Abstract

Abstract The principles of the electronic tongue sensor include potentiometry using a type of electrode with a liquid junction design. Mint leaves are widely used in the industrial sector in food, beverage, and medicinal products. In the industrial sector there are obstacles in the quality control process when analyzing the content in beverage products, in which the tools are unable to accurately classify the ingredients in the product. The content of a mixture of mint and tea was tested using seven working electrodes coated with different lipid membranes and classified using principal component analysis (PCA) and linear discriminant analysis (LDA). The electronic tongue was tested on a solution representing the five basic tastes. The accuracy of the readings of each sensor was obtained using a support vector regression (SVR) linear model with the mean absolute error (MAE) equal to 0.43 and a correlation coefficient ( ) of 0.93.

基于电位法脂膜的电子舌主成分分析和线性判别分析对茶叶中薄荷的分类

电子舌头传感器的原理包括使用一种具有液体结设计的电极的电位测定法。薄荷叶广泛应用于食品、饮料、医药等工业领域。在工业领域，饮料产品的含量分析在质量控制过程中存在障碍，工具无法准确地对产品中的成分进行分类。采用涂有不同脂质膜的7个工作电极对薄荷茶混合物进行了含量测定，并用主成分分析(PCA)和线性判别分析(LDA)对其进行了分类。电子舌头在代表五种基本味道的溶液上进行了测试。各传感器读数精度采用支持向量回归(SVR)线性模型，平均绝对误差(MAE)为0.43，相关系数()为0.93。

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
