Food can contain nitrogen like:
Fish
Shellfish
Sardines
Almonds
Hazelnuts
Walnuts
Sesame seeds
Garbanzo
Pinto
Kidney beans
Peanut butter
High-fat meats
Lean pork
Liquid nitrogen can freeze and solidify objects by rapidly lowering their temperature. This causes the molecules in the objects to slow down and become rigid, making them brittle and easily breakable. Liquid nitrogen can cause structural damage to objects and materials, especially those not designed to withstand extreme cold temperatures.
Liquid nitrogen does not freeze instantly; instead, it evaporates rapidly at room temperature. When it comes into contact with objects, such as food or skin, the extreme cold temperature of liquid nitrogen can cause rapid freezing of the water content in those objects, giving the appearance of instantaneous freezing.
Solid nitrogen is called "nitrogen ice" or "nitrogen snow".
Liquid nitrogen has a very low temperature of around -196°C, which is much colder than the freezing point of water. When an object is submerged in liquid nitrogen, its high thermal conductivity quickly transfers heat away from the object, causing it to freeze rapidly. This rapid cooling process can solidify or freeze objects almost instantly.
There are four known chlorides of nitrogen: nitrogen trichloride (NCl₃), nitrogen dichloride (NCl₂), nitrogen monochloride (NCl), and nitrogen tetrachloride (NCl₄).

Nitrogen compounds are found in foods, fertilizers, poisons, and explosives. Nitrogen gas is used as a blanketing medium during the production of electronic components. Nitrogen is also used in annealing stainless steels and other steel products. Liquid nitrogen is used as a refrigerant. Although nitrogen gas is fairly inert, soil bacteria can 'fix' nitrogen into a usable form, which plants and animals can then utilize. Nitrogen is a component of all proteins. Nitrogen is responsible for the orange-red, blue-green, blue-violet, and deep violet colors of the aurora

A collar is usually a part of a garment which goes around the neck of the wearer. By extension, the term is also used for objects which encircle things. This has nothing to do with nitrogen.
Objects that won't burn include: metal, asphalt,nitrogen,argon,helium, etc.
Nitrogen is a gas at room temperature and pressure, so it doesn't have a specific temperature. When liquid nitrogen is in contact with objects at room temperature, it can appear very cold because of its extremely low temperature of around -196 degrees Celsius.
The air has nitrogen in it. I think most plant based foods (such as spinach) contain nitrogen (it is used as a fertilizer in soil, so I assume it's a necessary mineral for plant growth). Possibly also in aerosol propellant canisters (such as squirty cream or hair mousse).
In general ... No. Gaseous Nitrogen has little or no place in an near future space settlements. It is not needed in current space ventures - except to reduce oxygen partial pressure near the Earth's surface.
Objects such as ice cubes, frozen metal, and liquid nitrogen are examples of things that are very cold. These objects have had their temperature significantly reduced through various means, resulting in their cold properties.
Nitrogen is a gaseous element, that is, what is in nitrogen is nitrogen.
