o:8839 Examination of the Content of Ionic Species in Peach in Pectin Fruit Products Using the Ion Chromatography Method en 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.
