Embodiment 1

[0021] Inject natural flavors and fragrances for cigarettes into cigarettes through a cigarette injection machine, put them in a constant temperature and humidity box to balance for 48 hours, and organize at least 5 smoking experts to evaluate the flavor according to the requirements of the sensory evaluation table for the flavor evaluation of single flavor raw materials. 174 natural flavors and fragrances were evaluated and smoked, and the functional characteristics of the selected 85 natural flavors and fragrances for tobacco in cigarettes were determined, mainly divided into flavor-enhancing function, thorn-reducing function, moisturizing function and impurity-removing function Four categories.

[0022]

[0023] At the same time, the functional characteristics of tobacco flavors and fragrances in cigarettes are divided into three categories: strong, medium and weak.

[0024]

[0025] The results are as follows:

[0026]

Embodiment 2

[0028] Volatile component detection and component classification: using the American WATERS company QuattroII gas chromatography spectrometer, DB-5ms capillary column (30m × 0.25mm × 0.25μm) to analyze 85 natural flavors and fragrances for tobacco; the inlet temperature is 250 ℃; injection volume is 1 μl; split injection, split ratio 20:1; transfer line temperature 250 ℃; solvent delay time 4min; ion source temperature 180 ℃; electron voltage 70eV. The search results were determined according to the matching degree of the NIST spectral library of the National Institute of Standards and Technology of the United States ≥ 900, and the total ion current area normalization method was used for quantification.

[0029] Classify and merge according to sugars, esters, aldehydes and ketones, terpenes, heterocycles, alkaloids, alkanols and others.

Embodiment 3

[0031] Variable setting: According to the classification data of the volatile components of the sample, combined with the division results of functional effects and quality strength, statistical analysis of the regression coefficient is performed on the correlation between the volatile components and functional effects. According to the strength value as the Y dependent variable and the chemical composition content as the X variable, the statistical analysis of the regression coefficient is carried out. The variable settings are shown in the following table:

Abstract

The invention relates to a determination method of correlation between functions of natural essence and flavor used in cigarettes and volatile components and belongs to the technical field of tobacco chemical industry and applications. In the determination method provided by the invention, the classification of volatile chemical components and the statistical analysis of regression coefficients are introduced. The method comprises the steps of: positioning of functional properties of the natural essence and flavor used in the cigarettes, detection of the volatile components and component classification, and research on the correlation between the functions and the components. Instruments and equipment used in the determination method are all purchased from the market, and the determination method has the beneficial effects that through the combination of the smoking positioning with the detection and the classification of the volatile components, a regression curve is built through a regress function of an MATLAB (Matrix Laboratory), and the functional properties of the unknown natural essence and flavor used in the cigarettes are determined through mathematical calculation so as to open up a new application field for the tobacco chemistry and application technologies, and provide a new method and train of thought for the chemical research of aa cigarette mass spectrometry.

Description

Technical field: [0001] The invention relates to a method for judging the correlation between functions and volatile components of natural flavors and fragrances for tobacco, belonging to the technical field of tobacco chemical industry and application. Background technique: [0002] Tobacco flavor and fragrance is a kind of tobacco product additive specially used for flavoring and correcting various tobacco products, so that they can produce good smoke effect when burning and smoking. Tobacco flavors and fragrances are indispensable raw materials for cigarette production, and their formula is also one of the core technologies of tobacco industry enterprises. The application of flavors, fragrances and additives is closely related to the establishment and development of cigarette brands. Natural flavors are aroma-inducing substances extracted from the flowers, fruits, leaves, stems, roots, skins or animal secretions of various natural plants. The selection of natural flavors...
