ts baking soda

Baking soda, chemically known as sodium bicarbonate (NaHCO₃), is an alkaline salt compound derived from natural mineral deposits or synthesized through the Solvay process. It appears as a white crystalline powder with a slightly bitter, alkaline taste. Unlike baking powder, which contains additional acidic components, pure baking soda requires an acid (such as buttermilk, lemon juice, vinegar, or molasses) to activate and produce carbon dioxide gas, which leavens baked goods. When heated above 50°C, baking soda begins to decompose, releasing CO₂, water vapor, and sodium carbonate.

Baking soda functions primarily as a chemical leavening agent in baking, creating rise and lightness in cakes, cookies, muffins, and quick breads when combined with acidic ingredients. It is essential in recipes for soda bread, pancakes, waffles, and traditional Irish brown bread. Beyond baking, baking soda is used to tenderize meat by breaking down proteins, to reduce bitterness in vegetables, and as a component in Asian noodle alkaline treatments. It also neutralizes acidic flavors in sauces and soups, making it valuable in both sweet and savory applications.
