연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

본 연구는 국내 유통되는 액상 유제품에 함유된 17종의 과불화화합물 (PFCs) 함량에 대한 모니터링을 위해 수행되었다. 샘플을 액체-액체 추출을 통해 추출하고 LC-MS/MS로 정량 분석하였다. 시중에 유통중인 98개의 액상 유제품 샘플에서 PFCs의 모니터링을 진행하였으며 그 결과, PFTeDA를 제외한 16종의 PFCs가 검출되었다. 총 PFCs의 함량은 0.9037 ng/mL로 액상 우유에서 가장 높았으며, PFPeA, PFDS, PFHxA도 액상우유에서 0.1 ng/mL 이상의 농도 수준을 보였다. 미국과 이탈리아에서 수행한 연구와 비교했을 때 PFOA와 PFOS의 잔류 패턴은 유사한 것으로 나타났으며, 농도 수준은 0.1 ng/mL 미만이었다. 액상 유제품은 다양한 가공단계(살균, 혼합, 지방제거 등)를 거쳐 총 PFCs의 함량이 감소하는 것으로 보여 지며, 특히 짧은 탄소 사슬을 가진 PFCs가 크게 감소하거나 검출되지 않았다. 이는 식품 안전에서 원료의 PFOS와 PFOA의 잔류정도가 중요하다는 것을 의미한다.

Abstract AI-Helper 아이콘AI-Helper

This study was carried out to monitor the level of 17 perfluorinated compounds (PFCs) present in liquid milk products sold on the Korean market. The liquid milk samples were extracted via liquid-liquid extraction and analyzed by LC-MS/MS. Excellent linearity over the calibration range (r2>0.99), and...
