摘要：This study has been planned and carried out with a view to discover whether or not those synthetic dyes which are not allowed to be added into the jams, have already been added into the jams and also the quantities of synthetic dyes existing in the puddings, can dies and granulated powder drinks which are permitted to be added with such dyes, are also compatible with the quantities specified by the Food Additives Regulation in Turkey. All samples used during this study, have been obtained from sources of Ankara market and totally 263 samples have been analysed. The extraction process of all samples, has been performed through the wool coloring method. The extracted dyes have been subjected to the qualitative analysis through the TLC (Thin Layer Chromatography) Method. At the end of qualitative analysis performed on the jams and puddings, it has not been possible to handle the quantitative determinations since no synthetic dye has been found. The samples of candy and granulated powder drinks, in the contents of synthetic dyes, have determined the use of a single C18 Sep-pak Cartridge and also the spectrophotometric methods. Among these synthetic dyes, the average level of Ponceau 4R has been found as 117.45±19.37 mg/kg, in the candies, 294.79±26.21 mg/kg for the granulated powder drink. The values were not suitable by the Food Additives Regulation. The average level of tartarazine has been determined as 147.77±20.51 mg/kg and 201.19±37.16 mg/kg respectively for candies and granulated powder drinks. The levels of tartrazine were in maximum values. The average levels of Sunset Yellow F.C.F. have been found as 174.58±31.54 mg/kg and 293.31±24.19 mg/kg respectively for granulated powder drinks. The values also had been found over dose. The average level of azorubine, has been determined as 181.22±20.22 mg/kg for candies and found compatible with those specified by the Food Additives Regulations. The average value of mixed dyes existing in the granulated powder drinks, has been determined as 241.44 mg/kg. This value was over the value specified by the Food Additives Regulation.
