Fun Facts About Nitrogen

It’s all about the nitrogen!

We decided to use liquid nitrogen to freeze our ice cream scoops because it creates a smoother, creamier texture. Liquid nitrogen sits at -196 degrees celsius and freezes ice cream within minutes, creating smaller ice crystals compared to conventional ice cream machines that take an average of 20-30 minutes. The end result? Silky smooth ice cream.

Liquid nitrogen ice cream is completely safe and in case you’re wondering what nitrogen is, here are some facts about it:

  • Nitrogen is non-toxic, odorless, and colourless.
  • It is not flammable.
  • Nitrogen gas is slightly lighter than air once it reaches room temperature. It is slightly soluble in water.
  • Nitrogen was first liquefied on April 15, 1883, by Polish physicists Zygmunt Wróblewski and Karol Olszewski.
  • Nitrogen is 75% of the air we breathe.
  • All living things contain nitrogen, mostly in amino acids, DNA, and RNA.
  • The human body contains about 3% nitrogen, making it the fourth most prevalent element after oxygen, carbon and hydrogen
  • Nitrogen is required to build amino acids.
  • Many plants are able to synthesize nitrogen directly from the soil so that it forms proteins digestible from the plants’ leaves.
  • Liquid nitrogen is stored in special insulated containers that are vented to prevent pressure build-up. Depending on the design of the dewar or flask, it can be stored for hours up to a few weeks.
  • Liquid nitrogen in food was first mentioned in an 1890 recipe book titled “Fancy Ices” authored by Mrs. Agnes Marshall, an English culinary entrepreneur.

One Review

  1. Thank you for all the fun facts on nitrogen. After having some flash frozen ice cream, my son has been asking about it. That is really cool that nitrogen is 75% of the air we breathe. I didn’t know that.
