Oxidation is a chemical reaction in which atmospheric oxygen in the air surrounding food and drinks attacks the product. This can occur at or below ambient temperatures (i.e. during normal storage of beverages, oils, fruit & vegetables or finished food products). It can also happen at elevated temperatures, such as during processing or deep-fat frying.
We deliver food-grade nitrogen and other inert gases that prevent or minimize the effects of oxidation. For example, nitrogen is used to keep oxygen levels in and around the product low. An inert atmosphere stabilizes the product and increases its shelf life.
Blanketing is one of three main inerting processes used to avoid oxidation.
The air in the cavity or headspace around a product can contain moisture and oxygen. High-purity nitrogen is completely dry and inert, preventing it from reacting with the product when used to replace the air in packaging. This is a safe and reliable way of protecting food from the effects of oxidation.
We also deliver high-precision valve control systems for filling or emptying food tanks or containers. These valves maintain a constant protective blanket by automatically adjusting the nitrogen content.Nitrogen blanketing is ideal for tanks containing process and finished oils.
