Quick Answer: Annatto is a natural orange-red colorant from achiote seeds, used in cheese, butter, and snacks. It is generally considered safer than artificial dyes. However, rare cases of food intolerance and allergic reactions have been documented, particularly IgE-mediated reactions.
Annatto (also called achiote or E160b) is a natural food coloring derived from the seeds of the Bixa orellana plant, native to Central and South America. It gives cheddar cheese, butter, margarine, Goldfish crackers, and many snack foods their orange-yellow color. Annatto is widely considered a safer alternative to artificial dyes like Yellow 5 and Yellow 6. However, it is not entirely without concerns: several case studies have documented allergic reactions to annatto, including hives, angioedema, and anaphylaxis. A 2009 study in the Annals of Allergy, Asthma & Immunology confirmed IgE-mediated allergy to annatto extract. For the vast majority of people, annatto is safe and well-tolerated — but people with known sensitivities to natural colorants should be aware of its presence.
