Nitrogen is key to extending the shelf life of packaged foods. It effectively displaces oxygen and moisture which can cause mould, mildew, and other quality issues. During food manufacturing and processing, nitrogen can be used to flush tubes, pipes, and containers before moving the product through the system. Most commonly, nitrogen is used for ‘flushing’, a process that involves placing the food into its container and filling it with nitrogen. This displaces the oxygen, forcing it out of the bag, which is then sealed tightly to prevent the nitrogen from escaping. In addition to increasing the shelf-life of the food, nitrogen also adds a layer of cushioning, which is particularly important for fragile foods such as chips, pretzels, and popcorn. Nitrogen is also useful for vacuum-packing foods as it removes the air inside the package before sealing it.
Nitrogen is also used in bottling. It removes oxygen from the bottle, making it suitable to be stored for longer periods of time. Removing the oxygen also flushes out potential contaminants and minimises oxidation that may cause food spoilage. Bottling with nitrogen also helps to preserve flavours, stop rancidity, and keep its contents fresher for longer. Here at On Site Gas, we work with bottling customers worldwide in developing and expanding the nitrogen generator of choice that best serves each of their unique needs, from the smallest estate to the largest high-volume producer.
