Background of Nitrogen Generators for Modified Atmosphere Packaging

From the moment food leaves the production line, the deterioration period begins due to bacteria, yeast, mold, and moisture in the air. For food manufacturers and processors, the goal is to delay this spoilage to maintain quality and allow more time for products to reach consumers.

One of the most effective ways to achieve this and extend product shelf life is by using Modified Atmosphere Packaging (MAP) technology.

MAP uses nitrogen to replace the oxygen content in food packaging, thereby prolonging the preservation time of products. Additionally, it creates a pressurized atmosphere that provides extra protection.

Advantages of Nitrogen Generators for Modified Atmosphere Packaging

Using industrial nitrogen generators to produce your own nitrogen not only eliminates the ongoing costs of bulk transportation and storage but also offers a safer option for other production facilities. Furthermore, nitrogen generators play a crucial role in MAP.

The main advantages of nitrogen generators for modified atmosphere packaging include:

(1) Extended Shelf Life: Sometimes referred to as "gas flushing" or "oxygen reduction packaging," MAP involves removing natural air from packaging materials and replacing it with nitrogen. Since nitrogen is inert, it behaves neutrally with food and does not promote the decomposition process.

(2) Cost Reduction: In addition to lowering costs, MAP gives food manufacturers and processors better control over their products. On-demand nitrogen supply prevents downtime if bulk supplies run out or cylinders need replacement.

(3) Increased Sales: Once products reach grocery stores, sellers can ensure product quality, leading to higher sales. With extended shelf life, manufacturers can also expand export opportunities to new geographic regions. Moreover, MAP technology helps reduce recalls and product returns due to spoilage.

(4) Improved Display: MAP allows products to maintain freshness for longer periods with minimal need for chemical preservatives. Using nitrogen in MAP also helps preserve the final product's flavor, color, texture, taste, and aroma while retaining its nutritional value.
