Proven technology keep food bettter longer.
The use of preservation gas makes the NRS different from traditional. Mold and many other micro organisms require oxygen for metabolism  and the nitrogen from the NRS displaces this oxygen killing the micro organisms.
The NRS makes technology already in use by the food industry available to general consumers. In fact, controlling oxygen levels has been proven effective in preserving apples, bananas, oranges, and other fruits and vegetables. Similar technology is also used in the processed food industry where items such as potato chips and bread are often packed in modified atmosphere packaging. This packaging includes nitrogen gas to prevent staling. Grains are often exposed to low levels of oxygen to ensure that they remain contaminant free.
Refrigerators and freezers generally operate at temperatures below forty degrees fahrenheit, which is too cold for many foods. The NRS maintains temperatures around fifty degrees fahrenheit. This is a perfect temperature zone for produce that should not be refrigerated or frozen as well as several other foods such as wine or bread.
The nitrogen system can be used independently. A hose with touch control lets you fill plastic storage containers and bottles with specialized lids and corks for expanded storage and refrigeration.
