This paper aims to examine the image realism effect, studying how changing the front-of-package visual affects the acceptance of an insect-based food by consumers. By comparing reactions to realistic and less realistic images of an insect as an ingredient, this research investigated how visual imagery can affect consumers’ responses, reducing perceived disgust or increasing expected taste.

Three experiments studied the impact of realistic (photo) versus less realistic (drawing) images for two types of insects (mealworm, cricket) on consumers’ psychological distance from the image, perceived disgust, expected taste, willingness to eat, purchase intention and food choice.

Study 1 demonstrates that using a less realistic insect image reduces perceived disgust, with psychological distance from this image and perceived disgust mediating realism effect on willingness to eat. Study 2 shows that a less realistic insect image, perceived as more remote, improves expected taste and willingness to eat. Study 3 confirms the results by measuring behavior: consumers were more likely to choose the product with the less realistic image.

The research focused on one kind of product and two ways of depicting this product, limiting the generalizability of the findings for other visual representations and product categories.

The findings suggest how brand managers can use the image realism effect on the packaging of novel, sustainable products to influence consumers, reducing their disgust and increasing their expected taste.

This research breaks new ground by explaining how visual cues on packaging affect the acceptance of insect-eating, drawing on construal level theory.

Aversion linked to disgust and neophobia is the primary reason for human reluctance towards edible insects as a sustainable food source. Stimulating positive emotions may overcome these mental barriers. Cute visuals and claims on product packaging can trigger positive affective responses in consumers whilst modulating taste expectations. This study investigated how these elements influence emotions, perceptions and attitudes towards insect-based foods.

An online cross-cultural study involving French (n = 747) and Colombian (n = 695) consumers was conducted using two insect-based products: chips (hedonic) and bread (functional). Ten visual packaging variations were created per product, emphasising palatability, sustainability, nutrition and popularity (plus a control: no claim) affixed to the image of a cute anthropomorphic cricket or its silhouette. Visual appreciation and associations were assessed along with the participants' degree of food variety seeking, familiarity with entomophagy and openness to consuming edible insects.

Differences were reported in emotions, perceptions and attitudes based on the combination of packaging elements, product type and consumer segments. The findings suggest that food marketers should use cute insect depictions linked to palatability-focussed claims to alleviate young French adults' reluctance towards insect-based foods (IFs). Colombians responded better to pro-social claims and neutrally to cuteness.

The results should be valuable to stakeholders seeking to enhance food marketing strategies related to IFs amongst target consumer segments.

This study is the first to assess how baby schema cuteness induces emotional changes towards IFs and how it affects perceptions and attitudes amongst distinct populations and age segments.

A product colour plays an important role in consumers’ preferences. The purpose of this paper is to highlight the impact of the three-dimensional character of colour (brightness, saturation and vividness) on children’s behaviour towards a food product and as a source of well-being.

Two experiments were conducted. Study 1 was conducted with 62 children and used four visuals of syrup presenting two colours (red/green) and two variations of vividness (vivid/dim). Study 2 was conducted with 70 children and used four pictures of stewed apples and four pictures of pouches to test the influence of each dimension of colour on children’s preferences for the product and the product packaging.

Results show that the three-dimensional character of colour plays an important role in children’s gustatory inferences and well-being.

The study is restricted to one food product (in each study) habitually consumed by children. Other products could be investigated to show how colour can contribute to children’s well-being.

The paper addresses the issue of well-being as a potential brand-positioning element.

The paper suggests new avenues to use the brightness/saturation or vividness of a product or packaging colour as a potential element to arouse positive sensations that generate children’s well-being even when the product is not a preferred one.

This works initiates creative thinking concerning the impact of a product colour on children consumers.

While recent academic research on entomophagy has predominantly focused on adults, the purpose of this child-centred research is to obtain a better understanding of young consumer acceptance of insect-based foods.

Two qualitative studies were conducted with a total of 43 French children aged 8–13 years. Study 1 (n = 22), based on semi-directive interviews, and Study 2 (n = 21), based on focus groups, included projective techniques and exposure to different types of insect-based products to help children express their feelings and thoughts.

The evidence shows that in Western children’s minds, insects are considered as culturally non-edible. Children predominantly reject insects as food because of their sensory properties and the disgust they arouse. However, their interest in eating insect-based food is embedded within experiential contexts specific to childhood, in particular the peer group, which makes insect-eating fun and challenging, and the family, which offers a protective and reassuring setting.

The authors advocate changing children’s sensory perception of insect-eating food through sensory and participatory activities. Manufacturers and policymakers should also draw on children’s peer culture to associate insect-eating with positive social experiences and foster peer influence.

Drawing on cognitive psychology theories and the literature in food science on food rejection, the authors contribute to emerging consumer research on alternative food consumption (AFC) focusing on cognitive, emotional and social factors of acceptance or rejection of insect-based foods by children.

The purpose of this paper is to propose an agile methodology for the development of food products that has two key characteristics: (1) consumers are included as co-creators and (2) the assessment of environmental impacts plays a central role.

In collaboration with a French small-to-mid-size enterprise, a research-intervention approach was used to test the agile methodology designed, which features three iterative runs of food product development. In each run, prototypes were presented and modified with consumers during focus groups. Life cycle analysis assessed the relative environmental impacts of the prototypes. The research data from consumers were mainly qualitative.

The main result of this work is the implementation of a methodology to develop new food products in an efficient way by integrating consumers' insights and environmental concerns simultaneously. The method was successful in integrating consumers as co-creators and in drawing attention to the potential environmental effects of different prototypes for the decision-making process.

The research is based on a single case study. Thus, generalisation to other companies is limited. The authors invite further research focussed on different types of companies. The methodology and the tools could be modified to suit a variety of contexts.

This work addresses the need for guidelines to integrate consumers and environmental considerations into the food development process by testing an agile methodology with a company. It contributes to the scope of sustainable and consumer-oriented food innovation management.
