Abstract:

The volatile compounds of pickled Ma bamboo shoots were analyzed by headspace solid phase micro-extraction
(HS-SPME) coupled with GC-MS. The extraction efficiencies of 50/30 μm DVB/CAR/PDMS SPME fiber and 75 μm
CAR/PDMS SPME fiber were compared for volatile compounds from pickled Ma bamboo shoots. Results indicated that
57 volatile compounds including 20 aldehydes, 5 ketones, 11 alcohols, 3 acids, 4 esters, 2 phenolic compounds, 6 aromatic
hydrocarbons and 6 others were identified. The major volatile components in pickled Ma bamboo shoots were 4-methylphenol,
phenol, benzaldehyde, hexanal, nonanal, 2-heptenal, 2,3-butanediol, 1-octen-3-ol, linalool, acetic acid, limonene and
cycloheptyl cyanide. Twelve new volatile compounds were extracted by DVB/CAR/PDMS fiber when compared with CAR/
PDMS fiber, including 2 aldehydes, 1 ketones, 2 acids, 3 esters and 4 aromatic hydrocarbons.
