Edible Oils & Fats

BOC provides gases to prevent the deterioration of oils and fats through the production and packing processes so that they maintain their quality and shelf life.

Edible Oils & Fats

Collaborating closely with its customers over the decades, BOC has gained valuable insights into the ways that oils, fats and foods with a high oil or fat content can be protected against deterioration as a result of oxidation. The answer lies in protecting the oil and improving its stability. The best way of achieving this is by making sure that oxygen does not come into contact with the product at any stage in the production process.  

Well-oiled partnership 

We can help you achieve this, for example, by replacing harsh physical/chemical preservative methods with a gentle inerting solution using nitrogen (N2). Nitrogen does not interact directly with the product. It is thus the ideal agent to displace atmospheric air (and thus oxygen) and water vapour to avoid oxidation. 

Drawing on our deep understanding of both quality and safety requirements, we have developed a range of inerting and other solutions to stabilise oil and fat products at all processing stages. 

We also offer gas-enabled application technologies to support blanketing, purging and sparging, hydrogenation and fluffing.  

Gases

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. 

Supply

Cylinders

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.

Cryospeed

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. 

Bulk

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.
