Detection and quantification of 3-Monochloropropane-1,2-diol (3-MCPD) in bread in modern Bakeries in Khartoum state

Abstract

This study was carried out for the detection and quantification of 3-Monochloropropan-1,2-diol(MCPD) in bread in modern bahries in Khartoum state.Twenty five samples (25) of bread were collected from different modern bakries of Khartoum (Khartoum, Khartoum bahari and Omdurman), they include, round bread (13) samples and toast bread (12) samples. The moisture content and oil content of samples were determined according to the AOAC method and the quantity of 3-MCPD by Gas Chromatograpy mas Spectrometry (GC-MS). 3-MCPD exposure for individual by body weight per day for adults and children was estimated. Moisture content in round bread ranged from 31.7% to 35.7%, and in toast bread from 28.2% to 33.6%. Oil content in round bread ranged from 0.7955% to 0.9894% and oil content in toast bread from 0.7684% to 1.005%. 3-MCPD was detected in round bread and toast bread with a concentration of 0.15493-1.05873ppm to 0.11334-0.59644ppm, in round and toast bread, which were lower than that of European Commission Scientific Committee for Food Standardization. Exposure of adults and children to 3- MCPD upon consumption of bread is estimated to be (0.015446-0.031277μg\kg)-(0.002397-0.014118μg\kg)-(0.018039-0.036528μg\kg) and (0.002799-0.016488μg\kg) for adult and children, respectively. These exposure levels do not constitute a health risk.
