Abstract:

Using the method of variance analysis, the change rule of chemical component of tobacco in aging was studied. The results showed that, with variance analysis, the significance of change of tobacco chemical component content in aging can be given, and the time area of fast and slow change can be distinguished. The variance analysis results showed that, in 16 kinds chemical components studied, 13 kinds had changed significantly in aging and their time area of fast change are usually than 18 months, these chemical components are the total sugar, reducing sugar, nicotine, total nitrogen, protein, hydroxyproline, polyphenol, carotenoids, starch, pectin, volatile fatty acids, volatile alkaloid and pH.
