The samples were collected by purposive random sampling. five samples were analyzed by qualitative test using resorcinol reagent and quantitative test with alkalimetric titration methods. The qualitative test showed that all  samples were positive for saccharin indicated by the changes of color turning green fluorescence. The level of saccharin in the samples ranged between 160 – 580 mg/kg of ingredients. The higest  levels of saccharin (580 mg/kg) was assayed in sample E, and the smallest level ( 160 mg/kg)was assayed in sample B and C. According to Permenkes no.722/Menkes/Per/IX/1988 concerning food additives, maximal saccharin levels allowed in soft drink was 300 mg/kg of ingredients or 5 mg/kg of body weight. Only one sample (sample E) exceeded the limit of maximal saccharin levels allowed in soft drink.
