Abstract
Consumer perception of foods processed by emerging technologies has been scarcely studied. This study aimed to evaluate the perception of vegan and non-vegan consumers regarding probiotic almond-fermented beverages processed by ultrasound using the packaging of the products (pasteurized/conventional, processed by ultrasound, and processed by ultrasound with a claim on the label). A "Check All That Apply" test with emojis and the Food Technology Neophobia scale were used. The "processed by ultrasound" information did not impact the purchase intention and the perception of healthiness, safety, nutrition, environmental impact, flavor, texture, and price of the products. The claim inclusion increased the perceived acceptability and purchase intention and improved the emotional profile. The vegan consumers showed a more positive perception of ultrasound processing, resulting in increased perceived acceptability, higher citation frequency of positive emoji, and lower sums for the neophobia scale. Vegan and non-vegan consumers agreed that the most important attributes for consumer acceptance are almond aroma, flavor, and consistency. In conclusion, the "processed by ultrasound" information did not negatively impact the acceptability and emotional profile of probiotic almond-fermented beverages, and using a claim on the label may improve consumer perception of the products.

Kelly B, Boyland E, Tatlow-Golden M, Christiansen P. Testing a conceptual Hierarchy of Effects model of food marketing exposure and associations with children and adolescents' diet-related outcomes. Public Health Nutr 2023; 27:e10. [PMID: 38058182 PMCID: PMC10830363 DOI: 10.1017/s1368980023002616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 10/29/2023] [Accepted: 11/23/2023] [Indexed: 12/08/2023]
Abstract
OBJECTIVE Children's exposure to unhealthy food marketing contributes to poor diets by influencing the foods that children like, request, buy and consume. This study aimed to use confirmatory mediational analyses to test a hypothetical model of marketing effects, to better understand the mechanisms behind food marketing's impacts on children. DESIGN Children responded to a cross-sectional online survey about their attitudes towards, and purchase and consumption behaviours of, ten frequently promoted food/beverage brands and their media use. Structural equation modelling tested a priori potential pathways for the effects of food marketing exposure on children's diets. PARTICIPANTS 10-16-year-old children (n 400). SETTING Australia. RESULTS There was a significant positive correlation between children's commercial screen media use and their attitudes towards brands (related to perceived social norms) and their brand purchasing behaviours, including their own purchases and requests to parents. The use of strategies to avoid advertising in commercial screen media reduced but did not remove the association between media use and brand purchases. Other brand exposures (on clothing, outdoor advertising, sponsorships) had a positive association with children's perceived social norms about brands and their brand purchases and requests. Non-commercial screen media use was not associated with any brand-related outcomes. CONCLUSIONS Commercial screen media use and other brand exposures were strongly positively associated with children's perceptions and purchasing behaviours of frequently marketed food/beverages. Regulations to restrict children's exposures to food marketing on-screen and through other media are required to reduce the effect of marketing exposure on children's food purchasing behaviours.

Abstract
This narrative review revises the scientific evidence of recent years on healthy eating in children and adolescents, making sense of promising avenues of action, from a food system perspective. A conceptual framework is provided to better understand how eating habits of children and adolescents are shaped to identify key multisectoral approaches that should be implemented to promote healthier diets. The following influencing factors are discussed: individual factors (physiological and psychological factors, food preferences and food literacy competencies), factors within the personal and socio-cultural food environments, external food environments, and the supply chain. In each section, the main barriers to healthy eating are briefly discussed focussing on how to overcome them. Finally, a discussion with recommendations of actions is provided, anchored in scientific knowledge, and transferable to the general public, industry, and policymakers. We highlight that multidisciplinary approaches are not enough, a systems approach, with a truly holistic view, is needed. Apart from introducing systemic changes, a variety of interventions can be implemented at different levels to foster healthier diets in children through fostering healthier and more sustainable food environments, facilitating pleasurable sensory experiences, increasing their food literacy, and enhancing their agency by empowering them to make better food related decisions. Acknowledging children as unique individuals is required, through interpersonal interactions, as well as their role in their environments. Actions should aim to enable children and adolescents as active participants within sustainable food systems, to support healthier dietary behaviours that can be sustained throughout life, impacting health at a societal level.

