摘要
研究了福建和云南烤烟片烟在醇化过程中还原糖、淀粉、总氮、烟碱、挥发碱、挥发酸含量及pH值的变化。结果表明 ,片烟的还原糖、烟碱、挥发碱含量及pH值均随着醇化的进行呈持续降低趋势 ;挥发酸含量则逐渐增加 ;总氮含量无明显变化 ;淀粉含量在醇化过程中的变化与供试片烟的产地、等级(配方 )有关。
The changes of reducing sugar, starch, total nitrogen, nicotine, total volatile bases, total volatile acids and pH values of flue-cured tobacco strips grown in Fujian and Yunnan Provinces of China were studied during aging. The results showed that: 1) the contents of reducing sugar, nicotine, total volatile bases and pH value of the strips were continually decreased with the proceeding of aging, while the total volatile acids were gradually increased; 2) total nitrogen was rarely affected; and 3) the changes of starch contents in the strips during aging were related to the growing district and the grades of strips.
