Abstract
Contents of heavy metals in sugar products were estimated to provide a scientific basis for standardization of Korea Food Code of heavy metals. The contents of mercury (Hg), lead (Pb), cadmium (Cd), arsenic (As) and copper (Cu) were determined in 285 sugar product samples using a mercury analyzer, atomic absorption spectrophotometer, and inductively coupled plasma spectrometer. The values of heavy metals in sugar products $[minimum{\sim}maximum\;(mean),\;mg/kg]$ were as follows: $Hg,\;N.D.{\sim}0.006 (0.001);$ $Pb,\;N.D.{\sim}0.47 (0.03);$ $Cd,\;N.D.{\sim}0.06(0.005);\;As,\;N.D.{\sim}0.10(0.004);\;Cu,\;N.D.{\sim}1.89(0.15)$. These results show that metal contents of domestic sugar products are similar to those reported in other countries. Weekly average intakes of lead, cadmium, and mercury from sugar products were $0.004{\sim}0.1%$ of Provisional Tolerable Weekly Intake set by FAO/WHO Joint Food Additives and Contaminants Committee to evaluate the safeties of sugar products.
