ABSTRACT:
A process for recovering .gamma.-pyrones such as maltol and/or ethyl maltol from solutions containing other substances involves an elution chromatographic treatment using a stationary phase that separates the .gamma.-pyrones from the other substances by means of ion exclusion, size exclusion, hydrophobic partitioning, and/or chelation. In one embodiment, a cation exchange resin such as sulfonated divinyl benzene-cross-linked polystyrene is employed, and the .gamma.-pyrones obtained can be further purified by crystallization from water and/or other means.
