- 摘要:
- 为明确香椿不同挥发性物质及组成成分,以曲靖农家香椿为试验材料,采用顶空固相微萃取法测定香椿挥发性物质成分并进行分类。结果表明,共检测出5类27种挥发性物质,分别为烷烃类、萜烯类、酯类、含硫化合物和噻吩类;曲靖早熟农家香椿的挥发性物质主要由萜烯类组成,而使香椿具有特异性气味的成分为具有蒸煮香椿味的2-巯基-3,4-二甲基-2,3-二氢噻吩,具有洋葱味、硫磺味的2,4-二甲基噻吩和3,4-二甲基噻吩这几种特殊物质。
- Abstract:
- In order to identify different volatile substances and components of Toona sinensis, in this study, using Toona sinensis in Qujing Area as the experimental material, the volatile components of Toona sinensis were determined by headspace solid phase microextraction and classified. The results showed that a total of 27 volatile substances were detected by classifying the volatile substances measured, namely alkanes, terpenes, esters, sulfur-containing compounds and thiophenes; The volatile substance components of early maturing Toona sinensis in Qujing Area were mainly composed of terpenes, while the substances that make toon have a specific odor were 2-mercapto-3, 4-dimethyl-2, 3-dihydrothiophene with the taste of boiled toon, with onions, sulfur flavors 2, 4-dimethylthiophene and 3, 4-dimethylthiophene, which provide a theoretical basis for the study of the main volatile substance components of early maturing farmhouse toon.
