Sensory Evaluation of Food

Sensory Evaluation of Food is a scientific discipline that applies principles of experimental design and statistical analysis to use the human senses—sight, smell, taste, touch, and hearing—as instruments for measuring, analyzing, and interpreting the characteristics of food and materials. This field is critical in food science for a variety of purposes, including new product development, quality control, shelf-life studies, and understanding consumer preferences and acceptance. By using trained panelists or large consumer groups under controlled conditions, sensory evaluation provides objective data on attributes like flavor, texture, and appearance, bridging the gap between chemical/physical properties and the human perception of a product.
