RESEARCH PROJECTS Method development and validation – Determination of bisphenol-A (BPA) in commercially packaged beverages and infant formulas Developed a novel LC-MS/MS based method to determine BPA concentration in various food matrices. Validated the method in ten types of on ten most-widely consumed commercially packaged non-alcoholic beverages, infant formula products and food simulating solvents with satisfactory accuracy and precision. Method development and validation – Determination of nonylphenol in infant formula ingredients and products Developed a simple and robust sample extraction approach applicable for nonylphenol isomers quantitative analysis in various food matrices. Validated the method in infant formula products, milk powders, food oils and sugars with satisfactory accuracy and precision. Method development and validation – Determination of trimethylamine N -oxide (TMAO) in krill oil feeds and products Established a high through-put infusion nano-ESI-MS analysis method to determine the concentration of TMAO in krill oil feeds and products. The validation meet the method performance requirements.
