Problems solved by technology

However, due to the complex chemical composition of tobacco flavors and fragrances, there are many types, and the flavor components added to cigarette shreds are the same, but the content is different, and the added flavor content is also less
Using one or several characteristic compounds as markers to evaluate the uniformity of flavoring is not only difficult to find markers, but also difficult to add markers in large-scale production, so it is impossible to obtain reasonable comprehensive evaluation results

Embodiment 1

[0037] This embodiment aims at using two flavoring methods, vertical barrel and drum barrel, in the aromatization process of the existing workshop, and the flavors and fragrances of the two flavoring methods are the same as the raw shredded tobacco.

[0038] The method for analyzing the uniformity of the shredded tobacco flavoring method based on the PCA average distance of the present embodiment includes the following steps:

[0039] Step (1), performing SPME-GC-MS (solid phase microextraction-gas chromatography-mass spectrometry) analysis on the flavored shredded tobacco obtained by different flavoring methods.

[0040] Flavored shredded tobacco samples obtained by flavoring methods of vertical barrel and drum barrel were randomly selected, and samples were taken 7 times respectively, with a sample volume of 20 g each time. Accurately weigh 0.7g of each sample (approximately the mass of cut tobacco of a conventional cigarette) and place it in a 20mL brown headspace bottle, a...

Abstract

The invention relates to a method for analyzing the uniformity of tobacco shred perfuming modes based on a PCA average distance. The method comprises the steps of carrying out SPME-GC-MS analysis on perfumed tobacco shreds obtained in different perfuming modes; carrying out SPME-GC-MS analysis on online raw material tobacco shreds; determining characteristic markers; calculating the PCA average distance of the different perfuming modes in a PCA score graph; and evaluating the uniformity of the different perfuming modes. The solid-phase micro-extraction is adopted, so that volatile and semi-volatile components in flavors and fragrances and the tobacco shreds can be effectively measured; and by removing the common components of the flavors and fragrances and the tobacco shreds, the specificcomponents in the flavors and fragrances are selected as the characteristic markers, and the peaks are selected as common mode peaks to carry out the PCA, so that a result is more accurate.

Description

technical field [0001] The invention relates to a method for analyzing the uniformity of the flavoring manner of shredded tobacco, in particular to a method for analyzing the uniformity of the flavoring manner of shredded tobacco based on the PCA average distance. Background technique [0002] Cigarette formula has always been regarded as the core technology of cigarette companies, but adding flavors and fragrances to cigarettes is even more regarded as a key technology. Fingerprint technology has been widely used in the fields of judging and analyzing the quality of traditional Chinese medicine and traceability of agricultural and sideline products. Because chemical fingerprints have the characteristics of fingerprint feature analysis and macroscopic inference analysis. In recent years, research on the application of fingerprints in the field of tobacco has made rapid progress, and there are more and more reports in this area. At present, there are many applications in tob...
