You may think why potato chips packets are filled with nitrogen gas when eating potato chips. Because the oxygen in the air causes the chips to soften, and nitrogen can make the chips have a longer shelf life. A 1994 study showed that nitrogen makes potato chips more delicious.
Why are potato chips oxidized?
Potato chips are high-fat foods. Unsaturated fatty acids in oils and fats are prone to oxidation after contact with air and then deteriorate. Therefore, it is necessary to fill the bag with nitrogen to prevent corrosion. The peroxide value measures the degree of rancidity. Generally speaking, the higher the peroxide value, the more rancid it is.
Why potato chips packets are filled with nitrogen gas?
1. Nitrogen is easy to obtain, low in cost and stable in nature, and is very suitable for use as a protective gas for food.
2. Selecting nitrogen as a fill can reduce weight and reduce transportation costs.
3. Nitrogen is lighter and less dense than air. It is colorless and tasteless, and is different from other gases and does not affect the quality of food.
Advantages of filling nitrogen gas in potato chips packets also have the followings:
1. Oxidation protection
Nitrogen is not active chemically, and it is difficult to react with other substances at room temperature, so it is often used as a preservative.
2. Ensure the integrity of potato chips, easy to transport
Potato chips contain almost no moisture and break easily. Nitrogen filled packaging helps reduce the possibility of chips being crushed during transportation.
