E505 – Ferrous carbonate
Acidity regulatorDescription
A grayish-green to brownish-yellow powder; practically insoluble in water, soluble in acids
Notes
Ferrous carbonate is an iron compound that appears as a grayish-green to brownish-yellow powder. It's made by combining iron with carbonic acid (the same mild acid that gives carbonated water its slight tang) under controlled manufacturing conditions. The iron used can come from various sources, but it's processed to create a stable, food-grade form that the human body can absorb and use. This additive serves as an iron supplement and nutritional fortifier in foods. You'll find it added to breakfast cereals, flour, baby foods, and other products that are fortified with iron to help prevent iron deficiency. Iron is essential for making healthy red blood cells and preventing anemia, which is why it's commonly added to staple foods that many people eat regularly. Ferrous carbonate is a synthetic compound, though it provides the same type of iron that occurs naturally in foods like red meat and leafy greens. It's suitable for all dietary preferences including vegetarian and vegan diets, making it a valuable iron source for those who don't eat meat. The amount used in food fortification is carefully regulated to provide nutritional benefits without exceeding safe intake levels.
