Food Grade Sodium Bicarbonate Baking Soda with 99% Purity Soluble in Water for Leavening Agent and Fire Extinguishers

Sodium Bicarbonate (chemical formula: NaHCO₃), commonly known as baking soda, is a versatile inorganic compound widely used across food, pharmaceutical, industrial, and environmental sectors. It typically appears as white, odorless powder or fine crystals, soluble in water (with a slightly alkaline aqueous solution) and stable under normal temperature—decomposing into sodium carbonate, water, and carbon dioxide only when heated above 50℃.

• Chemical Formula: NaHCO₃

• Appearance: White powder or fine crystals

• Odor: Odorless

• Taste: Slightly salty and cool

• Solubility: Soluble in water and glycerol, slightly soluble in ethanol (some sources say insoluble)

• Density: 2.20 g/cm³

Food Processing

• Leavening Agent: Sodium bicarbonate is widely used as a leavening agent in baking. It decomposes when heated, releasing carbon dioxide gas, which causes dough to rise, resulting in light and airy baked goods like bread, cakes, and cookies.

• Carbonated Beverages: It is used as a source of carbon dioxide in carbonated drinks, providing the characteristic fizz.

• Food Preservative: Sodium bicarbonate can act as a preservative in butter and other dairy products, extending their shelf life.

• Vegetable Processing: It is used as a color stabilizer for green vegetables. Adding 0.1% to 0.2% sodium bicarbonate to water can help maintain the green color of vegetables during cooking.

• Flavor Enhancer: It can be used to enhance flavors and improve the texture of certain foods.

Industrial Uses

• Fire Extinguishers: Sodium bicarbonate is used in the production of acid-base and foam fire extinguishers. When heated, it decomposes to release carbon dioxide, which helps to smother fires.

• Rubber Industry: It is used in the production of rubber and sponge products, aiding in the vulcanization process.

• Metallurgy: Sodium bicarbonate serves as a flux in the casting of steel ingots, helping to remove impurities.

• Mechanical Industry: It is used as a molding aid in the casting of steel (sand casting) to improve the quality of the molds.

• Textile Industry: Sodium bicarbonate acts as a fixing agent, pH buffer, and after-treatment agent in dyeing and finishing processes. It helps prevent color bleeding and improves the quality of wool washing.
