Flavorist reconstruction formula for asafoetida aroma

Below is a typical flavor-chemist reconstruction approach for the aroma of Ferula assa-foetida (asafoetida). The profile is dominated by allylic and sec-butyl sulfur compounds that produce the characteristic garlic–onion–sulfur savory odor.

Because the real spice is extremely potent, reconstructions are usually prepared as very dilute stock solutions (0.1–1% in solvent) before evaluation.
