Gaseous nitrogen is used in a variety of systems and processes in the food manufacturing and packaging industries. Often regarded as the industry standard for non-chemical preservation, nitrogen is an inexpensive, readily available option. Suited for a variety of uses, Nitrogen needs to be monitored for purity and potential contaminants. Depending on the type of use, the distribution channel, and the required purity levels, different testing plans should be implemented to ensure safety.
Uses For Nitrogen In Food Process
Because foods are comprised of reactive chemicals, it is the job of packaging specialists and food manufacturers to find ways to protect nutrients and ensure the quality of their product. Oxygen can be harmful to packaged foods as this gas causes the food to oxidize and can encourage the growth of microorganisms (Welt and Connaughton, 2017). Foods that are particularly susceptible to these risks include fatty meats, fish, veggies and ready-to-eat products. In fact, a third of fresh food does not reach consumers due to transport spoilage (Sengupta, 2017). Modifying the atmosphere of the packaging can be an effective way to ensure that products remain safe for consumers.
