This study aimed to examine the perceptions and preferences of Brazilian adult consumers about four different front-of-pack (FOP) food labeling systems proposed by the Brazilian National Health Regulatory Agency.

This is a qualitative study conducted with 33 participants allocated in six focus groups. Four different types of FOP labels were displayed on processed and packaged bread: three interpretive warning labels (black triangle, black octagon and red ellipse) and a hybrid model (nutritional traffic light). Thematic analysis was used to identify the key topics addressed by participants.

Three topics were identified: label design, clarity and precision of information. The results demonstrated an influence of labels on product development and consumers' food choices. Most participants expressed a preference for black warning labels and reported the importance of statements endorsed by the Ministry of Health, which provide credibility and could influence food choices. Furthermore, participants agreed that the traffic light system provides more information but is difficult to interpret when comparing products. Warning labels were reported to have the greatest influence on purchase decisions. However, participants were concerned about how to understand the lack of warning labels on some products.

The results may help and support the Brazilian Health Regulatory Agency to identify and recommend the most effective FOP labeling system to be adopted in Brazil.

Few studies investigating adult consumers' perceptions of different FOP label formats have been conducted in the Brazilian context. Our study contributes to the small pool of evidence on the topic by demonstrating that FOP labels can be helpful for consumers when they are presented in an intuitive, interpretative and trustworthy format.

This paper aims to explore the intersection between service and social innovation, using a service-dominant logic (SDL) ecosystem approach to analyze how service innovations cocreate transformative value for individuals and communities.

A case study, with different data sources, is used to understand different innovations in a program that provides financial training to women in poverty in Colombia.

In the program’s service ecosystem, actors worked in tandem to develop dialogical service innovations. These service innovations transformed into social innovations, cocreating transformative value at different levels of the service ecosystem, including beneficiaries, families and communities.

First, this study illustrates how, during service value cocreation experiences, a dialogical innovation path occurs with the simultaneous participation of different service entities. Second, it uses transformative value cocreation to integrate service and social innovations conceptually. Third, it reveals how service innovation cocreates transformative value at different levels of the service ecosystem. Fourth, it shows how technology in its material and immaterial forms, working as an operand and operant role, respectively, facilitates service innovations.

This study illustrates how a wider service focus including all actors involved, in addition to a holistic view of beneficiaries, can prompt service and social innovations.

Service and social innovations have been seen as parallel fields. This study uses SDL to integrate these types of innovation processes and outcomes by applying the concept of transformative value.
