Liquid nitrogen Wikipedia
Oxygen sensors are sometimes used as a safety precaution when working with liquid nitrogen to alert workers of gas spills into a confined space. Vessels containing liquid nitrogen can condense oxygen from air. The liquid in such a vessel becomes increasingly enriched in oxygen (boiling point 90 K; −183 °C; −298 °F) as the nitrogen evaporates, and can cause violent oxidation of organic material.

How Nitrogen Flushing Protects and Preserves Foods
Jun 27, 2019· The nitrogenfilled packages help to protect the delicate foods inside for as long as the bag is sealed. Of course, once you open the bags, the nitrogen escapes and is replaced by regular air that's about 20 percent oxygen. That means the food inside is no longer protected and will start to deteriorate and the oils or fats will start to go rancid.
