Sodium Bicarbonate, also known as baking soda, is a versatile ingredient used primarily as a leavening agent in baking. It reacts with acidic components to produce carbon dioxide gas, which causes dough and batter to rise and become light and fluffy. In addition to its leavening properties, Sodium Bicarbonate can also be used to regulate pH levels and improve texture in various food products. It is a staple ingredient in baking and cooking applications.
