Problems solved by technology

[0004] Since tobacco flavors and fragrances are blended with a variety of spices and appropriate solvents, and most of the spices are made from natural materials, the quality of the product may fluctuate due to the influence of various factors such as the place of origin and processing.
At present, the quality of flavors and fragrances for tobacco is mainly evaluated by measuring their physical and chemical indicators (such as acid value, relative density, refractive index, etc.) according to "Flavors for Tobacco" (YC/T 164-2012), which cannot objectively and accurately reflect the quality of the liquid. Intrinsic chemical quality and quality fluctuations
With the continuous de

Embodiment 1

[0028] Example 1 Flavoring essence sample for tobacco

[0029] In accordance with the provisions of Part 10 "Sampling of Tobacco Flavors and Fragrances" in the tobacco industry standard YC / T145.10-2003, samples of flavored flavors were sampled, and five types of samples were taken in total, with a total of 186 batches (13 randomly selected Fragrance flavor samples as verification samples).

[0030] Take 1g of the flavoring essence sample for tobacco and dilute it to 10mL with absolute ethanol, pass through a 0.4μm filter membrane, and perform GC / MS analysis to obtain the chromatographic fingerprint of the flavoring essence sample for tobacco (see figure 1 ).

[0031] Perform data processing on the fingerprints of the known types of tobacco flavors and fragrances, including baseline drift, noise processing, peak drift correction, peak resolution, analysis, etc., so that the fingerprint data collection meets the modeling requirements. The collected fingerprints were analyzed f...

Embodiment 2

[0037] Embodiment 2 flavoring essence sample for tobacco

[0038] According to the provisions of Part 10 "Sampling of Tobacco Flavors and Fragrances" in the tobacco industry standard YC / T145.10-2003, samples of flavoring flavorings were sampled, and two types of samples were taken in total, with a total of 72 batches (10 flavorings were randomly selected) Flavor samples as verification samples).

[0039] Accurately weigh 0.500 g of flavoring flavor sample for tobacco into a thermal desorption tube (4 mmi.d. × 178 mmL) for TDS-GC / MS analysis. Obtain the chromatographic fingerprint of cigarette flavoring essence sample (see Figure 5).

[0040] Perform data processing on the fingerprints of the known types of tobacco flavors and fragrances, including baseline drift, noise processing, peak drift correction, peak resolution, analysis, etc., so that the fingerprint data collection meets the modeling requirements. The collected fingerprints were analyzed for components.

Abstract

The invention discloses a tobacco flavor and perfume quality analysis method. The tobacco flavor and perfume quality analysis method comprises the following steps: 1) preparing a sample; 2) acquiring a fingerprint spectrum; 3) building a model; 4) verifying the model; 5) analyzing the quality. The tobacco flavor and perfume quality analysis method can comprehensively detect the interior quality of the tobacco flavor and perfume, and combines with a chemometric method to reflect the interior chemical quality and the quality fluctuation situation of the flavor and perfume.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a method for analyzing the quality of flavors and fragrances for tobacco. Background technique [0002] Fingerprints have now become a technical tool for studying complex material systems as a whole. Generally speaking, the construction of fingerprints is mainly divided into three categories: chromatographic fingerprints, spectral fingerprints, and deoxyribonucleic acid (DNA) fingerprints. . Due to the characteristics of fingerprint feature analysis, spectrum overall analysis, and macroscopic inference analysis, fingerprints are suitable for analyzing the stability of complex chemical substances. Therefore, it is widely used in the quality evaluation of traditional Chinese medicine and even natural products, especially in the quality control of traditional Chinese medicine, Applied research on authenticity identification and other aspects has continued to deepen, and relevant res...
