Nitrogen is an inert gas. The oxygen in air - contributes to food going bad quickly, and also changes the flavour of food over time. Replacing the air inside food packaging with nitrogen- prolongs shelf life and flavour.
To prevent them from becoming oxidized
to avoid bacteria
To make food last longer in storage.
Nitrogen acts like an inert gas and stops the food from spoiling
cuz,it avoids the growth of microbes.
Nitrogen gas is a very stable and inert due to its triple covalent bond in the molecular form, N2. Thus it does not react with the food and maintains the freshness of the content of the food packet. Conversely, oxygen can oxidise food and turn them rancid, and provide an environment for bacteria to grow which can result in food spoilage.
Yes, but only if they are in sealed packets.

milk is sold in sealed air tight packets and it prevents the attack of microbes.thats why the milk that comes in packets does not spoil

As with most gasses, nitrogen is usually sold in metal canisters with a valve at the top (like the kind you see people filling baloons with Helium from). Alternately, liquid nitrogen is available for sale and comes in a sealed canister.
Do not enclose liquid nitrogen in a sealed container, as this may result in bursting or an explosion due to pressure buildup caused by the evaporation.
