Iftikhar Imam Naqvi, Qurat-ul-ain Saeed and M. Akhyar Farrukh    

Abstract: The study presented was concerned with the determination of level of iron, nickel, cobalt, copper, lead, manganese and cadmium in different sweets (Gulab Jamun, White Chum Chum, Colored Chum Chum, Khopre ki Mithai, Qalaqand, Bhashani Chum Chum, Basin ka Lado and Patesa) collected from selected shops of Karachi city. Concentration of selected trace metals were estimated using atomic absorption spectrometer. Results obtained from study show high concentration of iron and manganese in all the sweets. High concentration of iron may be due to the cooking utensils rich of iron. Use of manganese in alloys may be responsible of such high concentration of manganese in sweets. Metal load in sweets of all shops seem in the limits offered by RDA for respective metals. All food colors used in making sweets are permitted food colors, because sweets show no abnormal metal load.
