Food grade CO₂ cylinder use in food and beverage production

A food grade CO₂ cylinder is a critical component in many food and beverage processes where carbon dioxide comes into direct or indirect contact with consumable products. From carbonation and dispensing to packaging and preservation, the quality and specification of CO₂ directly affects product safety, taste and regulatory compliance.

Blended Products Ltd supplies ISBT food grade CO₂ to commercial customers across the UK, supporting controlled, traceable and compliant gas use within regulated environments.

What is food grade CO₂

Food grade ISBT CO₂ is carbon dioxide that meets recognised purity and safety standards for use in food and beverage applications. It is produced, handled and filled under controlled conditions to prevent contamination.

Key characteristics include:

·       defined purity limits for food contact

·       controlled moisture and hydrocarbon content

·       full batch traceability

·       compliance with relevant food safety regulations

A cylinder food grade CO₂ is clearly identified and filled specifically for food-related use, separating it from industrial-only gas supplies.

Why food grade specification matters

Using non-certified CO₂ in food environments introduces unnecessary risk. Even small variations in purity can affect product quality or lead to non-compliance during audits.

Food grade CO₂ is required where gas is used for:

·       carbonation of beverages

·       dispense systems for soft drinks and beer

·       modified atmosphere packaging

·       food preservation and chilling processes

·       ingredient processing and handling

A food grade CO₂ cylinder ensures that gas quality aligns with both operational and regulatory requirements.

Applications of food grade CO₂ cylinders

Beverage production and carbonation

CO₂ provides controlled carbonation for bottled drinks, mixers and sparkling water. Consistent gas quality ensures stable taste and mouthfeel.

Dispense systems

Bars, restaurants and commercial kitchens rely on food grade CO₂ to deliver drinks safely through pressurised dispense systems.

Food packaging

In modified atmosphere packaging, CO₂ helps extend shelf life by inhibiting microbial growth and slowing oxidation.

Food processing environments

CO₂ is used in chilling, freezing and processing applications where gas may be present in production areas.

Storage and handling considerations

Food grade CO₂ cylinders must be stored and handled correctly to maintain gas integrity.

Best practice includes:

·       segregating food grade cylinders from industrial gases

·       using compatible regulators and fittings

·       maintaining clean storage areas

·       following inspection and servicing schedules

·       ensuring staff understand food safety requirements

Blended Products provides guidance to help customers maintain compliance throughout the supply chain.

Choosing the right food grade CO₂ cylinder

Selecting the appropriate food grade CO₂ cylinder depends on:

·       consumption volume

·       application type

·       space and storage constraints

·       refill frequency

·       equipment compatibility

Blended Products supplies a range of cylinder sizes and refill options to match different operational needs, from small hospitality systems to larger production environments.

Frequently asked questions

What is the difference between food grade CO₂ and industrial CO₂?

Food grade CO₂ meets stricter purity and handling standards suitable for food contact, while industrial CO₂ is intended for non-food applications.

Is food grade CO₂ required for beverage dispense systems?

Yes. Any CO₂ used in beverage dispense systems should be food grade to ensure safety and compliance.

How can food grade CO₂ cylinders be identified?

They are clearly labelled and supplied with documentation confirming food grade status and traceability.

Can food grade CO₂ be used in packaging?

Yes. Food grade CO₂ is widely used in modified atmosphere packaging to extend shelf life.

Does Blended Products supply food grade CO₂ refills?

Yes. Blended Products Ltd supplies and refills food grade CO₂ cylinders in line with regulatory and quality standards.
