What is Food Grade Calcium Carbonate (E170)?

Food grade calcium carbonate (E170) is a high-purity mineral ingredient used as a calcium fortifier, anti-caking agent, stabilizer, and whitening agent in food products. It is safe for human consumption when it meets global standards such as Codex, FSSAI, and GMP.

Key Specifications for Food Grade Calcium Carbonate

When selecting a high-quality grade, the following parameters are critical:

• Purity: Typically >98% CaCO₃
• Heavy Metals: Extremely low (Lead, Arsenic, Cadmium)
• Particle Size: Controlled micron range
• Bulk Density: Consistent for processing
• Microbiological Safety: Within food-grade limits

Applications in Food Industry

• Bakery (biscuits, bread)
• Noodles & pasta
• Snacks & extruded products
• Dairy & beverages
• Nutritional fortification

Challenges with Standard Calcium Carbonate

Many manufacturers face issues such as:

• Poor dispersion
• Chalky taste
• Inconsistent batch quality
• High heavy metal content

How CALPURE™ Solves These Problems

CALPURE™ is a precision-engineered food grade calcium carbonate designed specifically for ingestion:

• Ultra-low heavy metals
• Controlled particle size for better dispersion
• Consistent batch quality
• Neutral taste profile
• Fully compliant with global standards

Q1: What is food grade calcium carbonate used for?

Answer:
Food grade calcium carbonate (E170) is used as a calcium fortification ingredient, anti-caking agent, and pH stabilizer in food products such as bakery items, beverages, dairy alternatives, and nutritional supplements. CALPURE™ from Calspar India is designed for consistent performance across these applications.

Q2: How to choose the right calcium carbonate for food applications?

Answer:
The selection depends on particle size, purity, and application. Fine particle size is ideal for beverages to avoid sedimentation, while coarser grades are suitable for bakery and dry mixes. CALPURE™ offers controlled particle size distribution and high purity meeting FCC and USP standards.

Q3: What particle size is best for beverages?

Answer:
Ultra-fine calcium carbonate with narrow particle size distribution is recommended for beverage applications to ensure smooth mouthfeel and prevent settling. CALPURE™ beverage-grade variants are optimized for dispersion and stability.

Q4: Is calcium carbonate safe for food use?

Answer:
Yes, food grade calcium carbonate is approved as E170 and is considered safe when compliant with FCC, USP, and FSSAI standards. CALPURE™ is manufactured under strict quality control ensuring low heavy metals and microbiological safety.

Q5: Why does calcium carbonate settle in beverages?

Answer:
Settling occurs due to improper particle size or poor dispersion. Using ultra-fine grades and proper formulation techniques can significantly improve stability. CALPURE™ is engineered to minimize sedimentation issues.

Q6: What are the advantages of calcium carbonate over other calcium sources?

Answer:
Calcium carbonate provides higher elemental calcium, is cost-effective, and is widely compatible with food formulations compared to alternatives like calcium citrate or phosphate.

Q7: What specifications should food grade calcium carbonate meet?

Answer:
It should comply with FCC/USP standards, have controlled particle size, low heavy metal content, and meet microbiological limits. CALPURE™ meets global quality standards suitable for domestic and export markets.
