- Abstract
3-Monochloropropane-1,2-diol (3-MCPD), 2-monochloropropane-1,2-diol (2-MCPD) and 2,3-epoxy-1-propanol (glycidol), in their free form or esterified to fatty acids, are food contaminants formed during the refinement of oils and fats. We conducted a survey to quantify the levels of these compounds in 130 food items, in order to assess the exposure to them in food and the consequent health risk for consumers. Food samples, including infant formula, were analysed by gas-chromatography mass spectrometry with the indirect method, and we used the latest open access food consumption database for the Italian population for a probabilistic assessment of exposure. We adopted an in silico approach to fill the gap for the toxicity of 2-MCPD. The occurrence values for the three contaminants in food were in most cases lower than or comparable to those reported in previous surveys. Exposure assessment for the most exposed individuals (95
th percentiles of consumers only) of different age groups, gave values below the tolerable daily intake recommended by the European Food Safety Authority for 3-MCPD and below the simulated or predicted toxicity thresholds for 2-MCPD, indicating a negligible risk due to dietary exposure to these contaminants. For glycidol, however, estimated exposure indicated a non-negligible increase in cancer risk, and a margin of exposure <25,000 for younger population groups, indicating a potential health concern., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.
