Method for characterizing distribution stability of finished product cut tobacco structure by using conventional chemical compositions

Abstract

The invention provides a method for characterizing distribution stability of a finished product cut tobacco structure by using conventional chemical compositions. The method comprises the following steps: sampling the finished product cut tobacco; performing determination of conventional chemical components, such as total sugar, reducing sugar, total nitrogen, total plant alkali, potassium, and chlorine; calculating average, standard deviation, coefficient of variation and stability factor of the six conventional chemical components of the cut tobacco sample; finally, the average value of thestability coefficients of the six conventional chemical components is calculated. The larger the average value is, the closer to 100%, the better the distribution stability of the cut tobacco structure is. The conventional chemical components with high contents in the cut tobacco are used as evaluation indices, in order to quantitatively, scientifically and reasonably evaluate the distribution stability of the tobacco structure; and the inherent chemical quality stability of the finished product cut tobacco and the blending uniformity of the 'three kinds of cut tobaccos' are objectively reflected, in order to provide reference basis for improving cigarette quality and optimal control.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for characterizing the structural distribution stability of finished shredded tobacco. Background technique [0002] Shredded tobacco structure mainly refers to the ratio of different lengths of shredded tobacco to the mass of different lengths after the shredded width is determined in the process of making shredded cigarettes. Tobacco structure is one of the important factors affecting the quality of cigarettes. The structure of shredded tobacco has a certain degree of influence on the filling value of shredded tobacco, the physical index of cigarettes and the amount of tar released. The structure distribution stability of finished shredded tobacco refers to the similarity of the shredded tobacco structure at different time points at the same sampling position during the process of air delivery of finished shredded tobacco to the cigarette making...
