Chemometrics and sensory omics analysis method for finished cigarette paper

Abstract

The invention discloses a stoichiometric and sensory omics analysis method for finished cigarette paper, which comprises the following steps: detecting finished cigarette paper samples of the same brand processed in different places to obtain GC-IMS data of the finished cigarette paper samples of the same brand produced by different cigarette factories; carrying out feature analysis and mode identification of sensory omics data on GC-IMS data of finished cigarette paper samples of the same brand produced by different cigarette factories by adopting an unsupervised and supervised mode identification method; and according to a mode identification result, evaluating the consistency of products at different production points of the multi-point processing variety. According to the stoichiometric and sensory omics analysis method for the finished cigarette paper, finished cigarette paper samples which are processed in different places and have the same brand are distinguished, abnormal samples with sensory aroma-producing component quality fluctuation are identified, and key symbolic series compounds influencing volatile compound composition and aroma-producing characteristics are screened out; and accurate evaluation of the overall quality of the product can be realized.

Description

technical field [0001] The invention relates to the technical field of tobacco product quality evaluation, in particular to a chemometrics and sensoryomics analysis method for finished cigarette paper. Background technique [0002] The flavor and fragrance system refers to the special cigarette paper prepared by adding flavors, fragrances, extracts and their materials for flavoring, sweetening, coloring and other purposes during the manufacturing process of cigarette paper. When the cigarette is burned, the flavoring additive on the cigarette paper releases flavor components through volatilization, cracking, etc. to achieve the purpose of imparting a certain characteristic flavor. In recent years, cigarette paper flavoring technology has been widely used in the production of high-end cigarettes to improve the smoking quality of cigarettes. . Due to the many volatile components, complex components and low content of aroma components in the flavor and fragrance system, the r...

Problems solved by technology

Due to the large number of volatile components, complex components, and low content of aroma components in the flavor and fragrance system, it is difficult to trace the raw materials of the flavor and fragrance system, and there is a lack of effective stability monitoring methods. The establishment of its mature and reliable quality control system has an impact on the stability of the sensory quality of cigarette brands

[0003] At present, the main methods for the quality control of flavors and fragrances in my country are still physical evaluation indicators such as acidity, miscibility, refractive index, and density. In addition, the existing GC / MS methods of foreign standards have the disadvantages of specificity and insufficient sensitivity for the detection of trace aroma compounds. , and mainly focus on the qualitative and quantitative analysis methods of targeted compounds, lack of overall quality evaluation methods for the complex system of flavor and fragrance system

The above problems constitute the shortcoming of the current quality control of flavors and fragrances
