초록

국내 유통 중인 콜라겐 제품 120건을 대상으로 중금속 4종(납, 카드뮴, 비소, 수은) 함량에 대해 조사하였다. 수은은 금아말감화법을 이용한 수은분석기로 분석하였고 납, 카드뮴, 비소는 ICP-OES를 이용하여 분석하였다. 검사 결과 납의 평균 함량은 0.097±0.055 mg/kg이었고 건강기능식품, 기타가공품, 음료류, 과·채가공품에서 각각 평균 0.108±0.052mg/kg, 0.084±0.053 mg/kg, 0.131±0.047 mg/kg, 0.149 mg/kg 농도로 검출되었다. 카드뮴의 평균 함량은 0.026±0.011 mg/kg이었으며 검출된 제품은 모두 건강기능식품이었다. 비소의 평균 함량은 0.097±0.048 mg/kg이었고 건강기능식품, 기타가공품, 과·채가공품에서 각각 평균 0.091±0.055 mg/kg, 0.133 mg/kg, 0.086 mg/kg 농도로 검출되었다. 수은의 평균 함량은 0.0025±0.0016 mg/kg으로 건강기능식품, 기타가공품, 과·채가공품, 캔디류에서 각각 평균 0.0012 mg/kg, 0.0028±0.0018 mg/kg, 0.0013 mg/kg, 0.0031 mg/kg 농도로 검출되었다. 중금속 기준·규격이 있는 음료류(납 0.3 mg/kg, 카드뮴 0.1 mg/kg) 및 캔디류(납 0.2 mg/kg)는 모두 기준 이하로 검출되어 적합하였다. 기준·규격이 없는 제품도 국내외 식품의 중금속 기준과 보고된 식품 중금속 함량과 비교하였을 때 비교적 안전한 수준이라고 판단되었다.

This study was conducted to estimate hazardous heavy metal content, including lead (Pb), cadmium (Cd), arsenic (As) and mercury (Hg) in 120 collagen products currently marketed in Korea. Hg concentration was analyzed by a gold amalgamation method using a mercury analyzer, while concentrations of Pb, Cd, and As were analyzed by ICP-OES. The average Pb concentration was 0.097 mg/kg. For comparison, respective average concentrations were 0.108 mg/kg, 0.084 mg/kg, 0.131 mg/kg, and 0.149 mg/kg in functional health foods, other processed products, beverages, and fruit/vegetable processed products. The average concentration of Cd was 0.026 mg/kg. All products in which Cd was detected were functional health foods. The average concentration of As was 0.097 mg/kg, with respective average concentrations of 0.091 mg/kg, 0.133 mg/kg, and 0.086 mg/kg in functional health foods, other processed products, and fruit/vegetable processed products. The average Hg concentration was 0.0025 mg/kg, with respective average concentrations of 0.0012 mg/kg, 0.0028 mg/kg, 0.0013 mg/kg, and 0.0031 mg/kg in functional health foods, other processed products, fruit/vegetable processed products, and candies respectively. Heavy metal levels in beverages and candy products with set heavy metal standards were below the set standards. Even products without regulatory standards were found to be relatively safe compared with heavy metal standards set for domestic and foreign foods.
