The Effect of Probiotic Bacteria on the Reduction of ۳-Monochloropropane-۱,۲-Diol (۳-MCPD) in Powdered Infant Formula

Background & Objectives: ۳-Monochloropropane-۱,۲-diol (۳-MCPD) is a chemical contaminant found in many food products, including infant formulas. Given the vital contribution of milk and its products to the human diet, particularly for children, the presence of ۳-MCPD in dairy products poses a significant public health concern. Therefore, it is crucial to explore natural compounds for ۳-MCPD removal. This study investigates the effect of probiotic microorganisms (Lactobacillus plantarum, Lactobacillus murinus, and Yarrowia lipolytica) on reducing ۳-MCPD levels in infant formula containing various ۳-MCPD concentrations. Materials & Methods: L. plantarum, L. murinus bacteria, and Y. lipolytica yeast were prepared as active cultures. Subsequently, various ۳-MCPD concentrations were added to the infant formula, and the effect of the bacteria and the yeast on ۳-MCPD reduction was investigated using gas chromatography with flame ionization detection (GC-FID). Results: L. plantarum, L. murinus, and Y. lipolytica demonstrated the ability to reduce ۳-MCPD levels in the infant formula at different concentrations and contact times. L. plantarum and Y. lipolytica were found to be more effective in reducing ۳-MCPD in the infant formula compared to L. murinus. Conclusion: The results indicate that probiotic bacteria can effectively mitigate the toxic effect of ۳-MCPD. These findings have potential applications in the food industry, particularly in dairy products.
