title: [Studies on rejected food yellow no. 5 (sunset yellow FCF) aluminum lake].
abstract: One out of two sunset yellow FCF aluminum lakes (Y-5Als) did not comply with the specifications in JSFA-VII in the official inspection of tar colors in fiscal year 2000. A sub-spot was detected in the paper chromatography test. This rejected sample was analyzed by HPLC for the subsidiary color, raw materials and intermEdiates in Y-5. The sub-spot was identified as sulfanilic acid azo R salt color, and its content was estimated at 4.5% as the content of Y-5 in Y-5Al being 100.0%.
