Quantitative Descriptive Analysis

Quantitative Descriptive Analysis (QDA) is a scientific method used to evaluate and describe the sensory qualities of a product—such as taste, aroma, texture, and appearance—using trained panelists. Participants measure these attributes objectively on specific scales, providing detailed, numerical data. This approach helps businesses understand the detailed sensory profile of their products, compare different samples, and identify qualities that influence consumer preference. Essentially, QDA translates sensory perceptions into precise, quantifiable information, supporting product development, quality control, and marketing decisions with clarity and consistency.
