Edible insects are recognized as a potential alternative and sustainable source of high-quality protein for the human diet. Entomophagy is highly related to negative emotions that may cause reluctance to adopt insects as food in Western countries. During human interaction, a person's facial emotional expression (FEE) may influence other people's emotional responses. A person's emotional state may affect his/her food preference and food choice. Understanding how other people's FEE would affect consumers' emotional profiles, liking, and subsequent willingness to try (WTT) and purchase intent (PI) toward insect-containing food products may help increase the acceptance of entomophagy. This study identified emotional responses toward chocolate chip cookies containing cricket protein using valence and arousal scales in order to explore the effects of other people's FEE (positive, negative, and/or sensation seeking) and to find the correlation between consumers' emotional and overall liking (OL) responses for cricket-containing chocolate chip cookies. Predicting PI for such cookies was also performed. For consumers who perceived positive emotion from other people's FEE after watching a short video clip, their emotional feeling was raised on both valence and arousal dimensions, while negative FEE stimulus imparted the opposite effects. The OL scores and emotional intensities after watching the three FEE videos were highly related to consumers' PI. Males compared to females rated the cricket-containing cookies higher on positive emotion intensity, OL, and PI. Among the three FEEs evaluated, the positive emotional stimulus would be beneficial in increasing acceptance, WTT, and PI of insect-containing foods. PRACTICAL APPLICATION: Edible insects are potentially alternative and sustainable sources of high-quality protein for the human diet. Entomophagy is highly related to negative emotions that cause reluctance to adopt insects as food in Western countries. Other people's facial emotional expressions (FEEs) may affect consumer food-evoked emotional profiles, overall liking (OL), and purchase intent (PI). For consumers who perceived positive emotion from other people's FEE, their emotional feeling was raised on both valence and arousal dimensions, and OL scores and emotion intensities were highly related to consumers' PI. Exploiting positive emotional stimuli as demonstrated in this study would be beneficial in increasing acceptance of insect-containing food.
食用昆虫被认为是人类饮食中一种潜在的、可持续的优质蛋白质替代来源。食虫与负面情绪高度相关，这可能导致西方国家的人们不愿将昆虫作为食物。在人际互动中，一个人的面部情绪表达（FEE）可能会影响其他人的情绪反应。一个人的情绪状态可能会影响其食物偏好和食物选择。了解他人的面部情绪表达如何影响消费者对含昆虫食品的情绪特征、喜好程度以及随后的尝试意愿（WTT）和购买意愿（PI），可能有助于提高对食虫的接受度。本研究使用效价和唤醒量表确定了对含有蟋蟀蛋白的巧克力曲奇饼干的情绪反应，以探究他人的面部情绪表达（积极、消极和/或寻求刺激）的影响，并找出消费者对含蟋蟀巧克力曲奇饼干的情绪反应与总体喜好（OL）之间的相关性。同时还对这类饼干的购买意愿进行了预测。对于在观看短视频片段后从他人的面部情绪表达中感知到积极情绪的消费者，他们在效价和唤醒维度上的情绪感受都有所提升，而负面的面部情绪表达刺激则产生相反的效果。观看三种面部情绪表达视频后的总体喜好得分和情绪强度与消费者的购买意愿高度相关。与女性相比，男性对含蟋蟀饼干的积极情绪强度、总体喜好程度和购买意愿的评分更高。在评估的三种面部情绪表达中，积极的情绪刺激有利于提高含昆虫食品的接受度、尝试意愿和购买意愿。实际应用：食用昆虫是人类饮食中潜在的优质蛋白质替代和可持续来源。食虫与负面情绪高度相关，这导致西方国家的人们不愿将昆虫作为食物。他人的面部情绪表达（FEE）可能会影响消费者因食物引发的情绪特征、总体喜好（OL）和购买意愿（PI）。对于从他人的面部情绪表达中感知到积极情绪的消费者，他们在效价和唤醒维度上的情绪感受会增强，总体喜好得分和情绪强度与消费者的购买意愿高度相关。利用本研究中所展示的积极情绪刺激将有利于提高对含昆虫食品的接受度。
