| The differences of neutral aroma (including carotenoid degradation products, aromatic amino acids,
cembranoids and neophytadiene et al.) content of 4 different genotypes of flue-cured tobacco leaves in Guizhou were
studied by GC-MS method. The result showed that Bina1, Guiyan1 and Guiyan2 had higher neutral aroma than that of
K326. The total neutral aroma, carotenoid degradation products, aromatic amino acids, cembranoids and neophytadiene
content of Bina1 were higher than others. The carotenoid degradation products content of Binal was significantly higher
than Guiyan2, and neophytadiene content was significantly higher than K326. Guiyan1 and Guiyan2 had higher neutral
aroma content than that of K326, just because of their higher neophytadiene content. |
