The impact of infant formula production on the concentrations of 3-MCPD and glycidyl esters
ABSTRACT Fatty acid esters of 3-monochloropropanediol (3-MCPD), 2-monochlorpropanediol (2-MCPD), and glycidol are process-induced chemical contaminants found in refined vegetable oils. Due to their toxicological properties, there is potential concern regarding exposure to these compounds, particularly for formula-fed infants where refined edible oils are the primary fat source in commercial infant formulas. In order to assess exposure, 55 commercial oil samples, specifically intended for use in infant formula, were collected in 2015 from various infant formula manufacturers in the United States and analysed using a LC-MS/MS direct detection method. At the time of collection, there were no validated methods for the analysis of MCPD and glycidyl esters in infant formula. Therefore, analysis of these commercial oil samples served as an alternative for confirming the presence of these ester contaminants in infant formula. Bound 3-MCPD and glycidol concentrations in these oils ranged from below the limit of quantitation (
