Summary: Processed foods were analysed by high performance liquid chromatography with ultraviolet detection for benzoic acid (n = 555) and sorbic acid (n = 829). The results were used to evaluate the estimated daily intakes (EDIs) of these additives from the Korean diet. Benzoic and sorbic acid were detected in 9.4 % and 42.3 % of the food items, respectively. The benzoic and sorbic acid contents in all the processed foods were below the Korean maximum permitted levels of 2000 mg·kg-1 and 3000 mg·kg-1, respectively. EDIs of benzoic and sorbic acids for total consumers were 2.2 % and 0.6 % of the acceptable daily intakes (ADIs) stipulated by the Joint FAO/WHO Expert Committee on Food Additives (0–5 mg·kg-1·d-1 benzoic acid, 0–25 mg·kg-1·d-1 sorbic acid), respectively. EDIs of benzoic and sorbic acids for the high consumption group (90th percentile) were 26.1 % and 8.4 % of ADIs, respectively. The highest benzoic and sorbic acid intakes were found in the 3–6-year-olds at 7.2 % and 1.2 % of ADIs, respectively. Beverages were a major contributor to EDI of benzoic acid, and soybean paste, processed fish products and pickles were major contributors to EDI of sorbic acid.
