Product Overview & Executive Summary
Food Grade Anhydrous Calcium Chloride Powder - Product Datasheet & Specifications
Product Name: Food Grade Anhydrous Calcium Chloride Powder
Synonym: Anhydrous CaCl2, Food Grade Calcium Chloride, E509 Calcium Salt
Chemical Formula: CaCl2
CAS Number: 10043-52-4
EINECS Number: 233-140-8
Product Description
Food Grade Anhydrous Calcium Chloride Powder is a highly purified, white crystalline powder produced through evaporation and dehydration of food-grade calcium chloride solutions. This process ensures a CaCl2 content ≥94%, making it an effective, safe, and versatile calcium source for food, beverage, and pharmaceutical applications.
Compared with dihydrate forms, the anhydrous grade provides higher calcium concentration, greater drying efficiency, and lower water content, ideal for formulations requiring moisture-sensitive stability. It exhibits excellent solubility, rapid dissolution, and strong hygroscopicity, allowing quick binding of free moisture in food systems and packaging environments.
The product complies with FCC, GB 1886.45, and E509 standards and is manufactured under ISO 9001, ISO 22000, and HACCP certified systems. Its fine, free-flowing texture and consistent chemical composition make it suitable for food processing, nutritional fortification, beverage clarification, and desiccant applications.
