2D Pattern Recognition of White Spirit Based on the Electrochemical Profile Recorded by Screen-Printed Electrode

Abstract

The rapid identification of liquor is valuable for both research and food safety purposes. However, rapid and accurate identification has been difficult because most of the current analysis methods are lab-based. In this work, we established an electroanalytical technique to detect the distribution of electrochemically active compounds in liquor. Because the chemical composition of different varieties is largely controlled by the fermentation process, this method has considerable potential for liquor identification. Six brands of nongxiang-flavor liquors were collected to confirm the feasibility of the proposed methodology. PCA and 2D pattern recognition were used for identification. The results indicate that the electrochemical profiles of the six brands can be distinguished using their voltammetric data.

Electrochemical Voltammogram Recording for Identifying Varieties of Ornamental Plants

“…The recorded voltammograms of Clematis were then submitted for pattern generation. Scatter plots and 2D density patterns have previously been used for plant identification [38][39][40][41][42][43][44][45]. In this work, we further proposed a hot map pattern for variety identification.…”

Preparation of Electrochemical Sensor Based on Zinc Oxide Nanoparticles for Simultaneous Determination of AA, DA, and UA

“…In view of the important medical research value of detecting the contents of these three substances, rapid and accurate detection methods are essential for the diagnosis (Abellán-Llobregat et al, 2018 ). In recent years, the detection of AA, DA, and UA has attracted considerable attention (Fu et al, 2019 , 2020 ; Shamsadin-Azad et al, 2019 ; Karimi-Maleh et al, 2020c ; Zhou et al, 2020 ).…”
