Oxidation of Fats and Oils
- When fats and oils are exposed to air, they undergo a chemical reaction known as oxidation.
- Oxidation occurs due to the reaction of fats and oils with oxygen in the air, leading to the formation of compounds like aldehydes, ketones, and peroxides.
- This oxidation process is responsible for the phenomenon of rancidity, which results in a bad smell and taste in the food.
EXPLANATION:
- When fat and oil containing food materials are left outside for a long time:
- The fats and oils react with oxygen present in the air.
- This reaction causes the fats and oils to oxidize, forming new compounds that degrade the quality of the food.
- Oxidation is the primary reason for rancidity, which makes the food unfit for consumption over time.
Hence, the correct answer is Option 1: Fats and oils in the food get oxidized.
Therefore, when fats and oils in food are left outside for a long time, they get oxidized, leading to rancidity.
