Abstract

This study was conducted to survey levels of heavy metals, benzopyrene and mycotoxins in teas purchased from online markets, supermarkets, and traditional markets in Gwangju, Korea. We examined the arsenic, cadmium and lead content in heavy metals. We also tested for benzo(a)pyrene, which is classified as a carcinogen. In addition, we tested for the mycotoxins aflatoxin (AFB1, AFB2, AFG1, AFG2), ochratoxin A (OTA), fumonisin (FUB1, FUB2), and zearalenone (ZON). According to our results, heavy metals were detected within the allowable range (below 5.0 mg/kg for lead) and all samples met with the standards for tea as presented in the Korean Food Code. The Benzo(a)pyrene showed a detection rate of 12.8% in 16 of 125 samples and mycotoxins showed 23.2% in 29 of 125 samples. However, safe levels regarding benzo(a)pyrene and mycotoxin in tea were not ascertainable since the standards are not set in the Korean Food Code.

2018년 10월부터 2019년 10월까지 광주지역의 대형마트(50건), 재래시장(25건) 및 온라인(50건)에서 구입한 보리차, 옥수수차, 결명자차, 둥글레차, 옥수수수염차 등 침출차 총 125건을 대상으로 중금속, 벤조피렌, 곰팡이독소 함량 조사를 통해 오염실태를 평가하였다. 중금속 중 As, Cd, Pb 함량을 검사하였으며, benzopyrene은 발암물질로 분류된 benzo(a)pyrene의 함량을 조사하였다. 그리고 곰팡이독소는 aflatoxin (AFB1, AFB2, AFG1, AFG2), ochratoxin A (OTA), fumonisin (FUB1, FUB2), zearalenone (ZON)의 함량을 검사하였다. 「식품공전」에 제시된 침출차의 규격과 비교해 보았을 때 중금속 함량은 기준이 설정된 범위(Pb 5.0 mg/kg 이하) 내에서 검출되어 모두 적합하였고, benzo(a)pyrene은 125건 중 16건의 시료에서 12.8%의 검출률을 나타내었으며, 곰팡이독소는 125건 중 29건의 시료에서 23.2%의 검출률을 나타내었다. 하지만 현재 우리나라 「식품공전」에서는 침출차의 벤조피렌, 곰팡이독소 기준규격이 정해져있지 않아 이에 대한 안전성 여부는 확인하기 어려웠다.
