Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so. Various metal oxide (MO) powders have been explored for electrochemical sensor as liquid or gas phase sensor. These materials can show ideal or near-ideal Nernstian responses due to their high conductivity, good chemical stability, and most importantly their superior biocompatibility. In this work, various MOs were used as non-specific sensor array for electronic tongue system. To fabricate the sensor, carbon nanotube (CNT) was mixed with several MO powders consisting of zinc oxide, cobalt oxide, copper oxide, iron oxide and copper iron oxide powders with the ratio of 1:1 by weight. These sensor arrays were used as array of working electrode for cyclic voltammetry (CV) measurement in electronic tongue system. To investigate the classification ability, the five different species of orange juice including Shogun, Tangerine, Valencia, Sainumpeung and Mandarin were used to perform the measurement. The 0.1M of NaOH, as electrolyzed solution, was added to enhance electrical conductivity with the ratio of 1:1 by volume. The CV signals were performed the preprocessing and extracted main feature by using wavelet analysis. In order to distinguish different types of orange juice, the extracted signals were classified by using principal component analysis. The result showed that these CNT electrodes modifying with MOs can be utilized to the electronic tongue application for orange juice classification with high stability. 2020-10-08T08:36:16Z 2020-10-08T08:36:16Z 2020 Chiang Mai Journal of Science 47,4 (Special Issue II : July 2020), p.776-785 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=11105 http://cmuir.cmu.ac.th/jspui/handle/6653943832/69887 Eng Faculty of Science, Chiang Mai University
