Analysis of 3-MCPD and 1,3-DCP occurrence in mayonnaise: A probabilistic risk assessment of dietary exposure for Iranians.

Mayonnaise is a commonly used oil-in-water emulsion food product. Due to their toxicological properties/genotoxicity and carcinogenicity, chloropropanols' oral exposure has raised concerns over the past decade. The present study reports the occurrence level of free forms of 3-chloropropane-1,2-diol (3-MCPD) and 1,3-dichloro-2-propanol (1,3-DCP) in mayonnaise samples and the risk of oral exposure to these chemicals through consumption of the analyzed samples.
