Abstract
Liking for 4 levels of sucrose solution (2.5%, 5.0%, 10.0%, 20.0%) and 3 kinds of sugar solution having different taste qualities of sweetness were investigated using sensory evaluation in junior high school students and adults (290 subjects).The questionnaire survey including affection, cognition, liking and consumption of sweets was conducted in the same subjects and the relation between response and liking for sugar solutions was examined.
Analysis of variance showed that age was the important factor influencing the liking for sucrose concentration.Junior high school students and elderly adults (60+years) were inclined to like higher sucrose concentrations and not to like lower sucrose concentration. The young middle-aged subjects (30-39years) liked low sucrose concentration and did not like high sucrose concentration compared to the distribution of liking in other age groups.It was considered that there was a turning point in sweetness preference in this middle age-group.Females liked 2.5% sucrose solution better than males.Affection for sweets influenced the choice of sucrose concentration, while cognition of sweets had no effect on the liking for sucrose concentration.The degree of liking or eating sweets and the preference of intensity in seasoning also related to the choice of sucrose concentration. Liking for sugar solutions with different taste qualities did not relate to age or sex.
