Survey of 2-ethylhexanoic acid in baby food.

Abstract

A solid-phase microextraction method was developed and used to perform a survey of 2-ethylhexanoic acid (2-EHA) in 63 samples of baby food from 13 European Union countries, as well as from Norway and Switzerland. The levels of 2-EHA did not exceed 3.4 mg kg(-1). The concentrations of 2-EHA in 53 samples (84%) were in the range between <0.1 and 0.5 mg kg(-1). Ten samples showed the presence of the compound in the range between 0.5 and 3.4 mg kg(-1). An exposure assessment showed that the intake of 2-EHA does not exceed the tolerable daily intake (TDI) for infants of 6-12 months of age except one occurrence when taking the worst-case food consumption data available and the highest level of contamination of the survey. In the other cases, the levels of 2-EHA are at 13-fold below the TDI.
