摘要
为建立一种客观评价造纸法烟草薄片脆性的方法,采用质构仪对不同含水率的1#造纸法烟草薄片样品进行撕裂测试和拉伸测试,分析测试结果与样品含水率的关系;采用质构仪对国内不同种类（1#～4#）造纸法烟草薄片进行撕裂测试,分析该方法的准确性.结果表明：无论撕裂测试是纵向还是横向,样品的正峰个数与含水率的相关系数（R^2）最高,分别为0.938 0、0.954 8,说明撕裂测试时正峰个数能够表征造纸法烟草薄片的脆性;撕裂测试时国产造纸法烟草薄片的正峰个数与其手感脆性相对应,该方法能够准确评价和区分各类国产造纸法烟草薄片的脆性.
The aim of this work was to establish a method for the evaluation of paper-process reconstituted tobacco（RT）fracturability,Texture Analyzer（TA.XT plus,SMS,UK）was used to carry out tearing and tensile tests of RT,the relationship between the peak number,average tearing force,the first peak of the slope,B value and water ratio were analyzed;Varies of samples from domestic was analyzed to assess the accuracy and applicability of the tearing test method.It shows that the change of peak number matches well with water ratio,either transverse or longitudinal,R^2 reaches 0.938 0and 0.954 8respectively.Tearing test corresponding to the fracturability of RT evaluated by feelings could accurately and distinguish evaluate many kinds of domestic RT with their fracturability.
