title: Sugars present in tobacco extracts.
abstract: The presence of fructose, glucose, sucrose, maltose, and isomaltose in commercial tobacco products was identified and quantitated. Gas-liquid chromatographic studies showed that these five types of sugar were present in the water-soluble extracts of pouch and plug chewing tobacco, yet only fructose and glucose were found in extracts of snuff and unprocessed natural tobaccos. The amount of sucrose present in pouch chewing tobacco was twice that in plug chewing tobacco. No detectable amount of sucrose was found in snuff or unprocessed natural tobaccos. The content of maltose and isomaltose was much less than the content of fructose, glucose, or sucrose. All unprocessed natural tobacco leaves studied as controls contained low amounts of fructose and glucose, and no detectable amounts of sucrose, maltose, or isomaltose. The larger amounts of fructose and glucose, and the additional sucrose, maltose, and isomaltose present in pouch and plug chewing tobaccos are probably added during the manufacturing process.
