摘要
[目的]研究产地、等级、部位、醇化时间对烟叶木质素含量的影响.[方法]以河南地区98个烟叶样品为研究对象,采用氢氧化钠/尿素-稀硫酸法测定其木质素含量,研究产地、等级、部位和醇化时间对烟叶木质素含量的影响.[结果]随着烟叶等级的升高(烟叶部位由上到下),总木质素含量呈增加趋势;随着醇化时间的延长,总木质素含量呈缓慢增加趋势;产地、等级、部位对烟叶木质素含量影响较大,而醇化时间对烟叶木质素含量影响较小.[结论]该研究可为合理利用烟叶、改善烟草品质提供理论依据.
Abstract
[Objective]To investigate effects of producing area,grade,position,alcoholization duration time on the lignin content in tobacco leaves.[Method]The lignin content of 98 tobacco samples from Henan area were determined by sodium hydroxide/urea-dilute sulfuric acid method and the difference of their effects on lignin content were studied by variance analysis.[Result]With the increase of tobacco leaf rank(from top to bottom),the contents of total lignin increased;With the extension of alcoholization duration time,the lignin content showed a slow increasing trend;Producing area,grade,position had significant influence on the lignin content in tobacco leaves while alcoholization duration had a little influence.[Conclusion]The study can provide theoretical basis for the rational use of tobacco leaf and improving tobacco quality.
