Comparative evaluation of some macro- and micro-element and heavy metal contents in commercial fruit juices

摘要

Micro- and macro-element contents of several commercial fruit juices purchased from marked were determined by inductively coupled plasma atomic emission spectroscopy. Among the minor elements determined, Zn, Cu, Mn, Mo, Co, Cd and Ni were found to be lover. Major mineral contents of fruit juices were established as Ca, K, Mg and P. The potassium contents of fruit juices were determined at the higher levels. K contents of fruit juices ranged between 475 mg/kg (B apricot) and 1478 mg/ kg (B peach). In addition while Ca contents of fruit juices change between 19.3 mg/kg (E cherry) and 81.8 mg/kg (C orange), Mg contents ranged at the levels between 23.7 mg/kg (A apricot) and 65.4 mg/ kg (D orange). Generally Ca and contents of peach, orange and apricot juices that belong to A and D companies were determined at the high levels.
