Application to Identification of Sweet Potatoes by Solid Phase Micro Extraction (SPME)-GC/MS of Their Low Volatile Components

摘要

The volatile compounds from sweet potatoes were collected by solid phase micro extraction (SPME) and were analyzed by gas-chromatography mass spectrometry (GC/MS). The difference in a peak pattern of chromatograms was observed for various kinds of sweet potatoes. Possibility to identify a breed and a production district of sweet potatoes by the chromatograms obtained by SPME-GC/MS was examined.
