Zanimljivosti
Allyl isothiocyanate, mustard's pungent molecule, activates the exact same receptor (TRPA1) as tear gas, wasabi, and the Carolina Reaper. The plant produces it as a chemical weapon against herbivores — the myrosinase-sinigrin 'bomb' only detonates when the seed is damaged, a system called a 'chemical binary weapon.'
Dobijanje i hemija
Način dobijanja
Mustard essential oil (allyl isothiocyanate) is obtained by steam distillation of crushed Brassica nigra or B. juncea seeds after enzymatic activation. The oil is extremely pungent and toxic at concentration — it is a powerful lachrymator. Handled only by specialists. White mustard (Sinapis alba) produces a milder oil with different chemistry.

U parfemima
Mustard seed is an extreme spice note rarely used in perfumery. The isothiocyanate is too pungent and irritating for most applications. At extreme dilution, it can provide a sharp, horseradish-like accent in dark-spicy and provocative compositions. Built from allyl isothiocyanate (at extreme dilution) or approximated using sharp-pungent synthetics.
