Chips are packaged with extra space to prevent crushing, but the gas inside is nitrogen, not oxygen. Nitrogen preserves the chips while oxygen would make them soggy and spoil.
The chips are specially packaged with extra space to act as a cushion and prevent them from being crushed during handling. But it’s actually not oxygen that takes up so much space in the bags: it’s nitrogen, the gas that makes up 78 percent of the air we breathe. Nitrogen remains stable around other chemicals, making it a useful preservative. On the other hand, oxygen reacts with nearby substances. If the bags of chips were filled with oxygen, the potatoes and oil in the chips would end up getting soggy from the moisture and eventually spoiling.
