Unpleasant taste and foul smell in fatty food are caused due to ____. (dehydration / rancidity).
1. Rancidity
Fatty foods contain fats and oils. When exposed to air, they get oxidized, due to which food gets spoiled. This process is called rancidity.
2. Explanation
The process that involves the removal of water molecules from any substance is termed as dehydration. Dehydration does not cause any foul smell or unpleasant taste. Rancidity spoils the food materials prepared in oils and fats which have been kept for a considerable time and makes them unfit for eating.
Hence, unpleasant taste and foul smell in fatty food are caused due to rancidity.`
