Implementing Sensory Analysis Principles in the Quality Control of PDO Products: A Critical Evaluation of a Real‐World Case Study

摘要: This study describes and analyses a practical implementation of basic sensory analysis principles in productive context related to typical products. As case study, we investigated the quality control (QC) system Trentingrana cheese, variety protected designation origin Grana Padano. The production cheese factories is supervised by their consortium through assessment attributes an expert panel; and, depending on evaluation, associated dairies receive price premiums or penalties. procedures applied data collected over 8 years were evaluated, critical points identified. Ameliorations suggested accordance with good practice verified additional 3-year period. QC has been improved increasing number evaluated samples proportionally amount each dairy, introducing balanced experimental design, monitoring experts' performance controlling sample presentation avoid systematic effects psychological errors. Practical Applications With this work, demonstrate viability applying approach within food industry proposed here compromise between constraints implementing testing industrial requirements for collecting reliable data. Nevertheless, implemented represents example efficient strategy product valorization, fundamental preserving both market position consumer confidence loyalty toward product.