Foods 2023; 12:foods12112250. [PMID: 37297493 DOI: 10.3390/foods12112250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 05/11/2023] [Accepted: 05/31/2023] [Indexed: 06/12/2023] Open
Abstract
In 2020, a single-response-based, valence × arousal circumplex-inspired emotion questionnaire (CEQ) was developed. Using a between-participants design, previous studies have found that a multiple response (MR) condition better discriminated test samples (e.g., written food names) based on their evoked emotions than a single response (SR) condition. This research, comprising Studies 1 and 2, aimed to determine the effect of response conditions (i.e., SR vs. MR) on emotional responses to food image samples, using a within-participants design. In Study 1, 105 Korean participants were asked to select a pair of emotion terms (i.e., SR condition) or select all pairs representing their evoked emotions (i.e., MR condition) from a list of 12 pairs of emotion terms of the CEQ, in response to the 14 food images. Both SR and MR conditions were tested within a remote (online) session. To minimize both a potential carry-over effect of the "within-participants design" and an influence of environmental factors in the remote testing, Study 2 asked 64 U.S. participants to do so over two separated sessions on two different days in a controlled laboratory setting. In both Studies 1 and 2, participants selected the CEQ's emotion-term pairs in the MR condition more frequently than in the SR condition, leading to the MR condition's higher capacity to discriminate test samples. While the configurations of the correspondence analysis biplots drawn in the SR and MR conditions were similar, those in the MR condition were more likely to be similar to the configurations of the principal component analysis biplots drawn from the ratings of valence and arousal for food image samples. In conclusion, this study provides robust empirical evidence that the MR condition can perform better in capturing sample differences in food-evoked emotions, while the SR condition is also effective in characterizing emotional profiles of test samples. Our findings will provide practical insights to sensory professionals, enabling them to effectively leverage the CEQ or its variants when measuring food-evoked emotions.

Correlation of Taste Components with Consumer Preferences and Emotions in Chinese Mitten Crabs ( Eriocheir sinensis): The Use of Artificial Neural Network Model. Foods 2022; 11:foods11244106. [PMID: 36553846 PMCID: PMC9777666 DOI: 10.3390/foods11244106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 12/05/2022] [Accepted: 12/10/2022] [Indexed: 12/24/2022] Open
Abstract
This study took a consumer sensory perspective to investigate the relationship between taste components and consumers’ preferences and emotions. Abdomen meat (M), hepatopancreas (H), and gonads (G) of Chinese mitten crabs, one from Chongming, the Jianghai 21 variety (C-JH), and two from Taixing, the Jianghai 21 (T-JH) and Yangtze II varieties (T-CJ), were used to evaluate flavor quality. The results indicated that in the abdomen meat, differences in taste components were mainly shown in the content of sweet amino acids, bitter amino acids, K+, and Ca2+; M-C-JH had the highest EUC value of 9.01 g/100 g. In the hepatopancreas, bitter amino acids were all significantly higher in H-C-JH (569.52 mg/100 g) than in the other groups (p < 0.05). In the gonads, the umami amino acid content was significantly higher in G-T-JH than in the other groups (p < 0.05) (EUC values: G-T-JH > G-C-JH > G-T-CJ). Consumer sensory responses showed that different edible parts of the crab evoked different emotions, with crab meat being closely associated with positive emotions and more complex emotional expressions for the hepatopancreas and gonads. In comparison, consumers were more emotionally positive when consuming Yangtze II crab. H-C-JH evoked negative emotions due to high bitter taste intensities. Multifactor analysis (MFA) showed arginine, alanine, glycine, proline, K+, and Ca2+ were found to have a positive correlation with consumer preference; an artificial neural network model with three neurons was built with good correlation (R2 = 0.98). This study can provide a theoretical foundation for the breeding of Chinese mitten crabs, new insights into the river crab industry, and the consumer market.

