摘要
A thermal desorption-gas chromatography-mass spectrometry technique was applied to 252 different Spanish saffron samples (from La Mancha and Teruel). The average safranal content made up of 60% of the volatile fraction of the saffron. All the chromatograms obtained showed an interval between 8 and 18 min (retention time of safranal +/- 5 min) in which the silhouette of the chromatographic peaks was similar in all the samples. Therefore this interval can be used as a "fingerprint." Two examples are given which demonstrate the ability to use this "fingerprint" to detect adulteration.
