• Purchase preferences (PP) based on taste alone were in favor of the meat product. • Packaging induced a significant increase in the PP for the plant-based product. • Health information increased in the PP and the WTP for the plant-based product. • Environmental information increased in the WTP for the plant-based product. • Our results militate in favor of the dissemination of additional information. Scientific literature has shown that a partial replacement of meat-based foods with plant-based foods would be beneficial for public health and the environment. However, both lack of sensory attractiveness and lack of consumer awareness regarding benefits of rebalancing diets in favor of plant protein partially explain the low market shares for meat alternatives. In the context of a possible substitution of a meat product (pork-based sausage) by a visually very close counterpart based on vegetable proteins, the objective of this work was to study the possibility of changing consumer preferences towards the plant-based product by gradually providing information concerning the health or environmental consequences of producing and consuming both types of products. We studied consumers' preferences after a blind tasting, after a tasting in the presence of the packaging, and after the dissemination of two stages of information. The assessment of consumer preferences was carried out using purchase preferences (PP) and willingness to pay (WTP). After the blind tasting, PP were clearly oriented towards the meat product. After the tasting with packaging information, the gap between the two products narrowed, but PP were still turned towards the meat product. The dissemination of a first informative message about either health or the environment was not enough to modify consumers' WTP. Adding a second message concerning health led to an equivalence of the two products studied in terms of WTP and PP. The combination of the two environmentally informative messages also made it possible to obtain an equivalence of the WTP for both products, but the PP were still turned towards the pork product. This suggests that the impact of additional information depends on the information disseminated. Overall, these results militate in favor of the dissemination of information presenting the consequences of the consumption of meat-based or vegetable protein-based products. [ABSTRACT FROM AUTHOR]

• Liking and WTP for three cheeses, including two innovative ones, were measured. • Information was given: nature of the process, health and environment benefits. • Information about the new process did not change WTPs for the new cheeses. • Increase in WTPs for the new cheese following health and environment information. • Health and environment information compensated for a liking difference. The objective of this work was to study the reaction of consumers to a technological innovation (a radically new manufacturing process) applied to a traditional product (cheese). A traditional cheese and two cheeses resulting from a new sustainable process were evaluated by 142 consumers. These cheeses were first evaluated blind, giving rise to liking score and willingness to pay (WTP). Following a message concerning the nature of the processes used for the three cheeses, the consumers gave their WTP once again. The last two stages of the protocol consisted of successively revealing two pieces of information concerning the benefits of the new process for health and the environment and in measuring, at each of these two stages, the WTP of the consumers. Blind tasting showed that the two new cheeses were less appreciated than the traditional cheese. The information concerning the nature of the processes used did not significantly influence the WTP of the new cheeses but caused a revaluation of the traditional cheese. Information on the benefits of the new process has reduced the gap between the WTP of the three cheeses by decreasing the WTP for the traditional cheese and increasing the WTP for the new cheeses. This information made it possible to compensate for differences in liking of 1 to 2 points on a scale of 10. However, there is heterogeneity in consumer reactions. Indeed, some consumers (23%) did not appreciate the sensory properties of the new cheeses, and despite the assimilation of the information concerning the benefits of the new process, their WTP remained lower than those of traditional cheese. These results show that there is no major opposition to the application of technological innovations to traditional products such as cheese and that information concerning health and environmental benefits is positively accepted.

• We combined hedonic and willingness to pay (WTP) approaches to study consumer behavior. • Information about nutritional and environmental impacts may promote dietary transitions. • Participant preference increased as the product's pea percentage decreased. • WTP increased with hedonic preferences but was differentially affected by nutritional and environmental information. • Developing fermented products that mix animal and plant protein sources is a major challenge. • Partially replacing animal ingredients with plant ingredients could enhance dietary sustainability. Consumers are being encouraged to increase the proportion of plant protein in their diets to enhance the sustainability of food systems. One approach is to develop plant-protein-rich foods that are acceptable to consumers. This study examined French people's reactions to cheese alternatives—new fermented products that mixed animal and plant protein sources. We conducted experimental sessions with 240 French participants to assess their responses to three fermented products containing different percentages of yellow pea and cow's milk. First, we asked the participants to blind-taste the three products and solicited hedonic scores of products. We then provided the participants with simple information about the products' composition and asked them to taste and score the liking of the products a second time. We also asked consumers to estimate their willingness to pay (WTP) for each product before and after revealing additional information about the nutritional or environmental benefits of consuming pea-based foods. The product with the lowest percentage of pea and the highest percentage of milk received the highest hedonic scores, and WTP was correlated with the hedonic scores. The additional information about the nutritional and environmental benefits of pea-based foods led to significant increases in WTP for two of the fermented products, but not for the least preferred product, namely the one with the highest percentage of pea. This finding suggests that participant reactions to information depended on hedonic preferences. [ABSTRACT FROM AUTHOR]

