Concept:
Essential oils and fragrances are extracted using various physical and chemical methods.
• Delicate flowers like Jasmine or Tuberose cannot withstand steam distillation.
• Their fragrance continues to be produced even after the flowers are picked.
• Cold fat absorption is used to capture these volatile scents.
Step 1: Defining Enfleurage.
Enfleurage is a French technique developed in the 18th century.
It utilizes odorless animal or vegetable fats that are spread onto glass plates.
Step 2: The extraction process.
Fresh flower petals are placed on the fat layer and left for several days.
The fat absorbs the essential oils released by the flowers.
Spent flowers are replaced with fresh ones until the fat is saturated with scent.
Step 3: Final recovery.
The resulting scented fat is called a "pomade."
The pure essential oil is later extracted from the fat using alcohol.
