In the pursuit of more sustainable diets, researchers have been studying ways to promote a transition from animal- to plant-based meals in foodservice contexts by influencing participants' conscious choices through names, labels, claims, and information. This critical review found that these interventions usually mobilize only those already engaged in reducing the consumption of animal products and often only during the intervention period, failing to influence those who eat most meat or to create long-lasting effects. Analyzing the choice for vegetarian meals against meals with meat in recently published studies conducted in foodservice contexts, we argue that the transition to more sustainable diets should rely less on consumers' willpower and more on public policies and institutional measures that change the availability, price, and visibility of plant-based meals. Inspired by behavioral sciences, this paper discusses interventions that challenge meals with meat as the default option and suggests hybrids as a path to increase the availability, convenience, and sensory familiarity of vegetarian meals. The paper ends with proposals for questions, interventions, metrics, and issues to be researched by consumer science, including questions on the degree of freedom of consumers' choice and what would be the ethical limits to telling half the truth about hybrids.

For the sake of both the environment and human health, it is necessary to reduce meat consumption. However, increased consumer adoption of plant-based meat alternatives (PBMAs) will only occur when such products are attractive. PBMAs with meat-like sensory attributes and those that can be cooked similarly to meat are known to be preferred, but the preference for meat-likeness varies depending on the consumer's attitude towards meat. This study determined the relationship between consumers' level of meat attachment (MA) on their sensory perceptions of and preference for commercial PBMAs, and their drivers of liking. MA was measured by the Meat Attachment Questionnaire (MAQ); consumers with either low or high MA (LMA and HMA, respectively) were invited to participate in the study (n = 99). The sensory characteristics of seven PBMAs were evaluated using a rate-all-that-apply (RATA) questionnaire, along with an ideal profile and product hedonics. Consumers with LMA had significantly higher overall, aroma, and taste liking, compared with consumers with HMA. Both LMA and HMA consumers similarly discriminated among the sensory properties of PBMAs and the ideal profile. Nevertheless, a further adapted penalty analysis showed subtle differences in consumers' penalisation of sensory attributes depending on MA level. These findings could be used for future research and the development of PBMAs based on consumers' MA; they could also be extended for application in a meal context where the PBMAs are consumed.

In this chapter, the author summarises arguments in favour of including sensory and consumer science in the curriculum for the training of culinary expertise. As part of teaching sensory methods, an understanding of physiology and perceptions of the senses are crucial. Through lectures and laboratory work, students are trained to be aware of their own sensory ability and to be able to understand and to use one-self as a tool in their practical work as a chef or sommelier. Different sensory methods are presented in the chapter along with along with discussion of what consumers consider to represent quality when choosing products. Finally, the author argues for the importance of sensory training in promoting the active participation of culinary experts in the green transition towards food consumption that is beneficial to environmental and public health as well as animal welfare.

The transition to more diversified protein sources presents legumes, such as peas, as excellent alternatives to animal protein. In light of this shift, understanding the sensory variation of pea genetic resources becomes crucial in broadening their appeal and promoting greater consumption. This study aimed to identify key factors influencing the sensory attributes of landrace peas, including variety (accession), location (geographical area of cultivation), and harvest year. Through a quantitative descriptive sensory analysis of six Swedish landrace pea accessions, cultivated over 1–2 years in three different Nordic countries, we analyzed the sensory attributes in detail and evaluated potential interactions between the pea accessions, their respective growing locations, and the varying harvest years. The results show that the sensory variation in the studied landrace pea accessions is primarily attributed to the chosen accession, despite the differences in location and harvest year. Notably, the results also reveal the potential impact of the location on the perceived sourness and umami taste of peas. These findings underscore the critical role of careful variety selection and breeding to enhance the sensory experience of peas, enabling the development of diverse pea-based products that cater to consumer preferences.

From a sustainability and food-supply perspective, it is crucial to contribute to a reduction of food waste, such as meat raw materials, and to develop knowledge on how to make underexploited foods acceptable for inclusion on restaurant menus. This study applies a gastronomy perspective that integrates culinary arts with sensory science to support knowledge development and creativity in the restaurant industry. The aim was to explore locally produced mutton in collaboration with culinary craft practitioners and food producers, in a Swedish context. An additional aim was to design an applied model for creative and innovative meal solutions that are both sensory approved and sustainable. This was done through a combination of sensory evaluations and culinary workshops. This mixed-methods approach was used to merge qualitative and quantitative data to gain complementary views on the research problem. Identifying the knowledge and experience of lamb producers and culinary staff, was done by using sensory methods in connection with a qualitative approach that focused on observing cooking activities, conversations and group talks among participants. The sensory results indicated that mutton is a fully edible food material and can thus be defined as an unutilized gastronomic resource. Among the workshop participations, overall liking was high and evenly distributed between the mutton dishes. The main outcome of this study was the provision of a model for sustainable resource management of locally produced food. This model can be used for understanding the importance of the locality, sustainability and cultural acceptance of products, in addition to the value chains and network practices embedded in direct supply-chain relationships. From a long-term perspective, this understanding may lead to increased awareness, knowledge and skills among producers and restaurants regarding the benefits and opportunities of locally produced food.

A plant-rich meal pattern is widely considered to be one possible solution for a shift towards a more sustainable food culture that considerably decreases food-related greenhouse gas emissions globally. The public meal, in particular school meals, can ideally become a platform for developing multisectoral cooperation through culinary action, transforming food from being a commodity to part of a strategic solution with societal outcomes. The aim of our study is to support a shift toward more sustainable meal solutions within the public meal sector. The objective is to introduce the check-all-that-apply (CATA) method in a large real-life consumer study, using only one food product, during a lunch break, and still account for the variation in perception between consumers. The objective is also to explore strategic multi-sectoral insights for introducing new foods to a larger population for a shift toward a plant-rich meal pattern. In this study, we established a cooperation between a small-sized food company, four schools and a university in Sweden. A plant-based sausage roll based on minced grey peas was developed. The likes and dislikes of 800 t(w)eens being served the grey pea roll were checked using hedonic values and CATA questions and compared with an ideal. To understand which CATA terms were persistent (meaning relevant, liked and just-about-right across consumer clusters), results including frequency scores, consistency, mean impact on liking, just-about-right scores and agglomerative hierarchical clustering were combined in an extended statistical processing. Our results show that unique/novel and natural were the only persistent CATA terms; these terms should therefore be interesting candidates for further improvement regarding classification and conceptualization of plant-based products in public meals. The CATA term vegetarian, on the other hand, can both increase and decrease liking scores.
