Thin-Layer Chromatography 에 依한 市眼알사탕類의 置色料에 關한 考察

Study on the Detection of Ar하ficial Dyes in the Commercial Drops by Use of Thln-Layer Chromatography

A study was carried out to detect of illegal artificial dyes, and to confirm the used rate of illegal dyes in the production process of commercial drops (candy), from Dec. 10, 1972 to Feb. 10, 1973. 1n this study, it was used thin layer chromatography, the samples were divided into two groups, .group A of inscribed trade name and group B of not inscribed trade name. To contrast with group A and group B, 100 samples were randomly collected in the market places, 50 sampl~s from group A and 50 samples from group B. The following conclusions were obtained: 1) used rate of ilIegal dyes were 2% of group A and 9% of group B. 2) used rate of illegal dyes were 2 % of red, 2% of yellow, 1% of violet and 6% of green, not in blue. 3) used rate of iIIegal dyes 3% of Rhodamine B, 3% of Auramine and 6% of Light green S.F. Yellowish. 4) Out of 20 cases those used mixed dyes, only one case was confirmed as two iIIegal dyes, and 4 cases were used one i1Iegal dye.
