What is it?
Potassium carbonate and potassium bicarbonate are inorganic alkaline potassium salts used as acidity regulators and raising agents. On heating or in acid conditions they release carbon dioxide to leaven dough, while also supplying potassium.

In a nutshell
Potassium carbonate and bicarbonate are basic inorganic raising agents and acidity regulators that also supply potassium.
Consumer Advice
Potassium carbonate and potassium bicarbonate are potassium salts used as acidity regulators and raising agents, commonly found in noodles (for a firmer, springy texture), cocoa products, baked goods and beverages. In the body they become potassium and bicarbonate, normal metabolic substances. They are very safe at standard levels, though people with kidney disease or on a potassium-restricted diet should be aware of higher-dose products.
