Analysis of Four Water-soluble Sugars and Their Relationship with Sensory Quality in Yunnan Produced Cigarettes

To investigate the sugar content characteristics of Yunnan produced cigarettes, four water-soluble sugars including fructose, glucose, sucrose and maltose in 40 samples were quantified by liquid chromatography with evaporative light-scatting detector. The results showed that the mean sugar contents from high to low were fructose, glucose, maltose and sucrose. The mean contents were 11.99%, 7.95%, 1.52% and 1.32% respectively, and the coefficient of variation were 10.52%, 17.38%, 19.40% and 19.00%, respectively. The contents of fructose and glucose were higher, sucrose and maltose were lower, and the difference between sucrose and maltose was not significant. The content of glucose was highly positively correlated with fructose and sucrose, and the correlation coefficients were 0.899 and 0.642. The contents of fructose, glucose and glucose increased with cigarette quality improving from type 4 to type 2, and decreased slightly in type 1, while the content of maltose decreased from type 1 to type 4.
