Product Overview & Executive Summary
Food Grade Anhydrous Calcium Chloride Balls - Product Datasheet & Specifications
Product Name: Food Grade Anhydrous Calcium Chloride Balls
Synonym: Food Grade CaCl2 Spherical Granules, Calcium Chloride Anhydrous Pellets, E509 Calcium Salt
Chemical Formula: CaCl2
CAS Number: 10043-52-4
EINECS Number: 233-140-8
Product Description
Food Grade Anhydrous Calcium Chloride Balls are high-purity, white spherical granules produced through spray granulation and dehydration of refined calcium chloride solution. This specialized process results in smooth, uniform, and dust-free balls with high hardness and excellent hygroscopic performance. The product contains ≥94% CaCl2 on a dry basis and delivers outstanding solubility, rapid dissolution, and high calcium concentration (~36%).
Compared to flakes or powders, the spherical form offers superior handling, minimal dusting, and controlled release properties. It is particularly suited for food, beverage, and pharmaceutical uses where precision dosing, moisture absorption, and consistent performance are required.
Produced under ISO 9001, ISO 22000, and HACCP management systems, this food-grade product fully complies with FCC (Food Chemicals Codex), E509, and GB 1886.45 standards, ensuring safety, purity, and traceability throughout production and packaging.
