Abstract: In this work, the content of ionic species in commercial pectin products from fruit: jams, marmalades and dietary jam sweetened with fructose from the market of the Republic of Serbia was examined, using the method of ion chromatography. The pH value of these products and total acidity were also tested. Fruit, which is the main ingredient of these products, contains the necessary macro and micro elements, vitamins and other biologically valuable substances, which are very important for the proper functioning of the human body. The elements such as Na, Mg, P, S, Cl, K and Ca are considered essential nutrients and are necessary in amounts in mg/kg per day. 2025 Keywords: onic species, ion chromatography, jams and marmalades, PCA http://creativecommons.org/licenses/by/4.0/legalcode https://unilib.phaidrabg.rs/o:8839 ISBN: 978-86-7132-089-4 Book of Abstracts - ISSS 2025 - 29th International Symposium on Separation Sciences startpage: 97 endpage: 97 info:eu-repo/semantics/conferenceProceedings Examination of the Content of Ionic Species in Peach in Pectin Fruit Products Using the Ion Chromatography Method application/pdf 2173500 bytes eng Faculty of Technology and Metallurgy, Research and Development Centre of Printing Technology Trajković, Dušan Božović, Jelena Živojinović, Dragan
