Abstract

Antioxidants are used in the manufacturing of commercial food packages made of polyolefin plastic such as polyethylene and polypropylene for the purpose to delay the oxidation reaction of the polymer due to oxygen or traces of ozone in the atmosphere. Additives in plastics may be migrated from the packaging materials into foods, thereby presenting a potential health risk to the consumer. Therefore, it is necessary to determine migration level of antioxidants from food packaging materials to foodstuffs in order to take proactive management. In this study, we have developed a method for the analysis of 10 antioxidants, which are butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), Cyanox 2246, 425 and 1790, Irgafos 168, and Irganox 1010, 1330, 3114 and 1076, migrated from the food packaging materials into four food simulants for aqueous, acidic, alcoholic and fatty foods. The antioxidants were determined by reversed-phase high-performance liquid chromatograph-ultraviolet detector with 276 nm after solid-phase extraction with a hydrophilic-lipophilic balance (HLB) cartridge or dilution with isopropanol. The analytical method showed a good linearity of coefficient ($R^2{\geq}0.99$), limits of detection (0.11~0.41 mg/L), and limits of quantification (0.34~1.24 mg/L). The recoveries of antioxidants spiked to four food simulants ranged from 71.3% to 109.4%. The migrated antioxidants in this study were within the safety levels that resulted from the safety assessment by the estimated daily intake to the tolerable daily intake.

본 연구에서는 식품용 기구 및 용기 포장으로부터 식품유사용매로 이행되는 10종의 산화방지제(butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), Cyanox 2246, 425 and 1790, Irgafos 168, 및 Irganox 1010, 1330, 3114 and 1076)의 분석법을 확립하였다. 식품유사용매 중 물, 4% 초산, 50% 에탄올의 경우 hydrophiliclipophilic balance (HLB) 카트리지로 고체상 추출(SPE, Solid Phase Extraction)을 하였고, n-헵탄의 경우 이소프로필알콜로 희석하여 HPLC-UVD (276 nm)로 산화방지제의 이행량을 분석하였다. 확립된 분석법으로 위생백, 지퍼백, 우유팩, 주스팩, 가공식품용 포장지, 밀폐용기, 일회용기 등 국내 유통 폴리에틸렌(78건) 및 폴리프로필렌(122건) 재질의 식품용 기구 및 용기 포장 200건으로부터 식품유사용매로 이행되는 10종의 산화방지제 이행량 조사 결과, 총 78건의 폴리에틸렌 식품용 기구 및 용기 포장 중 5건에서 Irganox 1010이 ND~1.444 mg/L 검출되었고, 총 122건의 폴리프로필렌 식품용 기구 및 용기 포장 중 41건에서 Irganox 1010이 ND~3.106 mg/L, 28건에서 Irganox 1076이 ND~4.752 mg/L, 34건에서 Irgafos 168이 ND~3.635 mg/L 검출되어 총 3종의 산화방지제가 검출되었다. 검출된 Irganox 1010, Irganox 1076, Irgafos 168에 대해 일일추정섭취량(EDI)을 계산하고 일일섭취한계량(TDI)과 비교하여 위해도를 평가한 결과, 폴리에틸렌 재질 중 Irganox 1010은 TDI 대비 0.0067%, 폴리프로필렌 재질 중 Irganox 1010, Irganox 1076, Irgafos 168은 TDI 대비 0.0073%, 0.1800%, 0.0200%로 안전한 수준임을 확인하였다. 본 연구에서 확립된 폴리에틸렌 및 폴리프로필렌 식품용 기구 및 용기 포장 중 산화방지제 분석법 및 안전성 평가 결과는 앞으로 기구 및 용기 포장의 안전관리를 위한 과학적인 근거자료로 활용될 것으로 판단된다.
