Calcium carbonate Food Grade
مؤهل وفق ISO 9001:2015 و ISO 14001:2015 · تقديم خدمات للمختبرات والصناعة منذ عام 2000 · شهادة التحليل مع كل دفعة
Calcium carbonate food grade is a white, odorless powder derived from limestone or marble, widely used as a dietary supplement, antacid, and food additive (E170) for acidity regulation, mineral fortification, and as an anti-caking agent in processed foods. It is also used in pharmaceuticals, plastics, and paper manufacturing. This food-grade calcium carbonate has a CAS number of 3983-19-5, with the molecular formula CaCO3 (not Ca(CO3H)2) and a molecular weight of 100.09 g/mol. It is stored at ambient temperatures, carries a signal word of *Warning*, and complies with food safety regulations including FDA 21 CFR §184.1326 and EU E170. Molekula supplies calcium carbonate food grade from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

الأسئلة الشائعة
What is calcium carbonate (food grade) commonly used for?
Food-grade calcium carbonate is primarily used as a dietary supplement (e.g., antacids, calcium enrichment), a food additive (e.g., acidity regulator, anti-caking agent), and in pharmaceuticals like tablets and capsules.
What is the chemical formula and molecular weight of calcium carbonate (food grade)?
The formula is **Ca(CO₃H)₂** (calcium bicarbonate, though often confused with CaCO₃ in food-grade contexts), and the molecular weight is **162.11 g/mol** for the provided structure.
How should calcium carbonate (food grade) be stored?
Store in a cool, dry place at ambient temperature, sealed in its original packaging to prevent moisture absorption or contamination.
What grades of calcium carbonate does Molekula supply, and is food-grade available?
Molekula supplies **food-grade calcium carbonate** (meeting FDA/USP/EP standards) and may offer other grades upon request—confirm specifications during ordering.
Can Molekula supply calcium carbonate in bulk quantities?
Yes, bulk quantities are available; minimum order quantities and packaging options vary—contact sales for custom solutions.
What documentation comes with a food-grade calcium carbonate order?
Orders include a **Certificate of Analysis (CoA)**, **Material Safety Data Sheet (MSDS)**, and **batch-specific documentation** (e.g., FDA compliance for food-grade).
