Abstract
Fermentation experiments have indicated that ethyl carbamate was not formed during fermentation, even in the presence of urea, ammonium phosphate, or amino-acid-containing yeast foods at 12 times allowable levels. Heating of end fermentation broths, however, led to ethyl carbamate formation, but only from fermentation supernatants where urea was used.
