Step-by-Step: How to Make Rosemary Hydrosol Scientifically

How to Make Rosemary Hydrosol? Detailed Explanation Using Scientific Methods

Latin Name: Rosmarinus officinalis L.

Rosemary hydrosol is an aromatic and aqueous product obtained by steam distillation of the leaves and flowers of the rosemary plant. Its chemical structure differs from essential oils.

Obtaining Rosemary Hydrosol: Methods and Explanations

Question: What is rosemary hydrosol and how is it obtained?

Answer: Rosemary hydrosol (Rosmarinus officinalis L.) is produced using techniques such as hydrodistillation or steam distillation. In these processes, the plant material is either boiled directly in water or treated with steam.

• Distillation
• Hydrodistillation
• Steam Distillation
• Condensation
• Distillate
• Florentine flask (Separator Funnel)
• Phytochemicals
• Terpenes
• Hydrophilic compounds
• Organoleptic analysis

Rosemary Hydrosol Production: Step-by-Step Explanation

Question: What are the stages of rosemary hydrosol production?

1. Harvest and Preparation: Plant material is collected and cleaned.
2. Preparing the Distillation Unit: Material is placed into the distillation device.
3. Starting the Distillation: Steam is passed through the plant material.
4. Condensation: Steam is cooled and turned into liquid.
5. Separation of Hydrosol: The distillate is separated using a separator funnel.
6. Quality Control: Organoleptic and physicochemical tests are conducted.
7. Storage: Hydrosol is stored in a cool and dark environment.
