochloric acid. It is approved by the European Union and the United States Food and Drug Administration for use in food products, and it is considered safe when consumed in moderate amounts. However, some studies have suggested that E133 may be associated with allergic reactions and hyperactivity in children, so it is important to use it with caution.
