Detecting thiamine in beer.
OBJECTIVE
To ascertain whether thiamine HCl could be detected in beer using a double-blind triangular taste test.


METHODS
Three 100 ml samples of beer to which 10 or 0 mg of thiamine were added were presented in counterbalanced order to 49 volunteers. Subjects consumed and rated each sample separately for taste and appearance and chose which beer was different.


RESULTS
Thiamine-enriched beer could not be reliably distinguished from normal beer. However, a significant perceptual taste difference was found, with participants rating thiamine-fortified beer as more bitter than normal beer.


CONCLUSIONS
Thiamine was found to alter the perception of bitterness of beer, but thiamine-fortified beer could not be reliably distinguished from normal beer.
