초록

유통 중인 생분해성 합성수지로 만들어진 식품용 기구 및 위생용품 50건을 대상으로 '식품용 기구 및 용기·포장공전'의 기준·규격을 검사하였다. PLA 재질의 유아식기 1건에서 '과망간산칼륨소비량'이 20 mg/L으로 기준치(10 mg/L 이하)를 초과하였고, 그 외 모든 시료에서는 포름알데히드, 납, 비소 등이 기준·규격 이하로 안전한 수준이었다. 또한 가정에서 유아식기를 소독하는 방법의 안전성을 조사하기 위해, PLA 재질의 유아식기(n=21)에서 반복적인 열탕소독과 자외선 조사에 따른 이행량의 변화를 조사하였다. 반복적인 열탕소독이 자외선 조사에 비해 포름알데히드와 비소의 이행량이 많았으나, 이행량은 매우 낮은 수준이었다. 그리고 유아(만 1-3세) 기준으로 계산한 포름알데히드와 비소의 일일추정섭취량(EDI)은 최대 6.0×10-4mg/kg b.w./day 및 1.3×10-1 ㎍/kg b.w./day였으며, 이는 일일섭취한계량(TDI, 0.15 mg/kg b.w./day) 및 잠정주간섭취허용량(PTWI, 9.0 ㎍/kg b.w./week)의 0.40% 및 10.42%로 낮은 수준임을 확인하였다. 따라서 현 국내에서 유통되고 있는 식품용 생분해성 합성수지제는 안전한 수준임을 확인하였다.

In this study, we investigated the migration level of items specified in the Korean Standards and Specifications for Utensils, Containers, and Packages (Ministry of Food and Drug Safety Notification) for 50 utensils and hygiene products made of biodegradable resins. Our results revealed that one Polylactide (PLA) baby tableware contained 20 mg/L in consumption of potassium permanganate, exceeding the standard of 10 mg/L or less. In all other samples, formaldehyde, lead (Pb), and arsenic (As) levels could be considered very safe and remained below the standard. Moreover, we tested the PLA baby tablewares (n = 21) for migration into a food simulant (4% v/v acetic acid) upon repeated elution at 100℃ for 30 min or UV irradiation for 2 h. We detected increased formaldehyde and As amounts at the repeated 100℃ treatment for 30 min compared to those upon repeated UV irradiation. However, the migration level was markedly low under both conditions. Furthermore, the Estimated Daily Intake (EDI) calculated on an infant-to-child basis from the formaldehyde and As migration at 100℃ for 30 min in the PLA sample was at the maximum value, i.e., 6.0×10-4 mg/kg b.w./day and 1.3×10-1 ㎍/kg b.w./day, corresponding to 0.40% and 10.42% of the Tolerable Daily Intake (TDI, 0.15 mg/kg b.w./day) and Provisional Tolerable Weekly Intake (PTWI, 9.0 ㎍/kg b.w./week), respectively. Therefore, in this study, we confirmed that biodegradable synthetic resins are safe to use for food.
