Mica

Mica is a naturally occurring group of silicate minerals, which are rock-forming minerals. For use in food, mica is typically ground into a fine powder and processed to create a shimmering, pearlescent effect.

Mica is primarily used as a color additive to impart a metallic or pearlescent sheen to foods. It is commonly found in decorative elements for baked goods like cakes and cupcakes, as well as in candies and dessert toppings, to enhance their visual appeal.

Mica-based pearlescent pigments are approved by the FDA as color additives for specific food uses. They are generally considered safe for consumption at approved levels. The European Food Safety Authority (EFSA) has evaluated potassium aluminum silicate (E 555), a component often found in mica-based pigments, and concluded it is safe for use as a food additive. JECFA has also evaluated this substance. There are no major safety controversies regarding mica's use as a food additive, and it is not among the petroleum-based synthetic dyes targeted for phase-out by the FDA.
