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 insectcontaining 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.Abbreviations: AfterV, after watching facial emotional expression video before tasting the cookie; CATA, check-all-that-apply; FEE, facial emotional expressions; ICookie, cookie containing cricket protein; ICookie_BEI, informing consumers of benefits of entomophagy; ICookie_Info, informing consumers that cookie contained cricket protein; NICookie, cookie without cricket protein; OL, overall liking; PI, purchase intent; SAM, Self-Assessment Manikin; SSK, sensation-seeking; V n1 , video of negative facial emotional expressions; V n2 , video of negative facial emotional expressions when consuming cookie; V nr , video of negative facial emotional expressions when consuming cookie and participants were informed that cookies in the video contained cricket protein; V p1 , video of positive facial emotional expressions; V p2 , video of positive facial emotional expressions when consuming cookie; V pr , video of positive facial emotional expressions when consuming cookie and participants were informed that cookies in the video contained cricket protein; V s1 , video of sensation-seeking facial emotional expressions; V s2 , video of sensation-seeking facial emotional expressions when consuming cookie; V sr , video of sensation-seeking facial emotional expressions when consuming cookie and participants were informed that cookies in ...
