Determination of aliphatic aldehydes as their thiazolidine derivatives in foods by gas chromatography with flame photometric detection.

A selective and sensitive gas chromatographic method for the determination of saturated and unsaturated aliphatic aldehydes in foods has been developed. After extraction of the sample with acetonitrile, aldehydes were converted into their thiazolidine derivatives by the reaction with cysteamine, and then measured by gas chromatography with flame photometric detection. The calibration curves for aliphatic aldehydes in the range 20-2500 ng were linear and the detection limits at a signal-to-noise ratio of 3 were ca. 4-100 pg injected. Aliphatic aldehydes in foods could be selectively determined by this method without any interference from coexisting substances. Overall recoveries of aldehydes added to food samples were 82-111%. Analytical results for the determination of aliphatic aldehydes in various food samples are presented.[1]
