本研究自民國82年10月至83年5月間於全省各便利商店、超市及百貨公司抽購蜜錢及糖清果實類檢體193件，依據中國國家標準10889,N6185號中毛線染色之分離鑑別法予以檢驗，結果有142件檢出含著色劑。利用薄層層析法及高效液相層析法分離鑑定，經確認結果其中3件紅色話梅檢體檢出商品名為orange R (C.I. acid orange 14, C.I. 16100)之規定外色素，實驗證明該色素與ponceau 2G (C.I. 16100)相符，不合格率為總抽樣檢體之1.6%，但就紅色話梅而言，不合格率卻高達60%，並業已通知地方衛生機關列入經常抽驗項目。實驗證明薄層層析法之分離效果較濾紙層析法為佳，而高效液相層析法又可進一步確認薄層層析法之結果，故著色劑之再確認宜採薄層層析法及高效液相層析法加以鑑定。

One hundred and ninety three samples of syrupy fruits (44) and preserved fruits (149) were analyzed for coal tar dyes. Samples were assessed according to official methods and high performance liquid chromatography during a period from October 1993 to May 1994. The results confirmed that three "Hwamei" samples (1.6%) contained additives of orange R (C.I. acid orange 14, C.I. 16100) which violate the current approved standards. It also was identified as ponceau 2G. For identifying coal tar dyes, TLC was found to be a more sensitive method compared to PC, and HPLC was used to further confirm the results of TLC.
