Abstract
A flavorant agent is prepared by incubating a medium of baker's yeast, elemental sulfur and a reducing sugar to obtain a reaction medium from which hydrogen sulfide gas evolves and then the reaction medium is treated with heat to obtain the flavorant agent. A further flavorant agent is obtained by separating the supernatant of the reaction medium from reaction medium residue, and the reaction medium or supernatant may be mixed with a flavor precursor material and heated to obtain a flavorant composition.
