Burley leaf tobacco extracts has been heated at loot for 2 hours and changes in non-volatile fructosazines and volatile components were investigated. Major changes for the heat treatment with corn syrup of burley leaf tobacco extracts were as follows, increases in the contents of 2,5-deoxyfructosazine and 2,5-fructosazine that is produce for the heating reaction of sugar and ammonia, production of pyraEine compounds, such as 2,6-dimethyl pyrazine,2,4-dimethyl pyrazine, ethrnyl pyrazine, methylethyl pyraxine, trimethyl pyrazine, 2-ethenyl-5-methyl pyrazine, 2-acetyl parazine and 2-acetyl-3-methyl pyrazine, increases in the content of furfuryl alcohol derived from sugar degrad ation, production of 2,5-dimethyl-4-hydroxy-3(2H)-furanone and 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one derived from thermal degradation of Amadori compounds.
