We consume a lot of processed foods without knowing how they are prepared. These foods have become an integral part of modern life. Processed foods require protection from deterioration due to oxidation and moisture. The food has a long way to travel from the processing plant to the grocery store before finally ending up on your kitchen shelves. This movement from the plant to the kitchen also entails time during which time the food requires protection. And, it is not like you would eat up the food soon after getting home. Off course, it is going to lie around the kitchen selves for some time before being consumed.
Nitrogen Flushing in Food Packaging
Processed food is mostly packaged in bags and boxes every day. Durability of the dry foods is ensured by displacing oxygen with nitrogen thus creating an un-reactive atmosphere. Exposure to oxygen causes food to deteriorate due to oxidation. Oxygen is responsible for formation of moisture, mold and bacteria. This will result in fats going rancid and discoloration and eventually wastage of food. There is only one way to ensure protection – nitrogen flushing
What is Nitrogen Flushing?
Nitrogen flushing is a process of removal of oxygen with nitrogen cushioning food content inside the packaging. Being unreactive nonmetallic gas nitrogen does not react with the food unlike oxygen thus ensuring its longevity. You must have noticed snack or chips packaging feeling airy. Well, it is not done to make the packaging feel and look bigger but to protect it from damaging effects of oxygen. The gas is nitrogen commonly used for creating modified atmosphere for preservation of food. It is safe and does not alter the flavor, integrity or texture of the food. In fact, we are exposed to nitrogen all the time since it makes up around 78% of the air we breathe.
How Nitrogen Flushing Can Save You Money?
If you are in the business of packaging food and get nitrogen though cylinders, it is certain that you are paying a lot of money for the gas. At times you will not be getting nitrogen supply on time; as a result, your manufacturing processes will take a hit. This will result in decreased revenues. Under the circumstances, the best solution we recommend is installation of onsite liquid nitrogen plant will meet all your needs with the specified purity and all other specifications.
