Fruit juice is the product obtained by mechanical processing of one or more types of technologically ripe, fresh, chilled or frozen fruit, which is not but can be fermented, the taste, color and aroma of which must be specific to the type of fruit from which the fruit juice is produced. Fruit juices are important in the human diet since they contain different nutrients, especially vitamins, minerals and carbohydrates. In this paper the content of Ag, Al, B, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Sr, Zn, Si, As, P, Mo and Sb in clear orange juices found the local market on the territory of Leskovac was investigated. The preparation of the samples was done by wet digestion. The concentrations of elements after digestion were determined by Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES). Based on the obtained results it can be concluded that all investigated samples of clear orange juices do not have the required level of potassium and phosphorus. On the other side, due to high levels of molybdenum and arsenic, the consumption of clear orange juices in higher amounts could lead to a greater intake of these elements and potentially unwanted adverse effects.
