Calcium chloride anhydrous food grade bulk refers to the desiccant and firming agent supplied in large quantities for food processing, with a purity suitable for edible use. It is the anhydrous form (CaCl₂), meaning it contains little to no water, which makes it highly effective at moisture control.
What is calcium chloride anhydrous food grade used for?
In food production, it firms canned vegetables and fruit, stabilizes cheese and beer, and acts as a desiccant in packaging. Bulk buyers often choose the anhydrous grade because it absorbs more moisture per kilogram than the dihydrate form.
How do you choose a calcium supplier for bulk orders?
Look for a calcium manufacturer that provides a certificate of analysis, food-grade certifications, and consistent particle size. Many buyers source from china calcium salts producers, but verifying audit reports and traceability is essential before committing to large volumes.
What should you check before buying calcium chloride anhydrous food grade bulk?
Confirm the assay (typically 94–97% CaCl₂), heavy metal limits, and packaging format. A reputable calcium supplier will also clarify storage requirements, since anhydrous calcium chloride is hygroscopic and must stay sealed.
常见问题
Is anhydrous calcium chloride the same as the dihydrate form?
No. Anhydrous calcium chloride contains virtually no water, while the dihydrate form contains about 25% water by weight. The anhydrous grade is more concentrated and absorbs more moisture, which is why it is preferred for certain food and packaging applications.
How should bulk calcium chloride anhydrous food grade be stored?
Store it in a cool, dry place in sealed containers, because it readily absorbs moisture from the air. Keep it away from direct sunlight and separate from incompatible materials to maintain food-grade integrity.
What certifications should a food-grade calcium supplier provide?
A reliable supplier should offer a certificate of analysis for each batch, along with evidence of food-safety compliance such as ISO 22000 or FSSC 22000. Ask for heavy metal test results and a clear traceability record before placing a bulk order.
