Anti-Caking Agents — Complete E-Number Guide
Anti-Caking Agents are food additives (mainly numbered E500–E599) that prevent powders and granules clumping. Found in table salt, icing sugar, dried soups and baking powder. Every additive below links to its full safety, vegan and halal breakdown.
A handful of additives below carry E-numbers outside the E500–E599 band — they're grouped here because they do the same job in food, not because of their number; the EU/UK E-number system groups by main series but reassigns some additives by function.
