Abstract
SummaryVarious monomeric and polymerized cyclodextrins were investigated for their potential application in decaffeination. Treatment of aqueous caffeine solutions with monomeric gammacyclodextrin resulted in a significant reduction in the caffeine content of solutions over a wide range of caffeine concentration. Polymerized beta- and gamma-cyclodextrins were also demonstrated to be effective in removing caffeine by either a batch or column decaffeination process. Under the as-yet unoptimized process conditions, caffeine reduction of around 80% could readily be achieved. The process was applicable to caffeine-containing beverages (including coffee, tea, cocoa, and cola drinks) as well as theobromine-containing beverages (such as cocoa).
