Can liquid nitrogen be eaten?

When mentioning the term liquid nitrogen, many things will come to mind. For example, in medicine, there is liquid nitrogen cryotherapy, which is a relatively advanced treatment method. For example, it can treat skin diseases such as warts. In addition, in many places, people like to drink liquid nitrogen cocktails, which is an ultra-low temperature wine that tastes very refreshing. In short, the temperature of liquid nitrogen is very low, so can liquid nitrogen be eaten directly?

Can liquid nitrogen be eaten?

Liquid nitrogen is not as scary as you might think. The moment you drink it, it will quickly vaporize, forming a nitrogen protective film between the liquid nitrogen and the mouth. Since the thermal conductivity of the gas is very poor, the liquid nitrogen will quickly vaporize and will not cause any harm to you. But I couldn't swallow it, and I couldn't shut my mouth. There are many similar phenomena. Similar phenomena will occur when contact with extremely high temperature liquid in a very short period of time. When water drops fall on the red-hot iron plate, they will be separated by the water vapor and will not vaporize quickly. If the temperature of the iron plate is not high enough and the water can come into contact with the iron plate, the vaporization speed will be faster.

Liquid nitrogen is a liquid nitrogen gas with a temperature as low as minus 196 degrees Celsius. The extremely cold temperature makes liquid nitrogen an outstanding refrigeration effect in industry and food preservation. So can vegetables frozen with liquid nitrogen be eaten? Will the taste change? An experiment tells you the answer.

A handful of garlic sprouts were frozen in liquid nitrogen. After they were taken out, they turned into a pile of powder with just a pinch of the hand. It seems that the liquid nitrogen froze all the moisture in the garlic sprouts, so the garlic sprouts became very fragile and could be directly pinched into powder. It seems that garlic sprouts are not suitable for preservation by liquid nitrogen.

The garlic sprouts and cabbage frozen by liquid nitrogen are the same. After losing their moisture, they become so dry that they break into pieces with a pinch. Such vegetables cannot be cut with a knife. If you hold them in your hands with a little force, they will turn into powder. How can you use them to cook?

But cauliflower is different. After being frozen with liquid nitrogen, the whole cauliflower is frozen like a piece of ice. It cannot be cut into pieces with a knife. You can only use a hammer to smash it off a little! Although liquid nitrogen can refrigerate food, it doesn’t seem to be suitable for refrigerating vegetables! Have you thought of this result?

Don't do that. Even a small amount of nitrogen enters the body. It may also vaporize quickly and cause damage to the gastrointestinal tract.

Guidance:

And low temperature can also cause damage to your health. There have been cases of death from drinking liquid nitrogen or beverages containing liquid nitrogen. Don't mess around.
