Fatty acid esters of 3-monochloro-1,2-propanediol (3-MCPD), 2-monochloro-1,3-propanediol (2-MCPD), and glycidol are process-induced chemical contaminants found in refined edible vegetable oils. Formed during the deodorization step of the refining process, these compounds are considered potentially carcinogenic and/or genotoxic, making their presence in edible oils and processed foods containing these oils a potential health risk. Over the last 15 years, research efforts have focused on the development of methods for the quantitation of these contaminants in oils, infant formulas, and other complex food matrices in an effort to estimate levels of exposure. More recently, EU regulations for maximum bound glycidol concentrations in edible oils and infant formulas have highlighted the need for accurate analytical methodologies. This presentation will discuss current analytical methods for the analysis of these contaminants, including methodologies developed in our laboratory at the U.S. Food and Drug Administration (FDA). In addition, the results of several occurrence studies conducted in our laboratory, which show a wide range of bound 3-MCPD and glycidol concentrations across a variety of edible oils, infant formulas, and food products, will be presented. <br/>
