Chronotype refers to an individual's tendency to engage in activities either earlier or later, in alignment with the biological rhythm of their body and its interaction with the environmental cycle. Chronotypes influence food preferences and meal timing, yet most studies rely solely on questionnaires without integrating real-time tasting data. To address this gap, we developed and validated a method to measure sensory perception and examine its variations throughout the day in alignment with circadian rhythms. Fifty-two university students completed the Munich Chronotype Questionnaire and, over four days within a week, they participated in sensory evaluations using a web-based questionnaire. At four daily time slots (morning, midday, afternoon, evening), participants tasted candies and assessed some sensory attributes-sweetness, sourness, bitterness, freshness, and overall flavor-using the Rate-All-That-Apply method. Before each evaluation, they also reported their level of hunger, thirst, tiredness, and willingness to complete the task. Reminders were sent via pre-programmed messages to ensure adherence to the schedule. The results demonstrate the feasibility of the method, with low attrition rates and consistent participant motivation over the study period. Sensory perception was found to vary across the day and in relation to chronotype, highlighting the method's potential for advancing research in sensory chrononutrition.•A web-based questionnaire including tasting was developed to assess sensory perception at different times of the day over four days.•Perception was analyzed in relation to chronotype.•Face validity was confirmed, as significant variations based on chronotypes were observed.
昼夜节律类型指的是个体倾向于在更早或更晚的时间进行活动，这与他们身体的生物节律及其与环境周期的相互作用相一致。昼夜节律类型会影响食物偏好和用餐时间，但大多数研究仅依赖问卷调查，而没有整合实时味觉数据。为了弥补这一差距，我们开发并验证了一种方法，用于测量感官感知，并研究其在一天中与昼夜节律一致的变化情况。52名大学生完成了慕尼黑昼夜节律类型问卷，并且在一周内的四天里，他们通过网络问卷参与了感官评估。在每天的四个时间段（上午、中午、下午、晚上），参与者品尝糖果，并使用“全部适用”评分法评估一些感官属性——甜度、酸度、苦味、新鲜度和整体风味。在每次评估之前，他们还报告了自己的饥饿、口渴、疲劳程度以及完成任务的意愿。通过预编程信息发送提醒，以确保遵守时间表。结果证明了该方法的可行性，在研究期间损耗率较低，参与者积极性一致。研究发现，感官感知在一天中以及与昼夜节律类型相关的情况下会有所不同，这突出了该方法在推进感官时间营养学研究方面的潜力。
•开发了一个包括味觉测试的网络问卷，以评估四天内一天中不同时间的感官感知。
•对感知与昼夜节律类型的关系进行了分析。
•确认了表面效度，因为观察到基于昼夜节律类型的显著差异。
