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

[0041] The evaluation method for flavoring uniformity of shredded tobacco based on PCA ellipse area of ​​the present embodiment comprises the following steps:

[0042] Step (1), prepare control samples

[0043] Take A brand shredded tobacco, and use A brand essence to flavor evenly at 3.3‰ (mass ratio). The flavored shredded tobacco was divided into 16 parts on average, and 10 g of each part was sampled, and each part was packed in a ziplock bag for testing to obtain a control sample.

[0044] Step (2), prepare the sample to be tested

[0045] Divide the finished shredded tobacco sample of brand A into 16 parts on average, take 10 g of each part, and put them in ziplock bags for testing, so as to obtain the samples to be tested.

[0046] Step (3), solid phase microextraction-gas chromatography-mass spectrometry analysis

[0047] Solid-phase microextraction-gas chromatography-mass spectrometry was performed on the control sample and the sample to be tested. Accurately weighe...

Embodiment 2

[0072] The evaluation method for flavoring uniformity of shredded tobacco based on PCA ellipse area of ​​the present embodiment comprises the following steps:

[0073] Step (1), prepare control samples

[0074] Take B brand shredded tobacco, and use B brand essence to evenly flavor at 3.5‰ (mass ratio). The flavored shredded tobacco was divided into 10 parts on average, and 10 g of samples were taken from each part, which were respectively packed in ziplock bags to be tested, so as to obtain control samples.

[0075] Step (2), prepare the sample to be tested

[0076] Divide the finished shredded tobacco sample of brand B into 10 parts on average, take 10 g of each part, and put them in ziplock bags for testing to obtain the samples to be tested.

[0077] Step (3), solid phase microextraction-gas chromatography-mass spectrometry analysis

[0078] Perform solid-phase microextraction-gas chromatography-mass spectrometry analysis on the above-mentioned control sample and the sa...

Embodiment 3

[0088] The evaluation method for flavoring uniformity of shredded tobacco based on PCA ellipse area of ​​the present embodiment comprises the following steps:

[0089] Step (1), prepare control samples

[0090] Take C brand shredded tobacco, and use C brand essence to flavor evenly at 3.1‰ (mass ratio). The flavored shredded tobacco was divided into 25 parts on average, and 10 g of each part was sampled, respectively packed in ziplock bags for testing to obtain a control sample.

[0091] Step (2), prepare the sample to be tested

[0092] Divide the finished shredded tobacco sample of brand D into 25 parts on average, take 10g of each part, put them in ziplock bags for testing, and obtain the samples to be tested.

[0093] Step (3), solid phase microextraction-gas chromatography-mass spectrometry analysis

[0094] Perform solid-phase microextraction-gas chromatography-mass spectrometry analysis on the above-mentioned control sample and the sample to be tested, specifically t...

Abstract

The invention relates to a tobacco shred perfuming uniformity evaluation method based on PCA ellipse area. The method comprises the following steps: preparing a reference sample, preparing a to-be-tested sample, performing solid-phase micro-extraction-gas chromatography-mass spectrometry, computing the PCA ellipse area and result analysis of the reference sample and the to-be-tested sample in a PCA score plot. The PCA ellipse area of the main component score plot is computed, and the size of the perfuming uniformity can be quantified through the average deviation, and then two groups of samples with uniform and non-uniform perfuming can be accurately distinguished, and the perfuming uniformity can be quantified through the average deviation, and the method has popularization and application values. By adopting solid-phase micro-extraction, the volatile and semi-volatile components in the essence an flavor and tobacco shred can be effectively measured; and a peak thereof is selected asa common mode peak to perform principle component analysis, and the result is more accurate.

Description

technical field [0001] The invention relates to a method for evaluating the flavoring uniformity of shredded tobacco, in particular to a method for evaluating the flavoring uniformity of shredded tobacco based on the PCA ellipse area. 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. 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 tobacco quality monitoring, quality evaluation, and quality consistency. [0003] Quantitative characterization of cigarette flavoring uniformity has always been a difficult problem in cigarette technology. The industry has carried out a lot of work on evaluating cigarette flavoring uniformity. Perfume was used as a marker to evaluate th...
