Food Grade Calcium Chloride Dihydrate Flakes - Product Datasheet & Specifications
Product Name: Food Grade Calcium Chloride Dihydrate Flakes
Synonym: Calcium Chloride 2-Hydrate, Food Grade CaCl2·2H2O, E509 Calcium Salt
Chemical Formula: CaCl2·2H2O
CAS Number: 10035-04-8
EINECS Number: 233-140-8
Product Description
Food Grade Calcium Chloride Dihydrate Flakes are high-purity, white crystalline flakes obtained through the refining and controlled crystallization of purified calcium chloride solution. This product contains ≥99% CaCl2·2H2O and provides an effective, safe, and versatile source of calcium ions for use in food, beverage, pharmaceutical, and nutritional applications.
Produced in compliance with FCC (Food Chemicals Codex) and E509 (EU food additive) standards, this material exhibits excellent solubility, rapid dissolution, and strong hygroscopic properties. It is widely used as a firming agent, stabilizer, coagulant, and electrolyte in a variety of food systems. The flakes are free from magnesium, sulfate, and heavy metal impurities, ensuring consistent performance in sensitive applications.
Thanks to its balanced calcium content (approx. 27% Ca) and neutral taste, it is ideal for calcium fortification, cheese production, canning, and brewing. Each batch is processed under ISO 9001, ISO 22000, and HACCP certified systems to ensure purity, traceability, and food safety compliance.
