Anhydrous calcium acetate food grade powder is a white, odorless, water-soluble calcium salt with the chemical formula Ca(C2H3O2)2, produced to meet food-grade purity standards and used as a preservative, acidity regulator, and calcium fortifier in foods and beverages.
What is anhydrous calcium acetate food grade powder used for?
In food applications, it helps control acidity, extends shelf life, and adds bioavailable calcium. It also appears in pharmaceutical and industrial formulations where a highly soluble calcium source is needed. Because it is anhydrous, it contains no water of crystallization, giving a higher calcium content per gram than the hydrated form.
How is food grade quality determined?
Food grade material must meet strict limits for heavy metals, arsenic, and lead, and is typically tested against recognized purity standards. Buyers should request a certificate of analysis (COA) for each lot to confirm assay, moisture, and particle size. Consistent particle size matters for blending and dissolution in dry mixes.
How do you choose a reliable calcium supplier?
Look for a calcium manufacturer with documented quality systems, stable production capacity, and experience exporting to regulated markets. Many global buyers source from china calcium salts producers because of competitive pricing and mature supply chains. A dependable calcium supplier should provide full traceability, safety data sheets, and responsive technical support.
What should you check before ordering?
- Assay and moisture content on the COA
- Heavy metal and microbial limits
- Packaging, shelf life, and storage conditions
- Regulatory compliance for your target market
Stored in a cool, dry place in sealed packaging, the powder remains stable for extended periods. Always confirm specifications against your formulation needs before bulk purchase.
常见问题
Is anhydrous calcium acetate safe to eat?
Yes, when it is produced to food-grade specifications and used within regulatory limits, it is considered safe for human consumption. It is approved as a food additive in many regions for acidity regulation and calcium fortification.
What is the difference between anhydrous and hydrated calcium acetate?
Anhydrous calcium acetate contains no water molecules in its crystal structure, while the hydrated form does. This makes the anhydrous powder more concentrated in calcium per unit weight, which can be advantageous in dry formulations.
How should anhydrous calcium acetate food grade powder be stored?
Store it in a cool, dry area in tightly sealed containers away from moisture and strong oxidizers. Properly stored, it maintains its quality for the shelf life stated by the manufacturer.
