Objective To understand the pollution situation of new risk factors such as 3-chloropropanol ester (3-MCPDE), glycidyl ester (GE), dibutyl phthalate (DBP) and bis(2-ethylhexyl) phthalate (DEHP) in Camellia oleifera seed oil of Jiangxi Province, and make risk assessment. Methods The content of 3-MCPDE, GE, DBP and DEHP in 29 batches of Camellia oleifera seed oil were determined by gas chromatography-mass spectrometry, and the exposure risk was analyzed by dietary exposure assessment method. Results The content of 3-MCPDE in Camellia oleifera seed oil ranged from 0.11 mg/kg to 4.52 mg/kg, the detection rate was 75.86%, and the problem rate was 10.34%. GE content ranged from 0.13 mg/kg to 11.76 mg/kg, the detection rate was 72.41%, and the problem rate was 44.83%. The content of DBP ranged from 0.43 mg/kg to 12.90 mg/kg, and the problem rate was 34.48%. The range of DEHP content was 0.57-9.69 mg/kg, the detection rate was 55.17%, and the problem rate was 20.69%. The average exposure of residents to DBP, DEHP, 3-MCPDE and GE through edible oil tea seed oil ranged from 0.56 μg/(kg·BW) to 0.75 μg/(kg·BW), and the exposure risk of DBP, DEHP and 3-MCPDE ranged from 1.12% to 37.37%. The exposure risk of margin of exposure (MOE) of GE was 3948.94 for men and 3347.52 for women, with both MOE values being below 10000. Conclusion Camellia oleifera seed oil poses a certain risk of contamination with 3-MCPDE, GE, DBP and DEHP. The likelihood of human health hazards from DBP, DEHP, and 3-MCPDE intake through Camellia seed oil is very low for residents. However, greater attention shall be paid to the health risks associated with GE exposure.
