TIME-INTENSITY PARAMETERS OF SELECTED CARBOHYDRATE AND HIGH POTENCY SWEETENERS

Time-intensity (TI) sweetness curves were generated and ten TI paramet ers were determined for selected carbohydrate and high potency sweeten ers. Samples were evaluated by trained panelists at 5% sucrose equival ency (SEV) in water for sucralose, sucrose, fructose, aspartame, cycla mate, acesulfame-K and saccharin and at 9% SEV in water and a buffered model beverage system for sucralose, sucrose, fructose, aspartame and cyclamate. When compared within each system, differences in temporal properties appeared to be concentration and media dependent. No differ ences in onset characteristics were observed among equisweet groups. A ftertaste characteristics differed among sweeteners only at 9% SEV in water where high potency sweeteners tended to have somewhat longer aft ertaste than nutritive sweeteners.
