How to Extract Scent from Jasmine Flowers?

Extracting the exquisite scent from jasmine flowers is traditionally achieved through a delicate process called effleurage.

The captivating aroma of jasmine flowers, particularly used to create products like Jasmine Absolute, is traditionally captured using a specific extraction method designed for their fragile petals.

Traditional Effleurage Method

Based on historical techniques, the primary way to extract the scent from fresh jasmine flowers is effleurage. This method is particularly suited for flowers like jasmine that continue to release fragrance after being picked, unlike those from which essential oils can be distilled directly.

The process involves:

1. Preparation: Spreading fresh jasmine petals thinly over a layer of cold fat (traditionally purified animal fat, though vegetable fats are used in modern variations). The fat is spread on glass plates held in wooden frames (known as chassis).
2. Absorption: The frames are stacked, and the fresh petals are left on the fat layer for many hours. During this time, the aromatic oil from the petals is absorbed into the fat.
3. Replenishment: The spent petals are carefully removed and replaced with fresh ones. This step is repeated periodically over several days or even weeks until the fat becomes saturated with the jasmine fragrance.
4. Extraction from Fat: Once the fat is fully saturated (becoming what's known as a pomade), the fragrant compounds are extracted from the fat using a solvent, typically alcohol.
5. Concentration: The alcohol is then evaporated, leaving behind the highly concentrated aromatic material known as Jasmine Absolute.

Reference Information Included: Jasmine Absolute was traditionally extracted through a method of effleurage, in which fresh petals were spread over a layer of cold fat and left for many hours until their oil had been absorbed. Petals would have to be periodically changed to saturate the fat with their aromatic essence.

This labor-intensive process yields a precious and intensely fragrant extract that captures the true scent profile of fresh jasmine flowers.
