As a subject matter expert in the field of food science and additives, I can provide you with an informed answer regarding carmine.
Carmine, also known as cochineal extract, is a red pigment that is derived from the cochineal insects, which are small, dried insects native to Central and South America. These insects live on cactus plants and produce a red dye as a defense mechanism. The process of obtaining carmine involves crushing the insects to extract the colorant. It has been used for centuries as a natural colorant in the food, cosmetics, and textile industries.
However, whether carmine is considered "natural" can be a matter of debate. While it is derived from a natural source, the process of production involves industrial methods, and some people may argue that it is not natural in the sense that it is not a simple, unprocessed ingredient. Additionally, there are concerns about the sustainability and ethical implications of harvesting cochineal insects for colorant production.
In terms of regulations, carmine is recognized as a natural color additive by the FDA in the United States and is listed as E120 in the European Union's list of additives.
