Determination of Some Heavy Metals By Icpoes in The Dark Chocolate
This study was performed for the determination of some heavy metals in dark chocolate obtained from a local market in Burdur city at Turkey. In general, the chocolate was prepared with sugar, cocoa mass, cocoa butter, and genus and/or cocoa powder, flavourings, milk and/or milk powder, and permissible additive agents. The cocoa solids contents in the commercial dark chocolate can be ranged from 47% to 75% and the heavy metals may be found in the cocoa solids at trace level. Owing to this, the concentration of heavy metals should be determined in the chocolate to decide whether it is healthy or not? In this proposed study, some heavy metals such as arsenic (As) , bismuth (Bi), cadmium (Cd), cobalt (Co), copper (Cu), manganese (Mn), molybdenum (Mo), nickel (Ni), lead (Pb), antimony (Sb), vanadium (V) and zinc (Zn) were determined by Inductively Coupled Plasma Optical Emission Spectroscopy (ICPOES).
