Abstract As a result of sensory specific satiation, liking of a food decreases with its consumption. However, food liking is most often assessed once for a small quantity of products. In adults, new techniques have been developed to record changes in liking during consumption of a full portion of food. However, these temporal techniques have never been applied in children so far. The first objective was to develop a new method for hedonic assessment in a dynamic manner with school-aged children in a naturalistic setting of consumption at school. The second objective was to compare the regular liking evaluation (static liking) with the dynamic one (6 successive assessments during consumption of a full portion), using a linear scale containing 7 labels. To do so, 48 8- to 10-year-old children (19 boys and 29 girls) were enrolled in the study. Children were invited to take part in four snacks (2 static liking assessments and 2 dynamic liking assessments, in alternation) involving tasting fruit purees. Before and after each snack, the children also evaluated how hungry they were on a new 5-point unstructured scale. The results showed that the temporal measure was sensitive enough to capture a decrease in liking during the consumption of a full portion. In addition, the average liking score assessed with the static method was similar to the average liking score of the 1st evaluation with the dynamic method. Moreover, the decrease in liking during consumption was significantly linked to the decrease in the level of hunger. In conclusion, this new method appears to be suitable for measuring dynamic liking with school-aged children.

一种测量 8 至 10 岁儿童食物消费过程中喜好演变的动态方法

摘要 由于感官特定的饱足感，对食物的喜好会随着食用而减少。然而，食物喜好通常只针对少量产品进行一次评估。在成年人中，已经开发出新技术来记录食用全部食物期间的喜好变化。然而，到目前为止，这些时间技术从未应用于儿童。第一个目标是开发一种新方法，以动态方式对学龄儿童在学校自然消费环境中进行享乐评估。第二个目标是使用包含 7 个标签的线性量表，将常规喜好评估（静态喜好）与动态喜好评估（在整个部分消费期间进行 6 次连续评估）进行比较。为此，48 名 8 至 10 岁的儿童（19 名男孩和 29 名女孩）参加了这项研究。儿童被邀请参加包括品尝果泥在内的四项小吃（交替进行 2 项静态喜好评估和 2 项动态喜好评估）。在每次吃零食之前和之后，孩子们还评估了他们在新的 5 分非结构化量表上的饥饿程度。结果表明，时间测量足够敏感，可以捕捉到在整个部分消费期间喜好的减少。此外，静态方法评估的平均喜好分数与动态方法第一次评估的平均喜好分数相似。此外，消费期间喜好的下降与饥饿程度的下降显着相关。总之，这种新方法似乎适用于测量学龄儿童的动态喜好。
