摘要 食用食物时的美味感主要是通过对食物本身提取的感官信息（如味觉和嗅觉）的感知而产生的。然而，环境因素可能会改变美味的感觉。在本研究中，我们研究了视听环境条件如何影响吃甜食时的美味感。分别在茶室和建筑工作的虚拟场景下记录健康参与者头皮额叶区域的脑电图（EEG）。参与者被要求在录音后对美味进行评分。根据脑电图进行频率分析。就餐过程中，茶室场景和施工场景的β频段占用率存在显着差异，而其他频段则没有差异。相比之下，在没有食物的情况下，两个不同场景在各自频段的占用率没有差异。对于吃甜食时的美味感，所有参与者在茶室场景下的评分都高于在建筑工地场景下的得分。有趣的是，β频段的占用率与美味评分之间存在正相关关系。这些发现表明，舒适的视听环境对于增加吃甜食时的美味感起着重要作用，其中β频率节律可能与产生全面的美味感有关。
Abstract Feelings of deliciousness during having foods are mainly produced by perceptions of sensory information extracted from foods themselves, such as taste and olfaction. However, environmental factors might modify the feeling of deliciousness. In the present study, we investigated how the condition of audio-visual environments affects the feeling of deliciousness during having sweet foods. Electroencephalograms (EEGs) were recorded from the frontal region of the scalp of healthy participants under virtual scenes of tearoom and construction work, respectively. The participants were asked to rate deliciousness after the recordings. Frequency analyses were performed from the EEGs. During having the foods, occupancy rates of beta frequency band between tearoom scenes and construction work scenes were markedly different, but not in other frequency bands. During having no food, in contrast, there was no difference of occupancy rates in respective frequency bands between the two different scenes. With regard to deliciousness during having sweet foods, all participants rated high scores under the scenes of tearoom than those under the scenes of construction work. Interestingly, there is a positive correlation between occupancy rates of beta frequency band and scores of deliciousness. These findings suggest that comfortable audio-visual environments play an important role in increasing the feeling of deliciousness during having sweet foods, in which beta frequency rhythms may be concerned with producing comprehensive feelings of deliciousness.
