Alias: Quick-rising powder, leavening powder, fermentation powder, foaming powder
Molecular formula: Mixture (primary component: NaHCO₃)
1、Product Property
Baking powder is a white powdered chemical leavening agent composed of sodium bicarbonate (alkaline), acidic salts (e.g., sodium acid pyrophosphate, tartaric acid), and corn starch as filler. It reacts upon contact with water/heat, releasing CO₂ gas for dough expansion. Dual-acting types react twice (at mixing and baking). It is odorless, soluble in water, and requires dry storage to prevent premature reactions。

3.Application Scope and Usage
Baking powder is essential in baked goods like cakes, muffins, pancakes, and quick breads where yeast fermentation is impractical. It provides immediate leavening without requiring proofing time. Commercial bakeries use it in cookies and biscuits for consistent rise, while households rely on it for homemade baking. The double-acting type is preferred for industrial use as it offers better process tolerance. Usage typically ranges from 2-5% of flour weight. Special low-sodium formulations exist for dietary needs. Strict formulation control prevents over-leavening or metallic aftertastes in final products.
4.Package and Storage
Baking powder is packaged in moisture-proof containers, typically 50g-1kg laminated foil bags for retail or 25kg polyethylene-lined paper bags for commercial use. Storage requires cool (below 25°C), dry conditions with relative humidity under 50% to prevent premature reaction. Containers must be sealed tightly after each use. Shelf life is 6-12 months unopened, reduced to 2-3 months after opening. Exposure to heat or moisture causes clumping and gas loss. Transport as non-hazardous material, but protect from humidity during logistics.
