Calcium Phosphate Calcium phosphate is a mineral salt composed of calcium and phosphate ions, essential for bone health and widely used as a food fortificant and stabilizer. In the food industry, it serves as a calcium source in fortified products, acts as a dough conditioner in baking, and provides anti-caking properties in powdered mixes while buffering pH in beverages. It enhances nutritional value in dairy alternatives and prevents spoilage in processed cheeses.
