E120, also known as carminic acid, is a natural colorant derived from the cochineal insect. It is commonly used in food products, cosmetics, and textiles to provide a red hue. The extraction process involves drying and crushing the insects, which are then processed to obtain the dye. This colorant is often labeled as cochineal extract or carmine on product packaging. E120 is considered safe for consumption by regulatory agencies, but some individuals may have allergic reactions. It is important for consumers to check labels, especially those with dietary restrictions or sensitivities.
