10. Extraction Process
Step 1: Harvesting
Lavender flowers are harvested when they are fully bloomed. Early morning harvesting is often preferred as it may provide higher oil content.
Step 2: Preparation
Fresh or slightly dried flowers are placed into a distillation chamber.
Step 3: Steam Distillation
High-temperature steam is passed through the plant material, causing the oil glands to release their volatile compounds.
Step 4: Vapor Collection
The mixture of steam and essential oil vapors is directed into a condenser, where it cools and returns to liquid form.
Step 5: Separation
The essential oil separates naturally from the hydrosol (floral water). Since the oil is lighter than water, it floats on the surface and can be collected.
Step 6: Filtration and Storage
The extracted oil is filtered and stored in dark-colored glass containers to preserve its quality and stability.
