Sodium bicarbonate is a versatile alkaline compound with multiple applications in baking, cleaning, and personal care. In baking, it acts as a leavening agent, producing carbon dioxide gas when combined with acidic ingredients to create lift and texture in cakes, biscuits, and quick breads. Beyond the kitchen, it serves as a gentle abrasive for surface cleaning, a natural deodoriser for refrigerators and carpets, and a soothing ingredient in bath soaks. Food-grade sodium bicarbonate is chemically pure and safe for culinary use when measured accurately. Store in a cool, dry place away from moisture to maintain effectiveness.
