The process that separates volatile oil from the water layer in essential oil production is called?

• A. Distillation
• B. Maceration
• C. Fermentation
• D. Extraction

Answer: (A)

Distillation relies on differences in volatility to separate components. In essential oil production, steam distillation pushes volatile oil components into vapor with the steam. When that vapor condenses, it yields an oil–water mix because essential oils are immiscible with water and the oil typically forms a separate layer. This allows the oil to be collected separately from the water. The steam approach also protects delicate aroma compounds by keeping temperatures lower. Maceration and fermentation involve soaking or microbial changes rather than separating a volatile oil from water, and extraction uses solvents rather than the steam-driven separation of oil from the water layer.
