,Introduction to the Notes
Overview of the Content Covered
These notes on Sensory Evaluation provide a comprehensive understanding of the scientific principles
and practical applications of sensory analysis in food science and product development.
The following topics are covered in detail:
Concept and Definition of Sensory Evaluation
• Meaning and importance
• Role of human senses in food evaluation
