肉鸭经松香脱毛后表皮松香残留的薄层色谱检测研究

Thin-layer Chromatography Method for Test of Rosin Residue in Skin of Rosin-unhaired Meat Duck

为建立鸭表皮残留松香的检测方法,以模拟鸭厂生产条件对肉鸭进行松香脱毛处理、取样,采用固相萃取(SPE)法对样品进行纯化与富集,以枞酸为松香的标记物质,通过薄层色谱法(TLC)对样品进行鉴定。结果表明:此方法能在鸭表皮检出残留的松香。

A method for detecting the residual rosin in the skin of rosin - unhaired meat duck was established. The meat ducks were unhaired by using rosin under the simulative duck factory conditions, and the unhaired meat ducks were sampled. SPE method was used for the purification and enrichment of the samples. Thin - layer chromatography （ TLC ） was used for sample identification through taking abietie acid as rosin marker. The results showed that the method could be used for the identification of residual rosin in duck epidermis.
