Abstract

To determine the trace level of synthetic and natural hormones in food, the improvement of official analytical method and new development of simultaneous determination of hormones were established. On the basis of developed analytical method, the background level of natural hormones and distribution of residual hormones were monitored in meat. Target hormones were six natural hormones such as estrogens ($17{\beta}$-estradiol, $17{\alpha}$-estradiol, estrone), androgens ($17{\beta}$-testosterone, $17{\alpha}$-testosterone), and gestagens (progesterone) and three synthetic hormones such as DES, zeranol, and taleranol. These hormones were analyzed by gas chromatographymass spectrometry. Newly developed multi-residue analysis method was applied for meat sample which were collected from market in the capital region and monitored the presence of residues of synthetic and natural steroid hormones. No residue of synthetic hormones were detected and endogenous level of progesterone was detected in cattle, pig and liver samples tested.

가축의 생산성 향상을 위해 투여될 수 있는 천연호르몬과 합성 호르몬제 등의 내분비계장애물질에 대하여 기존의 분석 방법을 개선 및 확립하고, 이를 토대로 국내에 유통 중인 육류 및 내장부위 중소간에 대해 호르몬 성분의 분포정도를 확인하였다. Estrogens ($17{\beta}$-estradiol, $17{\alpha}$-estradiol, estrone), androgens ($17{\beta}$-testosterone, $17{\alpha}$-testosterone), gestagens (progesterone)의 천연호르몬 6종과 합성호르몬 3종 DES, RALs (zeranol, taleranol)을 모니터링 대상 호르몬으로 GC-MS로 분석하였으며, 이로부터 호르몬의 background level을 측정하고, 상대적으로 호르몬제 등이 잔류될 수 있는 간 등의 장기에 대한 분포조사를 실시하였다. 전체 150건의 시료 중 합성 호르몬제는 검출되지 않았으며, 천연호르몬제는 내인성으로 존재하는 progesterone이 일반적인 농도 범위를 보였다.
