and step S1, carrying out a stability acceleration test on the finished product flavored cigarette paper sample under a preset environmental factor to obtain a stability acceleration test sample of the finished product cigarette paper.
Specifically, a plurality of finished product flavored cigarette paper samples are taken and placed in a drug stability test box, and a stability acceleration experiment is carried out under the environment with preset temperature and humidity. In one embodiment of the invention, 30 parts of the aromatized cigarette paper sample is placed in a drug stability test box, and a stability accelerated test is carried out in an environment with relative humidity of 60 ℃/85% RH.

And S2, detecting the stability accelerated test samples of the finished cigarette paper at different accelerated test times to obtain gas chromatography serial ion mobility spectrometry (GC-IMS) data of the stability accelerated test samples of the finished cigarette paper at each time point.
In an embodiment of the method for analyzing the decay characteristic of the accelerated test sample on the stability of the finished cigarette paper, the step S2 may specifically include:
and step S21, sampling the finished product aromatized cigarette paper sample placed in the drug stability test box for 1 time at preset time intervals (for example, 24h), taking 3 samples as parallel samples for testing each time, and continuously sampling for 8-10 times (for example, 10 times).
And S22, detecting the finished product cigarette paper sample after each sampling by adopting a GC-IMS flavor analyzer, and repeatedly carrying out sample injection measurement on each sample for 3 times to obtain gas chromatography series ion mobility spectrometry data of the stability acceleration experiment sample of the finished product cigarette paper at each time point.
In one embodiment, 10 batches of accelerated stability test samples are analyzed by a gas chromatography-tandem ion mobility spectrometry (GC-IMS) method, and the sample introduction of each sample is repeated for 3 times, so that 90 groups of data are counted. The obtained GC-IMS data superposition map of the stability acceleration experiment sample of the finished cigarette paper with different acceleration experiment time is shown in figure 2.
Illustratively, the assay may be performed using a german g.a.s.flavourpec GC-IMS flavour analyzer. The manufacturer and the model of the GC-IMS flavor analyzer are not particularly limited.
The GC-IMS combines the advantages of high separation degree of gas chromatography and high sensitivity of ion mobility spectrometry, can quickly detect trace volatile organic compounds in a sample without any special sample pretreatment, and is used for measuring volatile headspace components in a solid or liquid sample.
Further, headspace sampling conditions when a GC-IMS flavor analyzer is used for detection include:
the sample injection volume is 200 ul; the incubation time is 20 min; the incubation temperature is 90 ℃; the temperature of the sample injection needle is 95 ℃; the hatching rotating speed is 500 rpm;
the chromatographic conditions when the GC-IMS flavor analyzer is adopted for detection comprise that:
the chromatographic conditions of gas-ion mobility spectrometry are as follows: the analysis time is 20 min; the chromatographic column type is WAX; the column length is 30 m; the inner diameter is ID-0.53 mm; film thickness ofFT 1 μm; the column temperature is 60 ℃; carrier/drift gas of N2(ii) a The IMS temperature is 45 ℃;
GC chromatographic conditions: the drift gas flow rate is 150mL/min when the sample introduction time is 0, the carrier gas flow rate is 2mL/min, and the collection state is rec; the drift gas flow rate is 150mL/min and the carrier gas flow rate is 10mL/min when the sample introduction time is 2 min; the drift gas flow rate is 150mL/min when the sample introduction time is 20min, and the carrier gas flow rate is 100 mL/min; the drift gas flow rate is 150mL/min when the sample introduction time is 30min, the carrier gas flow rate is 100mL/min, and the collection state is stop.
Before the detection is carried out by using the GC-IMS flavor analyzer, the method further comprises the following steps:
the method for pretreating the sample specifically comprises the following steps:
0.5g of cigarette paper is put into a 20mL headspace bottle, incubated at 90 ℃ for 20min and injected.
And S3, establishing a chemometrics quantitative regression model of the GC-IMS sensory quality of the volatile compounds based on the gas chromatography tandem ion mobility spectrometry data of stability accelerated test samples of the finished cigarette paper with different accelerated test times.
Specifically, in the present invention, a chemometric quantitative regression model of GC-IMS sensory quality of volatile compounds was established by a linear regression model method in model lab Matman general chemometric solution software (Chemmind Technologies, Beijing, China). Wherein the linear regression model method comprises a partial least squares regression (PLS-R) modeling algorithm.
In a specific implementation, the measurement data obtained in step S2 may be imported into chemometrics analysis software for attenuation trend prediction modeling analysis.
Wherein the number of latent variables retained by the partial least squares regression (PLS-R) modeling algorithm is 7; performing cross validation by adopting LOO (leave-one-out) method in cross validation; the preprocessing algorithm used is logarithmic conversion.
Figure 3 is a plot of a PLSR linear regression fit obtained using GC-IMS data modelling of training set samples on finished cigarette paper acceleration test samples; fig. 4 is a cross validation result obtained by sequentially substituting cross validation set samples into a training set model and modeling the GC-IMS data of the acceleration test sample of the finished cigarette paper by PLSR analysis regression, in general, the determination coefficient of the latter is smaller than that of the former, the difference between the two reflects the overfitting degree of the model, and the closer the two are, the better the prediction performance of the model is. The results in fig. 3 and 4 show that the partial least squares regression (R2 ═ 0.9985) model algorithm is better able to predict the quantitative regression at time points for samples at different sampling time points for accelerated tests, suggesting that there is a gradual loss (decay) in volatile compounds composition over time between samples at each time point, as evidenced by the cross-validation of the model (R2 ═ 0.9955). In addition, a significant decrease in total peak area of the sample profile can also be observed along with the line graph of the acceleration experiment time point.
In the invention, when the partial least squares regression modeling algorithm is adopted for modeling, when the data preprocessing method of the model adopts logarithmic transformation, the decision coefficient and the linear relation of the model reach the best, namely the elimination (volatilization) rate of the volatile components is in direct proportion to the first power of the current concentration of the volatile components in the cigarette paper.
And step S4, analyzing the sensory stability of the aromatizing components of the finished aromatizing cigarette paper under the influence factors of the preset environment according to the chemometrics quantitative regression model.
Specifically, GC-IMS data of the sample to be detected at different accelerated test time are subjected to logarithmic transformation and then are input into a chemometrics quantitative regression model, and the attenuation tendency of the aroma compounds of the finished cigarette product at different accelerated test time is obtained.
