Application of zeolites in the downstream processing of the character impact compound 2,5-dimethyl-4-hydroxy-furan-3-one (Furaneol)

The purpose and scope of this article is to introduce capable zeolites into downstream processing of natural compounds, especially flavour compounds l ike 2,5-dimethyl-4-hydroxy-3 (2H)-furan-3-one (Furaneol(R)*). The synthesis and the recovery of Furaneol from L-rhamnose are presented. Therefore adso rption isotherms of the zeolites ZSM5 and DAY with varying modules have bee n determined and adsorption experiments using model and reaction mixtures o f Furaneol synthesis were performed and will be discussed.
