卷烟烟丝结构分布及其与物理质量的关系
Cut tobacco structure distribution and its relation with physical quality
摘要
Abstract
[Objective]Distribution of different-grade cut tobacco structure and its effects on cigarette quality were studied in order to provide reference for optimizing tobacco structure to improve the quality of cigarettes. [Method]Through principal component analysis, number of principal components and load values of each layer structure of low-(A), medi-um-(B) and high-class(C) were determined. Correlation analysis between cut tobacco structure and physical indexes for cigarette were conducted to explore the relation between cut tobacco structure and physical quality. [Result]The structure of cigarettes of three brands were different. The structure of each cigarette could be simplified into two principal components , and all the cumulative variance contribution rate were more than 80.000%, and were 80.689%(low class), 83.982%(medium class) and 84.001%(high class) respectively. These data could represent the original eight layers of tobacco layer structure ratio. The main factors affecting the physical quality of low-class cigarettes were cut tobacco at 2.80-4.75 mm and ≤2.00 mm in main component 1; those affecting the physical quality of medium- and high-class cigarettes were cut tobacco at 2.00-3.35 mm and ≤1.00 mm in main component 1. [Conclusion]Cut tobacco structure distributions in different-class cigarette are different, and the effects of cut tobacco structure on cigarette quality are different. In actual production, the enterprises can optimize cut tobacco structure in different-class cigarettes to improve the quality and stability. For low-class cigarette, the proportion of medium and long cut tobacco should be increased and that of short cut tobacco should be de-creased. In terms of medium- and high-class cigarettes, the proportion of long cut tobacco should be controlled to reduce the negative effects of long cut tobacco on overall cigarette quality.关键词
