Abstract
A vanilla flavor composition is produced by vanilla-plant callus cells suspended in tissue culture, under conditions which promote secretion of vanilla flavor components into the culture medium. The flavor components may be separated from the medium by adsorption resins. Also disclosed are methods for preparing callus cells capable of secreting flavor components in tissue culture, and callus cells produced thereby.
