Steam Distillation: A Traditional Approach to Rosemary Oil Production
Materials Required
– Fresh rosemary leaves or sprigs
– Distillation apparatus (still, condenser, boiler)
– Heat source
– Glass or metal container for collecting oil
– Thermometer
– pH meter
Process Overview
Steam distillation is a method that utilizes steam to extract volatile compounds from plant material. In the case of rosemary oil production, steam is passed through a chamber containing rosemary leaves or sprigs. The steam carries the volatile compounds, including rosemary oil, through the condensation process.
Detailed Procedure
1. Preparation: Crush or chop fresh rosemary leaves or sprigs to increase surface area for steam penetration. Fill the still with the prepared rosemary material, leaving some headspace for steam expansion.
2. Heating: Apply heat to the boiler to generate steam. The steam rises through the still, carrying the volatile compounds along.
3. Condensation: The steam and volatile compounds enter the condenser, where they cool and condense back into a liquid. The condensed liquid separates into two layers: an aqueous layer (hydrosol) and the rosemary oil layer.
4. Collection and Separation:
The rosemary oil layer, being less dense than water, floats on top of the hydrosol. The oil is carefully collected into a separate container using a graduated cylinder or pipette. The pH of the hydrosol can be measured to ensure minimal oil loss.
| Process Step | Temperature Range |
|---|---|
| Heating | 100-120°C |
| Condensation | 40-60°C |
Hot Pressing: A Modern Method for Extracting Rosemary Oil
Hot pressing is a modern extraction method using advanced technology to efficiently extract rosemary oil from botanical sources. This process involves several stages:
