Abbreviation for "Quantitative Descriptive Analysis", a basic methodology for analytical food sensory testing. A descriptive sensory analysis aims to identify and quantify sensory product characteristics by means of objective description of human perception and to reveal relationships between the chemical-physical components of a product and the sensory characteristics of this product by trained persons. The intensity of certain properties or characteristics is measured using an intensity scale. Such a quantitative descriptive analysis, which is also called profile analysis or profile testing, also makes it possible to graphically display the differences between several products for defined properties.
