Why do edible oils show rancidity when stored for long period?

Text Solution

Verified by Experts

Rancidity occurs due to the oxidation of oils and fats which results in foul smell and change in taste.
ii. When edible oil or ghee is left aside for a long period without use, it reacts with atmospheric oxygen, gets oxidized and becomes rancid i.e., unfit for use. If food is cooked in such oil, its taste changes.

Read the paragraph and answer the questions given below: Renewable energy is energy produced from sources that do not deplete or can be replensied within a human's life time. The most common examples include wind, solar, geothermal, biomass, and hydroelectric power. This is in contrast to non-renewable energy is derived directly or indirectly from the sun. Sunlight can be captured directly using solar technologies. The sun's heat drives winds, whose energy is captured with turbines. Plants also rely on the sun to grow and their stored energy can be utilized for bioenergy. Not all renewable energy sources rely on the sun. For examples, geothermal energy utilizes the Earth's internal heat, tidal energy relies on the gravitational pull of the moon, and hydroelectric power relies on the flow of water.
