Is Nitrogen Safe?
We freeze Ice Cream with liquid nitrogen. Nitrogen is 78 % of the air we breathe and the liquid is a colder form of nitrogen. The fog that occurs when you put
liquid nitrogen on the cream is from the warming of the nitrogen. The
liquid is so cold; it boils away into a gas. The properties are very similar to water.
Water turns to steam when it boils.
Liquid nitrogen has been used in food for a long time. Dippin Dots are

longer. The oxygen in air is what makes food go bad. Nitrogen is the good
You will not find nitrogen on labels because it is a freezing agent. As the
liquid warms it becomes a gas, nothing is left behind in the food.
Nitrogen is an inert gas; it reacts with nothing, and is odorless and
Liquid Nitrogen is safe when used with food. Do not try to deal with liquid nitrogen at home, leave that part to the professionals.
