Calcium Citrate
Calcium citrate tetrahydrate from Lianyungang Longtaiwei Food Ingredients Co., Ltd is a white, odorless powder with the molecular formula Ca3(C6H5O7)2·4H2O and a molecular weight of 570.50. It carries CAS number 813-94-5 and exhibits slight hygroscopicity, making it suitable for controlled humidity environments. The compound is nearly insoluble in water and ethanol, and its crystal water content gradually diminishes when heated to 100°C, with complete dehydration occurring at 120°C.
This grade is food-grade calcium citrate, widely used as a chelating agent, buffering agent, and tissue coagulant in the food industry. It is particularly valued for its superior bioavailability compared to calcium carbonate, especially in applications requiring pH neutrality. The product is packed in 25 kg bags, each lined with polyethylene and enclosed in a composite plastic woven outer layer to ensure stability during transport and storage.
Primary buyers include nutraceutical manufacturers, dairy processors, and food fortification programs seeking reliable calcium supplementation. The material is sourced from China and is designed for global export, with storage recommendations emphasizing dry, ventilated, and clean warehouses. Buyers should verify packaging integrity to prevent moisture exposure, as the product must be kept isolated from toxic substances during transportation.

Sourcing Calcium Citrate from Lianyungang Longtaiwei Food Ingredients Co., Ltd - China Import Guide
Before ordering, verify the product’s Certificate of Analysis to confirm it meets food-grade standards for purity, heavy metals, and microbial counts. Request documentation for the CAS number 813-94-5 to ensure the correct compound is supplied, as substitutions can occur with similar calcium salts.
Confirm logistics details such as lead time, Incoterms (e.g., FOB or CIF), and payment terms, as these are not specified in the listing. Given the product’s sensitivity to moisture, insist on intact, dual-layer packaging and check for any signs of damage upon delivery.
For quality control, perform a visual inspection for color and odor consistency upon receipt, and test solubility and calcium content if facilities allow. Request a sortex analysis or third-party lab report for added assurance, especially for large-scale orders intended for nutraceutical use.
