Why are chips bags filled with air?
How many times have you opened a swollen bag of chips to find that the quantity is very small? Some potato chips are at the bottom of the bag only. Certainly and without any doubt, the question “Why do you fill chips” bags with air?
In fact, these bags do not contain air but nitrogen gas. The reason lies in the need to preserve the taste of the product and prolong its life. And you can understand this more simplified when you open a bag of crispy potatoes, for example, and leave it for a while exposed to the air.
After a few minutes, you will find that the product has lost its crunch and is relatively soft.
The only explanation here is that the oxygen reacts with the fries, making them not crunchy. Therefore, “nitrogen” is simply placed inside the bag to replace the natural air because it does not interact with the food, and thus the crispy potato chips maintain their “vitality” and flavor for as long as possible.
