IntechOpen Sensory Analysis in Food Science - Integration of Emo-Sensory Studies, Sensory Tests, and Artificial Intelligence (Food Science and Nutrition)

Sensory analysis is a fundamental discipline in food science, essential for product development, quality control, and consumer research. It provides a structured scientific framework for translating subjective sensory perceptions, such as taste, aroma, and texture, into objective, measurable data. Traditionally, sensory evaluation has relied on descriptive analysis, discrimination tests, and affective tests to assess product attributes and consumer preferences. Descriptive analysis, conducted by trained panels, quantifies sensory characteristics, while affective tests evaluate consumer liking and acceptance. Recent advances have expanded sensory analysis to include emotional and psychological dimensions of food perception. Through physiological and biometric measures such as facial expression recognition, heart rate monitoring, and eye tracking, researchers can capture implicit emotional responses during food consumption. This emerging field, known as emo-sensory research, bridges sensory science and affective psychology, emphasizing the role of emotions in shaping consumer choice, satisfaction, and loyalty. Tools like FaceReader® and EEG-based analyses allow for the objective mapping of emotional reactions to food experiences. Artificial intelligence (AI) has further transformed sensory science by introducing powerful tools for data modeling and prediction. Machine learning algorithms analyze complex sensory and consumer datasets to detect patterns, forecast preferences, and optimize formulations. The integration of sensory science, emo-sensory approaches, and AI opens new possibilities for understanding human–food interactions. Future developments will likely emphasize hybrid human–AI sensory systems, ethical data handling, and standardized methodologies, leading to more personalized, emotionally engaging, and sustainable food innovations.
