neutralizing odor with zwaardemaker pairs

neutralizing odor with zwaardemaker pairs

Henry Zwaardemaker was a Dutch Physiologist who invented the olfactometer in 1888

The olfactometer is still less sensitive than the human nose today

Zwaardemaker also discovered that certain pleasant aromas blocked the perception of specific foul odors, effectively neutralizing their scent

These pleasant aromas and the corresponding foul odor they each blocked were termed zwaardemaker conjugates or zwaardemaker pairs and are listed here
