Assessment of flavour volatiles in vegetables - from comprehensive to rapid methods
Product monitoring needs rapid methods for analysing flavour in vegetables. Besides reducing sample preparation time, the acceleration of the gas chromatographic cycle becomes important. A mass spectrometric sensor was tested for dis-crimination of tomato cultivars and compared with gas chromatography/mass spec-trometry using complete separation of volatiles. Coupling this sensor with solid phase microextraction (SPME) seems to provide an efficient method of pattern rec-ognition analysis for flavour differences in vegetables based on mass fragment analysis of aroma volatiles.
