Commercially available fruit jams, juices and concentrates contain different physiologically and nutritionally important compounds, e.g. bioactive phytochemicals (phenolic, flavonoids, carotenoids etc.) and vital nutrients (proteins, carbohydrates and vitamins). An increased popularity and demand for these food items is due to increased awareness about healthcare and average life expectancy in society. All these reasons make fruit products very widely consumed in both developed and developing countries by different age groups. Apart from nutritional and functional compounds, fruit juices contain many major (macro elements like Ca, K, Mg etc.), minor (micro elements like Cu, Fe, Mn, Zn etc.) and trace elements (As, Cd, Cr, Pb, Hg, Se etc.).
