Abstract
ABSTRACT Sweetness and fruitiness of equisweet solutions of aspartame (APM), an aspartame + acesulfame‐K blend (APM/AK) or sucrose were evaluated in binary (BIN) (sweetener and orange flavor) and tertiary (TER) (BIN and citric acid) systems by time‐intensity (TI) methodology. Sweetener solutions adjusted to the viscosity of sucrose (APM* and APM/AK*) showed small inconsistent differences from their unthickened counterparts. In BIN systems, APM and APM* had the longest duration (DUR) of sweetness and fruitiness. In TER systems, APM* increased maximum intensity (MAX) and DUR of fruitness and S decreased sourness MAX and DUR relative to APM and APM/AK blends. Fruitiness MAX was perceived later than sweetness, whereas sweetness DUR persisted longer than fruitiness.
