Extraction Process
Cardamom Essential Oil is primarily obtained through the Steam Distillation method, which is considered the most reliable and widely accepted extraction technique.
Step 1: Selection of Raw Material
Carefully matured and high-quality cardamom pods are selected.
Step 2: Seed Separation
The seeds are separated from the pods and thoroughly cleaned.
Step 3: Drying and Crushing
The seeds are lightly dried and gently crushed to help release the oil-bearing glands.
Step 4: Loading the Distillation Unit
The prepared seeds are placed into a stainless-steel distillation chamber.
Step 5: Steam Distillation
Hot steam is passed through the seeds, causing the essential oil to vaporize and rise with the steam.
Step 6: Condensation
The vapor mixture is cooled through a condenser, converting it back into liquid form.
Step 7: Oil Separation
Since the essential oil is lighter than water, it naturally separates and is collected using a separator.
Step 8: Filtration and Storage
The extracted oil is filtered and stored in airtight, dark-colored containers to preserve its quality and aroma.
