Question

why are the packets of peanut potato crisps and some others snack foods filled with nitrogen before they are sealed up?​

Answer 1

Answer:

Oxygen is highly-reactive, so this means it likes to combine with other molecules, which results in food spoiling or losing its' freshness. By using nitrogen to be filled in chip bags, the shelf life is extended, and the quality of the chips and snacks are kept. Because food and beverage manufacturers are using nitrogen repetedly, & they are having an nitrogen generator & this can save lots of money and time, compared to finding a supply of nitrogen.
