摘要： A process has been developed for production of a food flavoring compound maltol which comprises (a) extracting the dried and pulverized leaves of the plants belonging to the genus Abies with an alcohol at 20-40° C. and concentrating the solvent to obtain an alcoholic extract, (b) adsorbing the alcoholic extract with an adsorbent and drying the adsorbed material at a temperature ranging between 20-50° C., (d) partitioning of the adsorbed material between selected solvents consisting of aliphatic hydrocarbon and chlorinated solvent successively, (d) concentrating the chlorinated solvent to a residue and crystallizing it from a suitable organic solvent or mixtures of such solvents to get pure maltol.
