E903 – Carnauba wax
Glazing agentDescription
Hard, brittle, yellowish-brown wax obtained from the leaves of the Brazilian palm *Copernicia prunifera*
Notes
Carnauba wax comes from the leaves of a palm tree called Copernicia prunifera, which grows naturally in Brazil. The palm produces this wax to protect its leaves from the intense heat and sun of the Brazilian climate. To harvest it, workers collect the leaves and beat them to remove the wax flakes, which are then refined and purified into a hard, glossy wax that's prized for its durability and shine. In food production, carnauba wax works as a glazing agent – essentially a natural coating that gives products a shiny, appealing finish while helping to prevent moisture loss. You'll most commonly find it on candies (especially gummy sweets and chocolate-coated treats), fresh fruits like apples and citrus that have been waxed for longer shelf life, and some pharmaceutical tablets and supplements where it provides a smooth, glossy coating. Carnauba wax is completely natural and plant-based, making it suitable for vegetarians, vegans, and all religious dietary requirements. It's considered one of the hardest natural waxes available and is so safe that it's used not only in food but also in car waxes and cosmetics. Food safety authorities around the world, including the FDA and European Food Safety Authority, have approved it for food use with no specific intake limits because it passes through the digestive system without being absorbed.
