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 (17β-estradiol, 17α-estradiol, estrone), androgens (17β-testosterone, 17α-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.
