초록

본 연구는 우리나라 식품공전의 당류 중 중금속 함유량을 파악하여 식품공전 제 개정시 과학적 기초자료로 활용하고자 수행하였다. 1999년에 총 285건의 당류에 대하여 ICP, AAS 및 Mercury analyzer 등을 이용하여 납 등 중금속함량을 측정하였으며 그 결과는 다음과 같다. [최소${\sim}$최대(평균), mg/kg]; Hg: 불검출${\sim}0.006(0.001)$, Pb: 불검출${\sim}0.47(0.03)$, Cd: 불검출${\sim}0.06(0.005)$, As: 불검출${\sim}0.10(0.004)$, Cu: 불검출${\sim}1.89(0.15)$. 본 조사결과는 외국의 모니터링 결과와 유사한 것으로 나타났다. 또한 당류를 통한 우리나라 국민의 납, 카드뮴, 수은의 섭취량은 FAO/WHO에서 중금속 안전성 평가를 위해 정한 PTWI의 $0.004{\sim}0.1%$로 안전한 수준이었다.

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.
