The Pungent Powerhouses of the Cabbage Family
Unleashing the Heat
When it comes to adding a kick to our meals, two condiments stand out from the rest: horseradish and wasabi. But what makes these pungent powerhouses so potent?
The Roots of the Matter
Both horseradish and wasabi are derived from the roots of plants in the cabbage family: Armoracia rusticana and Wasabia japonica, respectively. It’s the cells within these roots that hold the secret to their intense flavor and aroma.
A Chemical Reaction
When these cells are ruptured – whether through chopping, chewing, or other means – they release a compound called allyl isothiocyanate. This chemical is not only responsible for the pungent taste, but also the irritating sensation in our nose and eyes. According to T. Page Owen, PhD, chair of the Connecticut College Botany Department, this reaction is what sets off the chain of events that leaves us reaching for a glass of milk.
The Science Behind the Burn
As we consume wasabi or horseradish, the allyl isothiocyanate vapors travel through the back of the mouth and up into the nasal cavity. This triggers a nerve response in the nose and sinuses, explains Dr. Dawn Chapman, project leader for sensory research at the National Food Laboratory. The result? The familiar nose-tingling burn that leaves us breathless.
A Sensory Experience
So the next time you reach for the wasabi or horseradish, remember the complex science behind the heat. It’s not just a matter of taste – it’s a sensory experience that awakens our senses and leaves us wanting more.
