Problems solved by technology

[0004] However, in the actual use of tree moss absolute, limited by technical issues such as raw materials for the production of tree moss absolute and the stability of the preparation process, different batches of tree moss absolute will have certain differences in the content of substances and the quality of use
On the other hand, during the storage and use of tree moss absolute oil, the chemical components in the absolute oil are susceptible to oxidation and deterioration due to the influence of light, air and other factors. At the same time, certain chemical reactions will occur between its internal molecules, such as transesterification, Esterification, phenolic condensation, aldol condensation, aldehyde condensation, formation of xylogen, etc., which in turn lead to deterioration of flavor
The existence of these influencing factors can easily lead to the instability of the use effect of tree moss absolute, which in turn leads to the instability of cigarette production quality
[0005] In order to overcome the instability of flavor and fragrance products and ensure the stability of cigarette quality, in the prior art, the quality control method for tobacco flavor and fragrance is mainly to carry out routine physical and chemical index detection, and the quality control of tree moss absolute is no exception. , mainly through the detection and comparison of physical and chemical indicators, and then evaluate the quality of absolute oil, but in-depth research and analysis can find that this evaluation method can only conduct a preliminary evaluation of the quality of flavors and fragrances from the appearance, and cannot accurately and effectively monitor the quality of flavors and fragrances. The quality of flavors fluctuates, so it is impossible to truly ensure the stability of cigarette product quality

Embodiment 1

[0063] For 5 different batches of tree moss absolute essence samples from the same manufacturer, the quality fluctuation and whether they can be practically applied were evaluated in detail by using the detection method provided in this application. The specific process is briefly introduced as follows.

[0064] (1) Construction of gas chromatogram

[0065] Using a gas chromatographic thermal conductivity detector, detect the standard sample of tree moss absolute oil, and construct the gas chromatograms of volatile and semi-volatile components in the tree moss absolute sample;

[0066] The volatile and semi-volatile components are: methylpyrazine, trimethylpyrazine, methylcyclopentenolone, benzyl alcohol, tetramethylpyrazine, guaiacol, nicotine, damascenone , α-Damascenone, phenethyl benzoate and other compounds.

[0067] (2) Construction of liquid chromatogram

[0068] Use the diode array detector of liquid chromatography to detect the standard sample of tree moss absolute ...

Embodiment 2

[0083] Generally speaking, the acid value index is related to the chemical composition of flavor products, which can reflect the change of flavor composition to a certain extent. However, since the change of acid value is a manifestation of a comprehensive change, it cannot fully and accurately reflect the change of the chemical composition of the flavor. In order to further show that the detection and evaluation method provided by this application is more accurate than the conventional acid value index in reflecting the changes in the chemical composition of the essence, the inventors measured 5 different production batches of tree moss absolute products.

[0084] The specific assay method is the same as in Example 1, and the specific assay results are shown in Table 2 below.

[0087] Analysis of the data in the above table shows that the acid valu...

Embodiment 3

[0089] In order to determine the critical point value (critical value) of the quality fluctuation of tree moss absolute, combined with the smell evaluation results, select 9 samples (deteriorated samples that appeared in warehouse storage) with obvious differences in smell evaluation results, and compare them with No. 1 standard product For comparison, the change value of the large peak and the cosine value of the angle between the small peaks of these nine samples were calculated, and the correlation between the smell evaluation results and the change value of the large peak and the cosine value of the angle between the small peaks was preliminarily studied. The specific calculation results are shown in Table 3 below.

[0091]

[0092] Smell evaluation standard: consistent (38.1-40), basically consistent (34.1-38), slightly different (30.1-34), obvious difference (below 30)....

Abstract

The invention belongs to the technical field of quality control over cigarette essence and flavors and particularly relates to a method for selecting cigarette tree moss absolute oil. The method comprises the steps that firstly, chromatographic peaks of main volatile and semi-volatile components in cigarette tree moss absolute oil essence are distinguished, then a critical point of quality fluctuation of the cigarette tree moss absolute oil essence is set according to a scent evaluation method, and the quality fluctuation situation of the tree moss absolute oil is assessed comprehensively according to a large peak change value, a small peak change value and the setting situation of the critical value. Through comprehensive analysis and research, it can be seen that compared with a conventional method of only detecting physical and chemical indexes, associativity between an evaluation method and the chemical components in the essence is higher and more sensitive, when the tree moss absolute oil quality is fluctuated, easier, rapider and more accurate judgment can be conducted through the evaluation method, thus good technical support is laid for tree moss absolute oil selection andcigarette quality stabilizing, and good practicable value is achieved.

Description

technical field [0001] The invention belongs to the technical field of quality control of flavors and fragrances for tobacco, and in particular relates to a method for selecting treemoss absolute for tobacco. Background technique [0002] During the smoking process of cigarettes, the aroma and taste of cigarette smoke mainly come from the natural aroma substances accumulated in the process of tobacco growth and development, as well as the aroma substances formed in the process of conditioning, rebaking and aging. However, because tobacco is a kind of agricultural product, and due to differences in natural climate conditions, soil and other growth environments, as well as differences in modulation techniques and modulation methods, even the same variety of tobacco leaves will taste different in actual use. There are obvious differences in sensory qualities such as , miscellaneous gas, aroma, pungency and pungency. In order to solve this technical problem, on the one hand, ad...
