The provision of food information to consumers is well recognized to be problematic and complex, since it includes health, social, legal, as well economic aspects. Information provision through mass media and labelling is usually product/producer centred and it could not meet specific consumers’ needs. Novel approaches tend to adopt mobile app-based services as a way for consumers to get better food information. Potentially, these services could provide relevant information to consumers as they could address particular needs or expectations by leveraging on context-awareness, ubiquity, pervasiveness, and mobility features. Do current app-based services actualize these potentialities? This paper has a twofold to answer question delimiting the research scope to olive oil information domain and to propose a methodological approach that can be easily adapted to conduct reviews of app-based services providing consumers with information related to other food domains. The review methodological approach we propose consists in a sequence of steps (sample selection, data coding and extraction, and data analysis) aimed to investigate dimensional aspects (and their inter-relationships) of food information flow that occur in the interaction between a consumer/user and a food app-based service. In particular, we have applied it to discover possible relations between information categorization, provider type, social network capability, and information search capability in app-based olive oil information services. Although there are countless mobile apps aimed to assist consumers with their everyday food practices, little research has been devoted to investigate services providing consumers with food information delivered through a mobile app. The available research lacks in defining a methodological framework to be employed in analyzing the relevance of food information provided to targeted audiences by app-based services. Our research gives a contribution to fill this knowledge gap by presenting some methods that can be employed to conduct reviews of app-based food information services. Applicability of these methods has been shown for the olive oil information domain. Results from our review of mobile olive oil apps suggest some direction to conceive and develop innovative mobile olive oil apps that better exploit mobile/ubiquitous technology features. Moreover, methods we presented could be used to conduct other reviews in order to obtain fruitful insights for the design of a new generation of food-apps or to identify potential service delivery improvements within the so-called “internet of food” domain.
