Concentration ofselected trace metals were estimated using atomic absorptionspectrometer. Results obtained from study show high concentration ofiron and manganese in all the sweets. High concentration of iron maybe due to the cooking utensils rich of iron. Use of manganese inalloys may be responsible of such high concentration of manganese insweets. Metal load in sweets of all shops seem in the limits offered byRDA for respective metals. All food colors used in making sweets arepermitted food colors, because sweets show no abnormal metal load.
