摘　　要：为评价造纸法再造烟叶柔软度,考察不同厂家造纸法再造烟叶柔软度的差异及含水率对造纸法再造烟叶柔软度的影响,分析了质构仪不同参数条件对测定结果的影响,建立了质构仪测定造纸法再造烟叶柔软度的方法,采用该方法对不同样品进行了检测。结果表明:①质构仪法测定造纸法再造烟叶柔软度的最佳条件是:选用球形探头、预压速度为5 mm/s、下压速度为2 mm/s、下压距离为10 mm、上拉速度为25 mm/s,该方法日内(RSD,n=10)、日间(RSD,n=5)精密度分别为6.637%和3.237%;②国内外不同厂家造纸法再造烟叶柔软度存在较大差异;③造纸法再造烟叶含水率对柔软度有显著影响,含水率越高,其柔软度越大。In order to evaluate the softness of paper-making reconstituted tobacco(RT)and to investigate the differences in the softness of RT between different manufacturers and the influences of moisture content on the softness,a method based on texture analyzer was established and key parameters of the texture analyzer on the determination results were analyzed.The established method was used to test and evaluate different RT samples,and the results showed that:1)The optimal conditions of the texture analyzer for determining the softness of RT were spherical probe,pre-test speed 5 mm/s,pressing speed 2 mm/s,pressing distance 10 mm,and pulling up speed 25 mm/s.This method had good intra-day repeatability(RSD=6.637%,n=10)and inter-day repeatability(RSD=3.237%,n=5).2)There were significant differences in the softness of the RT samples from different domestic and foreign manufacturers.3)Moisture contents of RT significantly affected the softness,the higher the moisture content was,and the softer the RT was measured.
