What Is Sodium Bicarbonate?

Sodium bicarbonate, commonly known as baking soda, is one of the most widely used food additives in the world. It is a weak alkaline compound that releases carbon dioxide gas when it reacts with an acid, causing doughs and batters to rise. It is also found naturally in mineral springs. As a food additive, it is extremely well-characterized and has been used in baking for over 150 years.

What Is It Used For?

Primary leavening agent in quick breads, cakes, muffins, pancakes, and cookies. Acts as an acidity regulator in various food applications. Also used to soften legumes during cooking and as a natural cleaning agent.
