文摘
Montmorillonite (MMT) selectively adsorbed caffeine in various tea extracts. MMT showed higher selectivity for caffeine as compared with activated carbon. MMT adsorbed caffeine quickly, regardless of the temperature or pH examined. The taste of the tea extract decaffeinated by MMT changed very little.
