Meeting consumer demands for variety, quality and freshness with food-grade gases for chilling, freezing, packaging, transport cooling, carbonation and inerting applications

Steaks on the grill

BOC works closely with the food industry to develop and deliver diverse solutions including cryogenic freezing and chilling, modified atmosphere packing (MAP) and transport, cooling and dry ice applications. Our gases - whether in cryogenic liquid form for freezing or as a gas mixture for food packing - help customers to improve productivity, optimise solutions and maximise ROI. This ensures food meets rising consumer demand and is healthy, safe, minimally processed and attractively packed.

Our dedicated team of field and in-house specialists will work with you to develop a tailored solution to meet your productivity needs. Our Food Technology Centre (FTC) in Thame, Oxfordshire, offers the opportunity for customers to trial and test new products.

The specialist food team can guide you through all the options - from freezing, chilling and packing equipment through to gas supply options and food transportation possibilities.

All food grade gases supplied by BOC meet strict food standards legislation and have traceability and safety guarantees and required by law.


Carbon Dioxide (CO2) 

Carbon dioxide is used in Modified Atmosphere Packing (MAP) to inhibit the growth of fungi and bacteria

Liquid carbon dioxide is used in cryogenic freezing & chilling applications

Carbon dioxide is used in the carbonation of fizzy drinks and for food inerting applications

Oxygen (O2)

Oxygen is used in Modified Atmosphere Packing (MAP) to maintain the quality, flavour, texture and appearance of food

Nitrogen (N2) 

Nitrogen is used in Modified Atmosphere Packing (MAP) to prevent oxidation and reduce odours 

Liquid nitrogen (LIN) is used in cryogenic freezing & chilling applications 

Nitrogen can also be used for food inerting applications and for increasing the strength of plastic drinks bottles

Gas Mixtures 

Oxygen, nitrogen and carbon dioxide can be combined in various quantities to produce the ideal preservation gas for any food type. 



BOC Food Fresh cylinders and Manifolded Cylinder Pallets (MCP) have been developed for food businesses using modified atmosphere packaging (MAP).

Food Fresh cylinders can be supplied as single gases or as mixtures. Your BOC sales and technical specialist will advise on the appropriate mixing equipment, or pre-mix cylinders. Where a pre-mix gas is chosen, BOC will advise on the exact gas mixture for packing your product.


BOC’s Cryospeed service gives you access to larger volumes of oxygen, nitrogen and carbon dioxide in cryogenic liquid form. These are stored in fully maintained stainless steel vacuum-insulated vessels on your site and are filled by our Cryospeed operators. Our storage vessels are set up for the pressures, flow rates and sizes appropriate to each customer. All rented vessels are fully maintained under the supply agreement with BOC. 


High gas volumes can be stored in BOC bulk cryogenic vessels. These are installed at the customer’s site, providing a continuous and secure supply of oxygen, nitrogen or carbon-dioxide. Our Customer Engineering Service (CES) designs, installs and maintains the vessel in line with customer requirements and in compliance with all the relevant regulations (such as the Pressure Systems Safety Regulations 2000). Our On-Stream service can also cover customer-owned systems.  

On-site generation 

For those needing generated nitrogen, the BOC Ecovar-mini range provides an on-site generation solution at a range of pressures, flow rate and purity. On-site generation requirements are assessed on a site-specific basis to ensure the resulting set-up will cater for your needs now and in the future.
