Quantitative Descriptive Analysis (QDA) services

Quantitative Descriptive Analysis (QDA) is a behavioral sensory evaluation approach where panel members use their senses of sight, sound, smell, taste and touch to measure a product's sensory characteristics. The methodology was developed by Dr. Herbert Stone, a food scientist and Dr. Joel Sidel, a trained psychologist in 1970s at Stanford Research Institute (SRI). To obtain sensory information for product development and marketing, descriptive analysis is widely regarded as the most useful approach because of the information it provides.
