An electrochemical sensor for detection of beef taste was designed in this study. This sensor was based on the structure of polyvinyl chloride/polypyrrole (PVC/PPy), which was polymerized onto the surface of a platinum (Pt) electrode to form a Pt-PPy-PVC film. Detecting by electrochemical methods, the sensor was well characterized by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The sensor was applied to detect 10 rib-eye beef samples and the accuracy of the new sensor was validated by sensory evaluation and ion sensor detection. Several cluster analysis methods were used in the study to distinguish the beef samples. According to the obtained results, the designed sensor showed a high degree of association of electrochemical detection and sensory evaluation, which proved a fast and precise sensor for beef taste detection.

在这项研究中设计了一种用于检测牛肉口味的电化学传感器。该传感器基于聚氯乙烯/聚吡咯（PVC / PPy）的结构，该结构聚合到铂（Pt）电极的表面上以形成Pt-PPy-PVC膜。通过电化学方法进行检测，通过电化学阻抗谱（EIS）和循环伏安法（CV）对传感器进行了很好的表征。该传感器用于检测10个肋眼牛肉样品，并通过感官评估和离子传感器检测验证了新传感器的准确性。研究中使用了几种聚类分析方法来区分牛肉样品。根据获得的结果，设计的传感器显示出较高的电化学检测与感官评估的关联性，
