Excretion and perception of a characteristic odor in urine after asparagus ingestion: a psychophysical and genetic study.

Chemical senses - 1 Jan 2011

Pelchat Marcia Levin, Bykowski Cathy, Duke Fujiko F, Reed Danielle R

Abstract excerpt

The urine of people who have recently eaten asparagus has a sulfurous odor, which is distinct and similar to cooked cabbage. Using a 2-alternative forced-choice procedure, we examined individual differences in both the production of the odorants and the perception of this asparagus odor in urine....