• A pleasure-centred intervention was developed to improve the pleasure to consume healthy foods. • The relationship between liking and perceived healthiness increased after the intervention. • Liking for two unhealthy foods decreased for children in the intervention group. • A highly attractive unhealthy food is chosen anyway. • Some efforts should be made to regulate advertising of unhealthy foods for children. The aims of the present study are to assess the impact of a pleasure-oriented intervention on the nutritional quality of midafternoon snacks chosen by mother-child dyads and to evaluate the evolution of the relationship between the liking and perceived healthiness of the food items offered for the snack choices. Data were collected at two laboratory sessions (T1 and T2), during which children and mothers were separately asked to choose two food items (among 10) for a midafternoon snack, first for themselves and then for the other dyad member. Participants also rated their liking and perceived healthiness of the 10 food items. After T1, dyads were randomly assigned to an experimental group (N = 94) with an in-home pleasure-oriented intervention to stimulate the pleasure of consuming healthy foods or to a control group (N = 93). Our study shows the lack of a significant effect of the intervention on the nutritional quality of snacks chosen at T2. However, for the children in the experimental group, the relationship between liking and perceived healthiness which was not significant at T1 (τ median = −0.05, P = 0.56) became significant and positive at T2 (τ median = 0.13, P = 0.002). Moreover, this increase of the relationship in T2 was significantly higher for the experimental group compared to the control group (P = 0.05). For mothers, the existing relationship between liking and perceived healthiness at T1 (τ median = 0.27, P < 0.001) increased significantly between T1 and T2 (P = 0.006) only in the experimental group, even if this increase was not significantly higher compared to the control group (P = 0.21). Since the relationship between food liking and perceived healthiness in mother-child dyads increased after the intervention, one could argue that this higher positive attitude towards healthy foods could constitute the first step in a behavioural change in favour of healthier choices.

The aim of this study was to assess the impact of a nutritional traffic-light label, the Nutri-Score, on snack choices in mother-child dyads and to assess a potential hedonic cost associated with a change in favour of healthier choices. French mothers and children (n = 95; children's age: 7-11 years) who participated were asked to choose, for themselves and for the other dyad member, a snack composed of one beverage and two food items selected among several products with different nutritional quality. In the first step, the products were presented without any information. In the second step, the products were labelled with the Nutri-Score. Mothers and children were asked to rate their liking for all proposed products before being informed of their nutritional quality. The nutritional quality, the hedonic score, and the estimated budget of the selected snacks were compared before and after labelling. As hypothesized, the Nutri-Score label led to a significant increase in the nutritional quality of the chosen snacks. The budget for the chosen snacks was unchanged or decreased after the nutritional labelling was applied. Children and mothers had significantly lower liking for the snacks after nutritional labelling than before nutritional labelling, suggesting a hedonic cost associated with a change in favour of healthier snack choices. This raises the question of the sustainability of the behavioural change induced by the Nutri-Score label. [ABSTRACT FROM AUTHOR]

We compare consumers' attitude towards and willingness to pay (WTP) for gene-edited (GE) apples in Europe and the US. Using hypothetical choices in a lab and different technology messages, we estimate WTP of 162 French and 166 US consumers for new apples, which do not brown upon being sliced or cut. Messages center on (i) the social and private benefits of having the new apples, and (ii) possible technologies leading to this new benefit (conventional hybrids, GE, and genetically modified (GMO)). French consumers do not value the innovation and actually discount it when it is generated via biotechnology. US consumers do value the innovation as long as it is not generated by biotechnology. In both countries, the steepest discount is for GMO apples, followed by GE apples. Furthermore, the discounting occurs through "boycott" consumers who dislike biotechnology. However, the discounting is weaker for US consumers compared to French consumers. Favorable attitudes towards sciences and new technology totally offset the discounting of GE apples., (Copyright © 2020 Elsevier Ltd. All rights reserved.)