J Food Sci 2022; 88:106-121. [PMID: 36413025 DOI: 10.1111/1750-3841.16374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 09/30/2022] [Accepted: 10/12/2022] [Indexed: 11/23/2022]
Abstract
In line with the increasing popularity of emoji, the need for methodological research into these pictorial representations of emotion remains. The present research contributes to this goal by continuing to establish the meaning of emoji and exploring these according to between-country and interpersonal differences. The emoji (n = 12) were selected to span the valence × arousal emotion space, and the PAD model (Pleasure-Arousal-Dominance) was used to establish emoji meaning for the three dimensions, operationalized as measurement on 6 × 3 semantic differentials. Participants in the main study came from three countries-Germany, Singapore, and Malaysia (n = 2465), and a supplementary study included the United Kingdom and New Zealand (n = 600) (subset of four emoji). The results confirmed that emoji meanings according to the PAD model were largely similar between countries (albeit not identical). There were multiple minor significant differences for individual emoji, and where these existed, they often related to the dimension of Arousal, prompting a need for further investigation. Interpersonal differences were examined for gender (men and women), age group (18-45 and 46-69 years old), and frequency of emoji use. Again, significant differences were smaller rather than larger and supported the notion that emoji are generally applicable for multicountry research. However, caution regarding the participants who use emoji infrequently may be warranted. PRACTICAL APPLICATION: The findings from this research will help academics and practitioners who are interested in using emoji for sensory and consumer research (or are already doing so) with more robust interpretations of their findings. For a set of 12 emoji that provide broad coverage of the valence × arousal emotional space, meanings are provided on the three dimensions of the PAD model. The data is collected in five countries and contributes to increased confidence that emoji meanings are by and large similar in these countries.

Abstract
For deeper insight into beef consumer experiences during consumption, sensory descriptions seem to be insufficient, and exploration of emotions evoked by this product are required. In this context, the present study aimed to evaluate the emotions evoked by beef consumption in different contexts. To that end, this work was structured as follows: 1) Emotional vocabulary development; 2) Selection of beef cuts; and 3) Emotional profiling of beef cuts. The emotional vocabulary was useful for characterizing emotions evoked by two beef cuts with different sensory profiles, in different contexts, considering a within-subjects design. Rump cap samples showed the highest liking and were associated with positive emotions, while outside flat samples were less liked and characterized by negative emotions. The evoked context had no effect on hedonic and emotional intensities, but increased the number of emotions elicited by consumers. The correlation of sensory, hedonic and emotional information indicated that tenderness and internal color of beef were correlated with positive emotions and higher liking scores.

Abstract
This study aimed to develop and validate a product-specific emoji list and use this list to analyse children's emotional responses associated with the consumption of probiotic fermented milks prepared with different probiotic strains. Furthermore, the overall liking of the products was studied during a sensory test. Six formulations were studied: Bifidobacterium BB12 (BB), Lactobacillus acidophilus L3 (LA3), Lactobacillus acidophilus LA 05 (LA5), Lactobacillus delbrueckii subsp. lactis (LL), Lacticaseibacillus casei 01 (LC), and Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus (CONV). A total of 132 children (7-14 years old) participated in two study phases: development (n = 32) and validation (n = 100) of the list. Fifteen emoji were selected to be included in the product-specific list, which had a high frequency of citations in the first phase. The formulations with the highest overall liking (LL, BB, LC and CONV) were correlated with positive emoji, while the least-liked formulations (LA3 and LA5) were associated with negative emoji. Furthermore, the utilisation of emoji enabled the differentiation among formulations with similar overall liking. Therefore, this study developed and validated an emoji list to be used in the evaluation of fermented milks by children. The results suggest that the type of probiotic culture impacted the sensory characteristics of fermented milks, supporting the use of Bifidobacterium, L. lactis or L. casei in these products.

[PMID: 32947969 PMCID: PMC7555141 DOI: 10.3390/foods9091307] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 09/11/2020] [Accepted: 09/13/2020] [Indexed: 02/06/2023] Open
Abstract
Ongoing research has shown that emoji can be used by children to discriminate food products, but it is unclear if they express emotions and how they are linked to emotional words. Little is known about how children interpret emoji in terms of their emotional meaning in the context of food. This study aimed at investigating the emotional meaning of emoji used to describe food experiences in 9–13-year-old pre-adolescents and to measure related age and gender differences. The meaning of 46 emoji used to describe food experience was explored by: mapping emoji according to similarities and differences in their emotional meaning using the projective mapping technique, and linking emoji with emotion words using a check-all-that-apply (CATA) format. The two tasks gave consistent results and showed that emoji were discriminated along the valence (positive vs. negative) and power (dominant vs. submissive) dimension, and to a lower extent along the arousal dimension (high vs. low activation). In general, negative emoji had more distinct meanings than positive emoji in both studies, but differences in nuances of meaning were found also among positive emoji. Girls and older pre-adolescents (12–13 years old (y.o.)) discriminated positive emoji slightly better than boys and younger pre-adolescents (9–11 y.o.). This suggests that girls and older pre-adolescents may be higher in emotional granularity (the ability to experience and discriminate emotions), particularly of positive emotions. The results of the present work can be used for the development of an emoji-based tool to measure emotions elicited by foods in pre-adolescents.
