摘要:

采用顶空-固相微萃取-气质联用法对腌制麻竹笋的挥发性成分进行分析,并比较了50/30μm DVB/CAR/PDMS萃取头和75μm CAR/PDMS萃取头对腌制麻竹笋的挥发性成分的萃取差异。结果表明:从腌制麻竹笋中共鉴定出57种挥发性物质,主要包括20种醛类、5种酮类、11种醇类、3种酸类、4种酯类、2种酚类、6种芳香烃类、6种其他类,其中主要的挥发性成分有4-甲基-苯酚、苯酚、苯甲醛、己醛、壬醛、2-庚烯醛、2,3-丁二醇、1-辛烯-3-醇、芳樟醇、乙酸、柠檬烯、环庚烷腈等。50/30μm DVB/CAR/PDMS萃取头比75μm CAR/PDMS萃取头多鉴定出12种挥发性成分,包括醛类2种、酮类1种、酸类2种、酯类3种、芳香烃类4种。

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.
