Galbanum SFE

Latin name :

Ferula galbaniflua // Ferula gummosa

Botanical profile :

Galbanum is a herbaceous plant of the Umbelliferae family and the genus Ferula.

Geographic origin :

Originally from Asia Minor, galbanum dedicated to F&F industries is exclusively grown in Iran

Chemotypes :

Galbanum is a shrub that grows from one to two meters high. There are two 'types' of galbanum, the soft galbanum and the hard ones. The F&F industry largely uses the ''soft '' galbanum (eg: Levant galbanum) because they have a great. The ''hard '' galbanums (ex: Persian galbanum) are cultivated mainly for the pharmaceutical industry.

In perfumery, three species of galbanum are used:
Ferula galbaniflua found in northern Iran. Leads the market
Ferula rubricaulis in southern Iran
Ferula ceratophylla in Turkistan.

Other plants of the genus Ferula are cultivated and used as a spice or for their healing benefits :
Ferula assafoetida, found in Iran and Afghanistan, used to flavour curry and sauces, and for medicinal purposes.
Ferula persica, native to Iran, sold as resin tears.

Extraction process :

Ferula gummosa needs at least three years of growth. At this time, an outgrowth is formed at the collar of the plant (collar = the part of the plant on the surface of the soil where the stem and the root system meet). This excrescence contains a milky gum. The latter is collected after multiple incisions on the collar. The harvest takes place directly on the ground, between June and September of each year and ends up with a relatively small quantity of a green-grey mixture containing numerous impurities. On arrival at the factory, the gum is warmed over a sieve to liquefy it and thus separate it from the contaminants. Its smell is then very green, crude, rough and especially very intense.
Once 'purified', the gum can be processed using the different traditional ways of extraction, including :

By hydrodistillation: obtaining Galbanum EO. The most commun (but also the most expensive) process, with a yield of around 15% from biomass. The smell is then very green, metallic, and intense. A rectification of the essential oil is possible to remove all or part of the terpenes or to work on the decoloration.
By extraction with volatile solvents: obtaining Galbanum Resinoid by passing through the stage of Galbanum Concrete and, although this is very rare, going until obtaining Galbanum Absolute.
By CO2 extraction: obtaining Galbanum SFE with a more powdery, less crude/hard smell. ''
