Phosphate-Free Baking Powder

Phosphate-free baking powder is a leavening agent used in baking that contains no phosphates, compounds whose excessive intake can burden the kidneys and interfere with mineral absorption. Instead of the common sodium pyrophosphate, it typically uses cream of tartar (potassium bitartrate) or another natural acid as its acidic component. When exposed to moisture and heat, it reacts with bicarbonate of soda to release carbon dioxide, which causes the dough or batter to rise. It is particularly suitable for people monitoring their phosphorus intake, such as patients with kidney disease.
