The pungency of the [[Mustard (condiment)|condiment mustard]] results when ground mustard seeds are mixed with [[water]], [[vinegar]], or other liquid (or even when chewed). Under these conditions, a chemical reaction between the [[enzyme]] [[myrosinase]] and a [[glucosinolate]] known as [[sinigrin]] from the seeds of black mustard (''[[Brassica nigra]]'') or brown Indian mustard (''[[Brassica juncea]]'') produces [[allyl isothiocyanate]]. By [[distillation]] one can produce a very sharp-tasting [[essential oil]], sometimes called ''volatile oil of mustard'', containing more than 92% allyl isothiocyanate. The pungency of allyl isothiocyanate is due to the activation of the [[TRPA1]] ion channel in sensory neurons. White mustard (''[[Brassica hirta]]'') does not yield ''allyl'' isothiocyanate, but the milder [[4-Hydroxybenzyl isothiocyanate]] degraded from [[sinalbin]] rather than [[sinigrin]].
