Abstract

This study was conducted to evaluate the daily intakes of propyl gallate, EDTA (ethylenediamine tetra acetate), and erythorbic acid for average consumers by age group and the intake of high consumers ($95^{th}$ percentile) in Korea. The average intake of EDTA was $1.14{\mu}g/kg{\cdot}bw/day$, and 0.0% of the ADI (acceptable daily intake) established by JECFA (Joint FAO/WHO Expert Committee on Food Additives). The $95^{th}$ percentile intake of EDTA was $141.24{\mu}g/kg{\cdot}bw/day$ (5.6% of ADI). The average intake of erythorbic acid was $16.93{\mu}g/kg{\cdot}bw/day$, and the 3-6 year-old group had the highest consumption ($58.43{\mu}g/kg{\cdot}bw/day$), which was <1.0% of the ADI established by the EU (European Union). The $95^{th}$ percentile intake of erythorbic acid was $1,320.31{\mu}g/kg{\cdot}bw/day$ and 22.0% of the ADI. In conclusion, daily intakes of propyl gallate, EDTA, and erythorbic acid in Korea were at safe levels in all age groups and also in high consumers.

가공식품에 첨가된 몰식자산프로필(propyl gallate), 이디티에이 (ethylenediamine tetra acetate), 에리쏘르빈산(erythorbic acid)의 섭취 안전성을 평가하고자, 몰식자산프로필 함유식품 65 품목, 이디티에이 함유식품 121 품목, 에리쏘르빈산 함유식품 266 품목을 HPLC로 분석하여 그 함량을 모니터링 하고, 국민건강 영양 조사의 식이섭취량자료를 이용하여 몰식자산프로필, 이디티에이, 에리쏘르빈산의 국민평균섭취량 및 상위섭취량($95^{th}$ percentile)을 추정하였다. 몰식자산프로필은 건과류 2건에서만 0.1 ppm 검출되었을 뿐 다른 품목에서는 전혀 검출되지 않았고, 이디티에이는 총 시료의 47.1%의 검출율을 나타내었다. 이디티에이를 가장 많이 함유하고 있는 품목은 마요네즈로서 50.6 ppm이었고, 드레싱과 마가린에서도 각각 26.3, 14.1 ppm 검출되었으며, 이 세 식품 유형에서의 이디티에이 검출율은 전체의 약 40%에 달하였다. 에리쏘르빈산은 총 266개 품목 중 128개 품목에서 검출되어 48.1%의 검출율을 나타내었고, 검출율이 높은 품목은 건조저장육(67.5%), 소시지(51.9%), 햄류(40.7%)로 나타났다. 에리쏘르빈산의 평균 함량은 향신료가공품이 523.6 ppm으로 가장 높았다. 이디티에이의 국민 일일 평균 섭취량은 $1.14{\mu}g/kg{\cdot}body\;weight/day$(ADI 대비 0.05%)로 나타났고, 기여식품은 마요네즈, 드레싱, 햄버거, 마가린으로 나타났다. 연령별 섭취량은 29세 이하의 연령대에서 그 이상의 연령대 보다 많이 섭취하는 것으로 나타났는데, 그 양은 ADI 대비 0.1%에 불과해 매우 안전한 수준이었다. 이디티에이 섭취자 그룹 중 상위섭취자($95^{th}$ percentile 섭취자)의 섭취량은 $141.24{\mu}g/kg{\cdot}body\;weight/day$로 나타나, JECFA에서 설정한 ADI 대비 5.6%로 매우 안전한 수준이었다. 식품을 통한 에리쏘르빈산의 국민 평균 섭취량은 $16.93{\mu}g/kg{\cdot}body\;weight/day$로 나타났고, 섭취에 기여하는 식품은 햄, 소시지, 어육가공품, 빵류 이었다. 연령별로는 3-6세의 어린이들이 $58.43{\mu}g/kg{\cdot}body\;weight/day$로 가장 많이 섭취하는 것으로 나타났으나, EU에서 설정한 ADI와 비교해 볼 때 ADI의 1.0%로 매우 안전한 양이었다. 또한 에리쏘르빈산 섭취자 그룹 중 상위 $95^{th}$ percentile 섭취량을 추정한 결과 $1320.31{\mu}g/kg{\cdot}body\;weight/day$, ADI 대비 22.0%로 나타났다. 이상의 결과로 볼 때 한국인의 몰식자산프로필, 이디티에이, 에리쏘르빈산 섭취량은 모든 연령대에서 매우 안전한 수준이며, 상위 섭취자($95^{th}$ percentile 섭취자)의 섭취량 또한 안전하다는 것을 알 수 있었다.
