Investigating the temporality of binary taste interactions in blends of sweeteners and citric acid in solution

This study investigated sweet–sour taste interactions in novel sweeteners using a 3 × 2 factorial design consisting of Sweetening System (three levels: sucrose; d-allulose; and blend d-allulose Monk fruit extract) Acidity (two with or without citric acid). 110 untrained Chinese subjects participated the temporal check-all-that-apply (TCATA) method. Mixed-model ANOVA was conducted to investigate effect System, Acidity, their on fractional Area Under Curve within three 20 s time intervals (attack, evolution, finish). Treatments were compared Dunnett's test sucrose as control. Citric acid suppressed sweet both more than extract throughout attack evolution intervals. finding confirmed by significant interaction between for taste. Sour not affected differently different Systems difference sweetener concentration. Practical Applications showed that could be altered have similar profile most evaluation time. emphasizes importance only conducting evaluations aqueous solutions but also considering studies complex matrices choice methodology used measure sensory profile.
