Verification of trans-2-hexenal sweetness by sensory evaluation. The sweetness intensities of trans-2-hexenal (5 mM) and sucrose (50 mM) were rated using a visual analog scale (VAS). Water was used as a negative control. Statistical significance among the solutions was evaluated using repeated measures one-way ANOVA, followed by the Holm–Sidak test. *** p < 0.001. Error bars indicate standard error (SE; n = 11; six males and five females, 23–49 years old).
