ABSTRACT
OBJECTIVE:
To investigate the contamination of 2-chloropropanol esters and 3-chloropropanol esters in commercial edible vegetable oils in Shandong Province, and to assess the dietary 3-chloropropanol esters exposure and the health risk of intaking 3-chloropropanol esters.METHODS:
From 2016 to 2020, 406 individually packaged edible vegetable oils were collected from stores and farmers' markets in 16 prefecture-level cities in Shandong Province. According to the 2016 National Food Contamination and Harmful Factors Risk Monitoring Manual, using gas chromatography-triple quadrupole tandem mass spectrometry detection, isotope internal standard method for quantification, laboratory determination of 2-chloropropanol ester and 3-chloropropanol in vegetable oil ester content. Combined with population weight, oil consumption and monitoring data, the point assessment method was used to evaluate the exposure of residents in Shandong Province to 3-chloropropanol esters.RESULTS:
The detection rate of 3-chloropropanol ester was 92.4%(375/406), the concentration range was<limit of detection(LOD)-18.4 mg/kg, the median was 0.470 mg/kg, the average was 0.833 mg/kg, and the maximum value was 18.4 mg/kg in rice oil; the detection rate of 2-chloropropanol ester was 88.7%(360/406), the concentration range was <LOD-8.46 mg/kg, the median value was 0.204 mg/kg, the average value was 0.432 mg/kg, and the maximum value was 8.46 mg/kg in rice oil. The average exposure of each age group was less than the tolerable daily intake, and the high-end exposure of the children(2-6 years old) and adolescents(7-10 years old) group was greater than the tolerable daily intake.CONCLUSION:
The contamination of chloropropanol esters of edible vegetable oil in Shandong Province from 2016 to 2020 is widespread, and the highest detection value appears in rice oil. Children(2-6 years old) and adolescents(7-10 years old) in high-risk situations ingest 3-chloropropanol esters present health risks.Palabras clave
