Description

Sodium Aluminum Phosphate is an inorganic compound widely used as a leavening acid and emulsifying salt. Its primary commercial value lies in its ability to provide controlled, consistent reaction rates in baking applications and to stabilize processed food systems. This makes it an essential functional ingredient for manufacturers in the food industry, particularly in the production of baked goods, processed cheeses, and powdered food products.

Application

• Baking Powder Acidulant: A key leavening agent in prepared cake mixes, self-rising flours, and refrigerated doughs, reacting with sodium bicarbonate to release carbon dioxide.
• Processed Cheese Emulsifier: Functions as an emulsifying salt to produce a smooth, homogeneous texture and prevent oil separation in processed cheese and cheese sauces.
• Dairy Product Stabilizer: Used in powdered milk, coffee whiteners, and other dairy-based powders to improve dispersion and solubility.
• Poultry & Meat Processing: Employed as a protein modifier and moisture-retaining agent in injected or marinated poultry and meat products.
• Seafood Processing: Helps retain moisture and improve texture in processed seafood products like surimi.
• Acidulant for Beverages: Can be used to provide a mild, non-reactive acidity in certain dry beverage mixes.
• Industrial Applications: Serves as a binder or flux in ceramics and refractory materials.

Quality Control

Our Sodium Aluminum Phosphate is manufactured under strict quality systems to ensure it meets the stringent requirements of the food industry. Production adheres to relevant food safety standards, including FCC (Food Chemicals Codex) specifications where applicable. Every batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing parameters such as assay, heavy metal content, and loss on drying, ensuring traceability and compliance for our global B2B customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking and degradation due to atmospheric moisture.
