While learning to cook, Rajesh noticed that when he crushed a dozen of groundnuts in a grinder, it gets lined with oil. Whereas no oil is released when he grinds a bowl of cumin. What could be the reason behind this difference?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. The fat in groundnut releases oil.
The correct reason is that the fat in groundnut releases oil. Groundnuts are rich in fats and oils, so when they are crushed or ground, the mechanical action breaks their cell walls, releasing oil that lines the grinder. On the other hand, cumin seeds contain mainly essential oils in very small amounts, not stored fats, so no visible oil is released when they are ground. Thus, the difference arises due to the high fat content in groundnuts compared to cumin.
