Answers
Answer:
The answer is
Explanation:
Oxidation of food stuffs leading to change in taste and smell is called rancidity.
chips packets are stuffed with Nitrogen to prevent oxidation.
antioxidants such as BHA and BHT are also used to prevent it.
Refrigeration and salting too prevents oxidation
When fats and oils are oxidised, they become rancid and their smell and taste change.
To prevent rancidity antioxidants (which prevent oxidation) are added to foods containing fats and oils. Rancidity can also be prevented by flushing out oxygen with an inert gas like nitrogen. For example, packets of food items like chips are flushed with nitrogen so that these can be used even after long duration. Keeping food in air tight containers also help to slow oxidation and to preserve food for a longer time.
