Rose oil is extracted from rose leaves using ____________ distillation?
Correct answer: D. Steam
- A. High pressure
- B. Low pressure
- C. Extractive
- D. Steam
Explanation
Rose oil is volatile and heat-sensitive, so it is recovered by steam distillation at a temperature lower than its normal boiling point. Steam carries the oil vapour over without requiring high-temperature boiling of the oil itself.
