Exploring the application of digital technologies in food information to consumer: a systematic literature review

Purpose The application of digital technologies in food information is profoundly transforming how consumers access, interpret and use nutritional information. This paper systematically reviews digital technologies integrated into food labelling systems and evaluates their impact on consumer behaviour, transparency and informed decision-making. Design/methodology/approach A systematic literature review (SLR) was conducted following the PRISMA protocol, covering peer-reviewed studies published between 2013 and 2025. The search, performed in Scopus and Web of Science, focused on the role of digital technologies in delivering nutritional information to consumers. Findings Based on the systematic analysis of 32 peer-reviewed studies, the findings show that digital technologies have a multifaceted role in food information, shaping consumer behaviour, strengthening trust and traceability, supporting research and enabling personalised information platforms. Their effectiveness, however, depends on governance, design and user engagement. The study highlights the growing need for standardised global regulations to ensure data accuracy, accessibility and consumer protection across digital labelling ecosystems. Originality/value This review bridges the gap between digital technologies and consumer food information policy, offering an interdisciplinary perspective on the digital transformation of food information. It contributes to food systems scholarship by framing digital technologies as dynamic tools that mediate knowledge, trust and nutritional behaviour in increasingly data-rich food environments.
