Evaluation method of cigarette mainstream smoke ingredient sensing style index

Abstract

The invention discloses an evaluation method of a cigarette mainstream smoke ingredient sensing style index. The method comprises the following steps of collecting cigarette samples used for building an evaluation model for smoking evaluation; building a smoking evaluation vector Yt; dissolving the mainstream smoke particle phase materials captured after the smoking of each cigarette sample; performing extraction and detection; performing spectral peak integration on a sample spectrogram; building a smoke ingredient matrix Xs; then, performing standard treatment on Xs and Yt; then, performing fitting to determine the factor number; obtaining a regression coefficient vector; building a smoke gas ingredient matrix Xt; then, performing standardization processing on Xt and Yt; next, building an evaluation model M; next, after the integration on the selected compound and internal standard peaks, building a smoke ingredient matrix Xp of the sample to be evaluated; inputting the Xp into the evaluation model M to obtain an evaluation result. The method has the advantages that the influence of subjective factors can be eliminated; the individual differences of the smoking evaluation personnel are balanced; the effect of objectively evaluating the cigarette sensing characteristics can be achieved; the work intensity of the smoking evaluation personnel is reduced; the training cost of the smoking evaluation personnel is reduced; the positive practical significance is realized on the product design, processing process design and quality supervision.

Description

technical field [0001] The invention relates to the fields of information technology and automation technology, in particular to a method for evaluating components of cigarette smoke. Background technique [0002] The chemical composition of smoke is the material basis of the sensory indicators of cigarettes. The sensory quality of cigarettes mainly depends on the interaction between many components in the smoke, and its style quality mainly depends on the contribution of the taste components in the smoke to the comprehensive experience. At present, the sensory evaluation of cigarettes mainly relies on manual smoking evaluation. Due to the influence of factors such as the physical condition of the smokers themselves, the external environment, psychological orientation, and individual differences of the smokers, the evaluation results of cigarettes have certain uncertainties, which leads to repeated smoking. lack of reliability and reliability. Therefore, it is urgent to est...
