Abstract

We studied for the chemical characterizations of the charred residues obtained from the ancient potteries in the Proto-Three Kingdom period from archaeological sites in Joong-do, Chuncheon. Organic components of the charred residues were extracted and analysed using mass spectrometry and infrared spectroscopy. Lipid profiles from these samples were not identified in gas chromatography-mass spectrometry. Bulk stable isotope analyses of charred residues was used to infer an average values of the foods prepared. The average carbon isotope values (${\delta}^{13}C$) of the residues are $-14.7{\pm}2.8$‰ (ranging from -8.7‰ to -18.4‰, n=9), and nitrogen isotope values (${\delta}^{15}N$) are $6.2{\pm}1.1$‰ (ranging from -4.4‰ to -7.6‰, n=9). This is the first approach to analyse charred residues using stable isotopic method in Korea. Charred food residues on the interior surface of archaeological pottery can provide valuable information about pottery use and dietary habits of its population.

춘천 중도 유적에서 출토된 원삼국시대 경질무문토기 내부의 탄화된 물질에 대한 화학적 분석을 실시하였다. 가스크로마토그래피-질량분석과 퓨리에변환적외선분광분석을 이용하여 부착물에서 유래한 유기물의 정성분석을 수행한 결과, 지방산, 스테롤 등 지방성분이 검출되지 않았다. 탄소와 질소 안정동위원소 분석 결과 부착물을 구성하고 있는 탄소 안정동위원소 비는 평균 $-14.7{\pm}2.8$‰ (-8.7‰~-18.4‰, n=9), 질소 안정동위원소 비는 평균 $6.2{\pm}1.1$‰(-4.4‰~-7.6‰, n=9)로 나타났는데 이 결과는 부착물이 조리된 음식물에서 유래되었음을 추정할 수 있는 과학적 근거라고 할 수 있다. 본 연구결과는 안정동위원소 분석을 조리용 토기 내 탄화된 잔존물 분석에 적용한 국내 첫 사례로서 당시의 토기 용도와 식생활 습관에 대한 중요한 정보를 제공할 것으로 기대된다.
