Question

it is recommended to use air tight containers for storing oil for a long time

Answer 1

it is recommended to use really airtight container to store oil because the airtight container contains no air. The air causes rancidity of oil. If there is no air in the container or a very little amount of air is there, then it can prevent or at least slow the process of rancidity.

Answer 2

1. Air , heat , light affects the quality of edible oil, which deteriorate through oxidation (Rancidity).

2. The oxidation process is greatly enhanced when edible oil is stored in containers that are not air tight and in areas where oil is exposed to air, heat and light.

3. Hence, it is recommended to use air tight containers for storing oil for a long time to prevent it from getting oxidised.
