    Health claim effects on consumer acceptability, emotional responses, and purchase intent of protein bars
    (Elsevier B.V., 2022-03-11) Thakur M; Sharma C; Mehta A; Torrico DD
    Consumers are seeking product's claims to make their daily food purchase decisions more informed. In this context, health claims can communicate to consumers about nutrient-specific health benefits. The objective of this research was to study the effect of health claims, in textual form, on consumers' acceptability, emotional responses, and purchase decisions regarding protein bars. For this study, four protein bars were selected by a focus group (N = 6) based on acceptability. A total of N = 80 participants evaluated the pre-selected protein bars in two different tasting sessions [(1) Blind, where no information was provided, and (2) Informed, where health-related information of protein bars was provided]. Participants rated their liking for different sensory attributes (appearance, aroma, taste, texture, sweetness, bitterness, and aftertaste) and overall liking using a 9-point hedonic scale. Check-all-that-apply (CATA) was used to study emotions and 22 terms related to sensory attributes of the protein bar. There was a non-significant increase in the purchase intent for three out of four samples in session 2 but it was found to be high for the sample associated with positive emotions. Overall, this study showed that taste overpowered the health claims (expressed in textual form) on the acceptability. There were, however, slight effects of the health claims on the elicited emotions of consumers towards the protein bars.

    Self-Reported Emotions and Facial Expressions on Consumer Acceptability: A Study Using Energy Drinks
    (MDPI (Basel, Switzerland), 2021-02) Mehta A; Sharma C; Kanala M; Thakur M; Harrison R; Torrico DD; Byrne DV
    Emotional responses elicited by foods are of great interest for new product developers and marketing professionals, as consumer acceptance proved to be linked to the emotions generated by the product in the consumers. An emotional measurement is generally considered an appropriate tool to differentiate between the products of similar nutritional value, flavour, liking and packaging. Novel methods used to measure emotions include self-reporting verbal and visual measurements, and facial expression techniques. This study aimed to evaluate the explicit and implicit emotional response elicited during the tasting of two different brands (A and B) of energy drinks. The explicit response of consumers was assessed using liking (nine-point hedonic scale), and emotions (EsSense Profile®-Check-All-That-Apply questionnaire), and implicit emotional responses were evaluated by studying facial expressions using the Affectiva Affdex® software. The familiarity of the product and purchase intent were also assessed during the study. The hedonic rating shows a significant difference in liking between the two brands of energy drink during the tasting session. For the explicit emotional responses, participants elicited more positive emotions than the negative emotions for both energy drinks. However, participants expressed "happy", "active" and "eager" emotions more frequently for energy drink A. On the other hand, the implicit emotional responses through facial expressions indicated a high level of involvement of the participants with energy drink B as compared to energy drink A. The study showed that overall liking and the explicit and implicit emotional measurements are weakly to moderately correlated.
