Objective To analyze the concentration and source of benzoic acid in rice wine and evaluate the health risk of dietary benzoic acid intake from rice wine among adult consumers in China. Methods 231 samples of rice wine and 15 samples of raw materials were collected from five main rice wine production areas in China, including Shandong, Zhejiang, Jiangsu, Fujian and Shanghai; the content of benzoic acid and its precursors were determined by high performance liquid chromatography; the sources of benzoic acid in rice wine were analyzed by the benzaldehyde and phenylalanine simulation test and the real sample acceleration test; the benzoic acid intake among adult consumers was evaluated by simple distribution assessment method. Results In all rice wine samples, the detection rate of benzoic acid was 99.13%(229/231), the concentration range of benzoic acid was ND (not detectable)-37.00 mg/L, and the average was 2.28 mg/L. In 98 end products, the detection rate of benzoic acid was 100.00%(98/98), the concentration range of benzoic acid was ND-1.60 mg/L, and the average was 0.52 mg/L; in 133 base wine samples, the detection rate of benzoic acid was 98.50%(131/133), the content range of benzoic acid was ND-37.00 mg/L, and the average was 3.58 mg/L. The result of source analysis showed that the benzoic acid in rice wine mainly came from raw materials, degradation of phenylalanine and oxidation of benzaldehyde. Exposure assessment result showed that the average exposure of benzoic acid for rice wine consumers in China was 0.001 mg/kg BW, accounting for 0.02% of the acceptable daily intake(ADI); and the 95th percentile was 0.005 mg/kg BW, accounting for 0.1% of the ADI. Conclusion The detection rate of benzoic acid in rice wine was high but the concentration was low. Source analysis result indicated that benzoic acid in rice wine mainly came from raw materials, degradation of phenylalanine and oxidation of benzaldehyde; the health risk of benzoic acid exposure to adult rice wine consumers in China was low.
