Sodium benzoate and aspartame belong to food additives commonly added to processed foods frequently consumed by consumers. In line with risk analysis principles, exposure assessments of these food additives are necessary. Due to a lot of activities of the students and affordably cheap price of processed foods, frequent consume of these food products are expected, which probably increase the intake and exposure level of food additives, including sodium benzoate and aspartame. This research is aimed to obtain data on the exposure level of sodium benzoate and aspartame from consumption of processed foods in a student population, calculated as percentage of Acceptable Daily Intake (ADD. An exposure assessment study of sodium benzoate and aspartame in high school students at SMA Kemah Indonesia 2 (SMA KI 2) and SMK Bina Insan Mulia(SMK BIM) have been conducted using survey consumption data method (food records 24 hours) for 48 hours and food frequency questionnaire (FFQ), in which 185 students took part in the survey. Following the survey, high consumed processed food products could be identified and sodium benzoate and aspartame contained in those products were determined quantitatively by high performance liquid chromatography (HPLC) method. The results showed that high-consumed processed foods products were of 4 categories, i.e. cereal, bakery, beverages and snacks. Among those products, 2 products of instant noodle, 4 products of beverages and I product of snack were declared to contain sodium benzoate and aspartame. The concentration of sodium benzoate in the instant noodle 2 and 3, as well as tea beverage I and 2 were found to be 564.18, 1184.06, 256.05 and 540.29 mg/kg, respectively, while those of aspartame in snack l, soft drink l, as well as powdered soft drink 2 and 3 were 161.92, 140.46, 2241.05, 5314.37 mg/kg, respectively. Taking into account the concentration of sodium benzoate and aspartame and the consumption data of these processed food products, the average value of exposure of sodium benzoate was 0.72 mg/kg body weight (bw)/day, while that of aspartame was 0.23 mg/kg bw/day. Calculated as percentage of ADI value, the exposure of sodium benzoate was (ADI = 5 mg/kg bw/day) 14.41 %, while that of aspartame (ADI = 40 mg/kg bw/day) was 0.57%. The highest individual exposure for sodium benzoate was 5.71 mg/kg bw/day (114.20% of ADD, while that of aspartame was 2.33 mg/kg bw/day (5.83% of ADD. Based on these results, it was concluded that the exposure level of sodium benzoate and aspartame among the students of SMA Kemah Indonesia 2 and SMK Bina Insan Mulia were still below the ADI values-
