This systematic review examines the impact of neuromarketing strategies used by sustainable food and beverage brands on consumer emotions and cognitive responses. Neuromarketing provides insights into consumer behavior, making it relevant for the food sector, but applying its techniques requires understanding factors that influence consumer choices. The study synthesizes empirical evidence on how neuromarketing affects emotions and cognition in sustainable brands, identifying knowledge gaps for future research. Analyzing 22 studies, the results show that neuromarketing can enhance emotional connections, build trust, and promote loyalty using techniques like EEG, fMRI, eye tracking, and galvanic skin response. These strategies shape emotions through sensory stimuli and affect cognition by targeting specific brain regions, influencing purchasing decisions. Future research should address current limitations and further explore neuromarketing's applications in this sector.
