Abstract

The invention relates to a cigarette formula quality trend analysis method based on volatile characteristic components in cut tobacco. The method includes the following steps that 1, samples are prepared; 2, the samples are pretreated; 3, the samples are treated and detected, wherein HS-GC/MS is adopted for analysis; 4, according to the contents of non-volatile characteristic components in different batches, the principal component analysis-Mahalanobis distance is adopted to study the quality trend change of the samples, and similarity analysis of the different samples is conducted. By means of the method, the contents of the volatile characteristic components in the cigarette cut tobacco can be directly acquired, principal components in the components are obtained, score vectors of the principal components are used for two-dimensional or three-dimensional spectrum recognition, the spectrum is displayed through a computer and chemometrics method, and classification of the different samples is achieved. The cigarette product formula quality monitoring method is stable and objective; no contamination is generated; on the premise of guaranteeing detection accuracy and sensitivity, detection cost is lowered, and detection time is shortened.

Description

technical field [0001] The invention relates to a cigarette formula quality trend analysis method, in particular to a cigarette formula quality trend analysis method based on volatile characteristic components in shredded tobacco, and belongs to the technical field of cigarette formula quality control. Background technique [0002] Cigarettes are an extremely complex chemical multi-component system. The quality of smoking and the formation of style characteristics are the result of the synergy between the internal chemical components of cigarettes (including added flavors and fragrances). To judge the changes in the quality of cigarette product formulations, the existing conventional chemical indicators and data processing methods are often difficult to achieve a comprehensive system analysis and obtain satisfactory results due to the single indicators and insufficient information. At present, cigarette quality evaluation mainly uses near-infrared spectroscopy combined with ...
