Question

Spice oils are extracted by a process known as:

• A. Fermentation
• B. Steam distillation
• C. Sublimation
• D. Milling

Hint:

Steam distillation is widely used for extracting essential oils from plants and spices, as it ensures that the volatile compounds are not destroyed by excessive heat.

Answer 1

The Correct Option is B

Spice oils, which are essential oils derived from various spices, are extracted using the process of steam distillation. This method involves passing steam through the spice material, which causes the essential oils to evaporate. The vapors are then condensed back into liquid form, separating the essential oils from the rest of the plant material.
Let's review the options: - Fermentation (Option 1) is not correct because it involves the breakdown of organic substances by microorganisms, typically used for alcohol or bread production.
- Sublimation (Option 3) is incorrect because it refers to the transition of a substance from solid to gas without passing through the liquid phase, which is not relevant to the extraction of spice oils.
- Milling (Option 4) refers to grinding or crushing, not an extraction method, and hence is also incorrect.
Thus, steam distillation is the correct process for extracting spice oils.
