Abstract
The goal of this preliminary study was to examine the effect of participants’ sexes on the temporal sequence of dominant sensations elicited by fruit-flavored teas. Twelve healthy young adults were assigned to male (n = 6) and female (n = 6) groups. Both groups were evaluated for four sensations using four fruit-flavored teas with 0.05 M sucrose using the temporal dominance of sensations (TDS) method. Only two sensations, sweetness and fruitiness, were consistently reported in the two groups. The male group first reported fruitiness and then sweetness as the dominant sensation following ingestion of the samples. Conversely, the female group reported these two dominant sensations in the reverse order. Significant dominant durations between the two sensations largely varied among the samples in both groups. These results suggest that there are sex-based differences in the temporal sequence of dominant sensations elicited by fruit-flavored teas as evaluated by the TDS method.
Highlights
Investigation of interactions between taste and smell is a keystone for understanding of flavor perception, since the term “flavor” as a sensation resulting from interactions of taste, smell, and trigeminal sensations [1] [2]

Summary
Investigation of interactions between taste and smell is a keystone for understanding of flavor perception, since the term “flavor” as a sensation resulting from interactions of taste, smell (aroma), and trigeminal sensations [1] [2]. Temporal dominance of sensations (TDS) method has been used to understand temporal sequence of the perception of sensory attributes of drinks and foods [5]. Di Monaco and colleagues examined the temporal aspects of the enhancement of six sensations, including sweetness and fruitiness (strawberry flavor) in four model beverages using TDS [6]. A survey analyzed the saccharides in 42 sweet snacks and beverages in Japan and reported that three sweet teas contained an average of 0.05 M to 0.18 M sucrose [7]. The sex of study participants considerably affects various sensory functions [8], no previous studies have considered the participants’ sex when examining temporal aspects of these flavor enhancements [5] [9] [10] [11]. We examined the effect of participants’ sex on temporal sequence of flavor sensations elicited by fruit-flavored teas with an average level of sugar (0.05 M) preliminarily
