Neuroorganoleptics: Organoleptic Testing Based on Psychophysiological Sensing

Area of Science:

• Consumer Behaviour
• Neuroscience
• Sensory Science

Background:

• Traditional food and beverage research relies on self-report and organoleptic assessments.
• Advancements in psychophysiological data acquisition enable deeper insights into affective states.
• Integrating psychophysiological data offers a natural evolution for organoleptic testing.

Purpose of the Study:

• To propose and validate a protocol for neuro-organoleptic analysis.
• To combine traditional sensory evaluation with psychophysiological data acquisition.
• To identify best practices for laboratory settings and data collection in sensory testing.

Main Methods:

• Developed a neuro-organoleptic analysis protocol.
• Applied the protocol in the MobFood case study with 83 participants.
• Collected psychophysiological data alongside preference and acceptance tasks across three sessions.

Main Results:

• Identified specific Heart Rate Variability (HRV) features.
• Demonstrated a strong correlation between HRV features and self-reported participant preferences.
• Derived practical lessons for conducting psychophysiological data acquisition in sensory studies.

Conclusions:

• Neuro-organoleptic analysis is a viable method for enhancing sensory evaluation.
• Psychophysiological data, particularly HRV, offers objective measures of consumer response.
• The proposed protocol provides a framework for future research in neuro-organoleptics.
