Nitrogen gas is an eminent and most popular gas used for modified atmosphere packaging (the practice of modifying the composition of the internal atmosphere of a food or drug package so as to increase the shelf life of the food). Places, where Nitrogen for food processing is used, include food packaging, mixing, coating, freezing, and grinding. While packing food, displacing oxygen and purging nitrogen allows the shelf life of the food products to increase dramatically. Increased shelf life means less food wastage and happier customers.
Increased shelf life because of Nitrogen
Modified atmosphere packaging is the most eminent method used for food preservation because in this method oxygen is taken off and the package is filled with nitrogen. It is necessary to remove oxygen from the food because oxygen helps bacteria such as mildew and mold to grow. Nitrogen for food preservation is important because it fills each and every place in the package letting no moisture to get in the package. A great amount of company’s waste is reduced using Modified atmosphere packaging. It also lets the company save a lot of money.
Deciding the level of nitrogen for food preservation
When a company practice modified atmosphere packaging, it is necessary to work out on the level of nitrogen for food preservation. There is no one level that will suit all type of off packaging. There are many characteristics that are needed to be taken care of. Below are listed some characteristics are to be given thought to while practicing modified atmosphere packaging.
- The organic shelf life of food- If the food that is to be packed is prone to food spoilage quickly; it will require more nitrogen for food preservation as compared with foods that have a better shelf
- Though nitrogen is the only gas utilized in modified atmosphere packaging. There are some kinds of food that can be packed using a mixture of different gases (usually nitrogen and carbon dioxide). Foods that have high moisture contents require around 99.9% nitrogen.
- Storage constraints- Level of nitrogen for food preservation largely depends on the storage condition of food items. If the food is to be refrigerated or frozen, it requires less nitrogen and if it is to be stored at room temperature, the packaging will require more nitrogen.
