摘要:

挥发性香气成分是块菌品质的重要指标,为探究不同品种块菌挥发性香气成分的差异,采用顶空固相微萃取结合气相色谱-质谱联用对挥发性成分进行分析,并采用相对气味活度值判定主体挥发性香气成分。结果表明:6 种块菌共鉴定出24 种挥发性成分,主要包括醇类、酮类、醛类、烯类等,6 种块菌中共有的挥发性成分为1-辛烯-3-醇、苯乙醛、反-2-辛烯醛。假凹陷块菌的主体挥发性香气成分为1-辛烯-3-醇和苯乙醛;夏块菌的主体挥发性香气成分为1-辛烯-3-醇、苯乙醛、反-2-辛烯醛、苯甲醛和己醛;印度块菌和会东块菌的主体挥发性香气成分为1-辛烯-3-醇;凹陷块菌的主体挥发性香气成分为1-辛烯-3-醇、苯乙醛、反-2-辛烯醛、己醛和3-辛酮;波氏块菌的主体挥发性香气成分为1-辛烯-3-醇、反-2-辛烯醛和3-辛酮。

Abstract:

The volatile aroma composition is an important indicator to evaluate the quality of truffle. In order to explore
the difference in volatile aroma composition among different species of truffle, the aroma components in truffle were
investigated and classified by headspace solid-phase microextraction (HS-SPME) combined with gas chromatographymass
spectrometry (GC-MS), and the key volatile aroma components were judged by the relative odor activity value. The
results showed that 24 aroma compounds were identified from 6 species of truffle, including alcohols, ketones, aldehydes
and alkene. Five flavor compounds including 1-octen-3-ol, phenylacetaldehyde and (E)-2-octenal were common to all
the truffle species investigated. The key volatile aroma components of Tuber pseudoexcavatum were 1-octen-3-ol and
phenylacetaldehyde; those of Tuber aestivum were 1-octen-3-ol, phenylacetaldehyde, (E)-2-octenal, benzaldehyde and
hexanal; those of Tuber indicum Cooke et Massee and Tuber huidongense was 1-octen-3-ol; those of Tuber excavatum were
1-octen-3-ol, phenylacetaldehyde, (E)-2-octenal, hexanal and 3-octanone; those of Tuber borchii were 1-octen-3-ol, (E)-2-
octenal, and 3-octanone.

Key words: Tuber, volatile aroma components, gas chromatography-mass spectrometry (GC-MS), key volatile aroma components, relative odor activity value (ROAV)
