Research on Predominant Volatile Compounds of Grass Carp Meat

摘要

In this paper, the dorsal meat of grass carp was used as research object. The volatile compounds of grass carp were extracted and concentrated by headspace solid phase micro-extraction (HS-SPME). Then the volatiles were identified by gas chromatography-mass spectrometry (GC-MS). The results showed that SPME-GC-MS was effective to analysis of the volatiles in grass carp meat. According to GC-MS, 42 volatile compounds were detected in dorsal meat of grass carp. The volatile components are mostly carbonyl compounds and alcohols, and the relative contents are 95.74%. The method of odor activity value was applied to determine predominant volatile components of grass carp. There are 12 predominant components were determined in dorsal meat of grass carp, including: 1-Octen-3-ol, 2,6-Nonadienal, Nonanal, (E,E)-2,4-Decadienal, (E,Z)-2,4-Decadienal, Hexanal, 2-Nonenal, Octanal, 2-Decenal, Heptanal, Heptanol and 2-Octenal etc. The study will enrich the theoretical knowledge of flavor chemistry.
