The role of liquid nitrogen in the food industry

Does ice cream production using liquid nitrogen do not harm consumers?

First, let’s briefly explain how to prepare a nitrogen ice cream in a store. The way to make this emerging ice cream is to allow the customer to choose their favorite flavors, mixing these fruits with milk, cream and cacao, making a smooth mix. Then, adding liquid nitrogen (with a negative temperature of 196 ° C) to this compound causes it to freeze and create a texture similar to that of ice cream in a mix that is custom made with the customer’s own flavors.

It’s likely that the newly emerging ice cream will pop up around the corner. But the question asked about this ice cream client is that producing ice cream using liquid nitrogen does not hurt the consumer? Can the health of such a product be assured? Are all age and sex groups allowed to buy and use ice cream nitrogen? For this reason, in this article, to answer these questions and other questions, we will address the answers that Dr Arasab Dabbagh Moghadam, a food hygiene specialist and vice chairman of the Food and Drug Administration’s Food and Drug Administration have made.
 

Does ice cream production work with this method?

In general, ice cream is made from common ingredients such as milk, cream and other ingredients such as fruits, chocolate pieces and so on, so if the seller does not mix the ingredients and make ice cream, this is not the case in other parts of the world. It’s the same thing and it’s the base of ice cream, and it does not matter.

Do ice cream in the industry do the same in the same way?

And smooth ice cream will be produced with a good texture. This is not the case with traditional and homemade ice cream.

What method do ice cream industry use in ice cream?

The cooling method varies in different industries, for example, in the industry, the product enters the freezer and at a temperature between 40-50 ° C, and after freezing, it is removed from the top of the mold, and then, At a negative temperature of 18 ° C.
 

What do you think about using liquid nitrogen to freeze the ingredients in ice cream?

Nitrogen or liquid nitrogen is also a commonly used substance for this purpose. Normally, nitrogen is a neutral gas that has no harmful effects for the human body. And the air we breathe is composed of a lot of nitrogen or nitrogen. Nitrogen in the food industry is used in several ways. One way to use it is to inject gas into food envelopes such as chips and puffs. If nitrogen becomes compressed and converted to a liquid (nitrogen is converted to a liquid at a negative temperature of 196 ° C), it is located in a state that, when removed in the product and the pressure is lost to the gas, This process takes the heat of the environment so that everything that is next to it freezes.
