Abstract: The products of 1-carboxyethylamino-1-deoxy-D-fructose pyrolyzed in helium at 300, 500 and 800℃ were studied with an online pyrolysis gas chromatography-mass spectroscopy.The results showed that:1)the pyrolytic products varied with pyrolytic temperatures, the higher the temperature, the more the number of pyrolytic products;2)the major pyrolytic products were heterocyclic compounds, such as pyrazine, methylpyrazine, pyridine, furanone, pyrazole, pyrrole, pyranone, and etc., all of which are key aroma components in cigarette smoke.
