CAS 471-34-1 Explained: Everything Food Manufacturers Should Know About Food-Grade Calcium Carbonate

The food manufacturing industry depends on safe, consistent ingredients suitable for many uses. Whether producing dairy products, bakery items, beverages, confectionery, or nutritional supplements, manufacturers need raw materials that support product quality while meeting regulatory standards. One such widely used ingredient is food grade calcium carbonate, recognized globally by CAS 471-34-1. 

Known for its high purity and versatility, calcium carbonate (CAS number 471-34-1) is used as both a calcium source and a functional ingredient in many food products. It is commonly available as white calcium carbonate powder, making it easy to incorporate into different formulations without changing the product's taste, smell, or appearance.  

At Pyoraa, we understand that every ingredient plays an important role in the final product. We supply high-quality food grade calcium carbonate that delivers reliable quality, consistent performance, and dependable supply for food manufacturers.  

In this guide, we explain everything you need to know about CAS 471-34-1, helping you make informed decisions for food production and ingredient sourcing. 

Why Is CAS 471-34-1 Important for Food Manufacturers? 

Every ingredient used in commercial food production must be accurately identified. Since many materials may have different trade names across countries or industries, a standard identification system helps avoid confusion. This is where CAS 471-34-1 becomes important. 

This unique number assigned by the Chemical Abstracts Service identifies calcium carbonate worldwide, enabling manufacturers, suppliers, regulatory bodies, and quality teams to refer to the same substance regardless of brand or region. 

Using the correct CAS number offers several practical advantages. 

• Ensures accurate ingredient identification 
• Supports raw material traceability 
• Simplifies procurement documentation 
• Helps maintain regulatory compliance 
• Reduces sourcing errors 

For food manufacturers, verifying CAS 471-34-1 is often one of the first steps in confirming that the correct ingredient has been sourced. 

What Makes Food Grade Calcium Carbonate Different? 

Not all calcium carbonate is suitable for food. Different uses need different quality levels. food grade calcium carbonate is manufactured and tested according to applicable food-grade quality and safety requirements. 

Food-grade calcium carbonate is subject to specifications and quality controls appropriate for its intended food application. It also meets food industry standards. 

Some of its defining characteristics include: 

These qualities make food grade calcium carbonate suitable for manufacturers looking to maintain product consistency while supporting nutritional value. 

Where is Calcium Carbonate Used in Food Products? 

One of the biggest advantages of calcium carbonate for food is its versatility. It serves multiple purposes across different food categories without significantly affecting flavour or product appearance. 

Some common food applications include: 

• Dairy products 
• Milk powders 
• Bakery products 
• Breakfast cereals 
• Confectionery 
• Nutritional supplements 
• Beverage mixes 
• Processed foods 

Because calcium carbonate can serve different functions depending on the formulation, it is used across a range of food manufacturing applications. 

Why is White Calcium Carbonate Powder Preferred in Food Production? 

Appearance is an important quality parameter in food production. Consumers expect food products to have a uniform colour and consistent visual appeal. Even small variations in raw materials can affect the final product. 

A high-quality white calcium carbonate powder offers excellent brightness and fine particle distribution, making it easier to blend into food formulations. 

Its benefits include: 

• Uniform colour consistency 
• Smooth mixing during production 
• Better ingredient dispersion 
• Improved formulation consistency 
• Reliable batch-to-batch performance 

These characteristics make white calcium carbonate powder suitable for manufacturers aiming to maintain high product standards across different production batches. 

How Does Calcium Carbonate Support Food Manufacturing? 

Modern food manufacturing requires ingredients that perform multiple roles while remaining stable throughout processing. calcium carbonate for food offers this flexibility, making it valuable across different formulations. 

Beyond providing calcium, calcium carbonate can also contribute functional properties in specific formulations. 

Its functional benefits include: 

• Calcium enrichment 
• Consistent ingredient performance 
• Improved product stability 
• Neutral taste profile 
• Compatibility with different food formulations 
• Reliable processing characteristics 

Since calcium carbonate (CAS number 471-34-1) remains stable under normal food processing conditions, manufacturers can incorporate it into various products without compromising formulation quality. 

What Should You Check Before Purchasing Food Grade Calcium Carbonate? 

Choosing the right ingredient supplier involves more than reviewing pricing. A reliable supplier should consistently deliver materials that meet quality expectations while providing complete technical documentation. 

Before purchasing food grade calcium carbonate, manufacturers should assess several important factors. 

Reviewing these factors helps manufacturers select calcium carbonate for food that aligns with both production needs and quality standards. 

What Should Food Manufacturers Know About Food Grade Calcium Carbonate Specifications? 

Understanding food grade calcium carbonate specifications is essential before adding any ingredient to a food formulation. These specifications help manufacturers determine whether the material meets the required quality, purity, and safety standards for food applications. 

Manufacturers should review technical data before supplier approval, considering more than basic purity to ensure consistent ingredient performance. 

The following parameters are commonly evaluated: 

Reviewing food-grade calcium carbonate specifications before procurement helps manufacturers reduce quality variation and maintain consistency across production batches. It enables procurement and quality teams to make informed decisions based on technical performance, not just cost. 

How Can Manufacturers Choose the Right Calcium Carbonate Supplier? 

Consistent ingredient quality also depends on supplier controls, manufacturing practices, documentation, and supply-chain reliability, maintain quality control, and support regulatory compliance with documentation. 

When evaluating suppliers of calcium carbonate for food, manufacturers should consider more than availability and pricing. 

A reliable supplier should offer: 

• Consistent product quality across every batch 
• Clear technical specifications and supporting documents 
• Reliable packaging for safe transportation and storage 
• Traceability throughout the supply chain 
• Timely deliveries to avoid production delays 
• Responsive technical support when required 

Building a long-term relationship with a trusted supplier reduces sourcing risks and supports uninterrupted manufacturing operations. 

Why Are Quality Documentation and Traceability Important? 

Food safety regulations continue to evolve, making documentation a critical part of ingredient sourcing. Every raw material should be supported by records that verify its identity, quality, and compliance with applicable standards. 

For calcium carbonate food additive, proper documentation helps manufacturers demonstrate due diligence during customer audits and regulatory inspections. 

Important documents may include: 

• Certificate of Analysis 
• Product specification sheet 
• Batch identification records 
• Safety documentation where applicable 
• Quality certifications 

Together with food grade calcium carbonate specifications, these documents help manufacturers validate that the supplied material is suitable for food use and meets internal quality requirements. 

Making the Right Choice for Food Manufacturing 

Choosing the right food ingredient is an important step in producing safe, high-quality, and consistent food products. Understanding CAS 471-34-1, reviewing food grade calcium carbonate specifications, and selecting a reliable supplier all contribute to better manufacturing outcomes. From maintaining formulation consistency to supporting nutritional value and regulatory compliance, food grade calcium carbonate continues to play an important role across the food industry.
