Tartrazine is a synthetic dyes which classified into for foods and bevereges the use of tartrazine must be conducted in accordance with the applicable regulations. The monitoring of tartrazine is necessary for required to ensure the safety of the produck. Qualitatif analysis using thin layer chromatography (TLC) method white mobile phase isopropanol:ammonia 25% (4:1). Thin layer chromatogrphy result showed that 7 in 11 sample contain tartrazine. While fot The quantitative analysis using spectrophotometry visible. Result method analysis obtained value of presicion was 0,157 %. persent value of mean recovery ataccuration test method were to 100,264 %. Liniaritas showed with coefficient of correlation value r2 = 0,997. Limit of detection and limit of quntitation of this research was 2,0376 ppm and 6,7922 ppm. It was found that concentration of tartrazine lowest levels in sample F 37,92 mg/L and the highest levels in sample C 63,605 mg/L. Based on the level which is producted shows that the sample which is contained tartrazine the level is not more than the standard 70 mg/Lrn
