Quantification of phytic acid in baby foods by derivatization with (trimethylsilyl)diazomethane and liquid chromatography-mass spectrometry analysis.

A robust and sensitive method for the determination of PA in baby foods has been developed by methyl esterification with (trimethylsilyl)diazomethane and using LC/MS/MS analysis. The established method showed good anti-interference and precision, and it has been applied for the determination of PA in various baby foods.
