Embodiment 1

[0061] (1) Materials and instruments:

[0062] (1) Material: cigarette A of a certain brand;

[0063] Reagents: dichloromethane (AR, Shanghai Anpu Scientific Instrument Co., Ltd.); diacetyl, isovaleric acid, vanillin, ethyl palmitate, δ-octylactone, naphthalene (purity greater than 98%, all purchased from Bailingwei).

[0064] (2) Instruments: AG204 electronic balance (sensitivity: 0.0001g, Swiss METTLERTOLEDO company); blast constant temperature drying oven (101A-2, Shanghai Experimental Instrument General Factory); headspace instrument (G1888, Agilent); GC-MS / MS (SCION456GC-TQ, Bruker Company); pipette gun (Tripette Company).

[0065] (2) Preparation of samples and determination of characteristic substances:

[0066] (1) Determination of 5 characteristic substances by HS-GC-MS / MS method

[0067] A. Sample preparation: Remove the filter tip from the finished cigarette A, peel off the tipping paper, and conduct moisture determination according to "YC / T31 Tobacco and Tobac...

Embodiment 2

[0099] Repeat the process of Example 1, select another brand of cigarette B, measure its 5 kinds of characteristic substance content with HS-GC-MS / MS method, measured value is as shown in table 6, and the odor activity value of 5 kinds of characteristic substances is as shown in table 7.

[0100] Table 6 HS-GC-MS / MS method to determine the results of 5 kinds of characteristic substances (ug / g) in B brand cigarettes

[0101] serial number

[0102] Odor activity values ​​(O i )

[0103] serial number

[0104] B brand cigarette milk aroma index (N B ) = 1.89, indicating that the cigarette aroma of this brand has a slightly milky aroma style, which is slightly higher than that of brand A.

Embodiment 3

[0106] Organize 14 technicians with the national cigarette sensory evaluation qualification certificate to test the aroma style indicators of A and B brands of cigarette samples (flue-cured tobacco aroma, air-dried tobacco aroma, fresh aroma, fruity aroma, spicy aroma, woody aroma, and green aroma) , flower fragrance, herbal fragrance, etc.) to evaluate and obtain the evaluation score of the milk fragrance index. The results are shown in Table 8.

[0107] Table 8 Comparison of milk flavor index and sensory evaluation value of two brands of cigarettes A and B

[0108] brand

[0109] It can be seen from Table 8 that there is no significant difference between the milky fragrance index obtained in Examples 1-2 and the sensory evaluation score of the milky fragrance index, which proves the accuracy of the method proposed by the present invention for characterizing and evaluating the milky fragrance characteristics in cigarette fragrance. feasibility. Moreover, during t...

Abstract

The invention discloses a method for accurate characterization and evaluation of a milky aroma characteristic in a cigarette aroma. Quantitative data of aroma substances is obtained through an HS-GC-MS / MS detection method, and a cigarette milky aroma note index N is calculated and constructed through a corresponding aroma substance threshold. The method is simple to operate, difficult to interference of impurities, and accurate in detection results. The selectivity and the sensitivity of the GC-MS / MS are higher than those of GC-MS, and the problems that the GC-MS is low in sensitivity, lack of resolution rate, poor in selectivity, prone to production of false-positive results and unable to provide enough qualitative / quantitative information and the like are avoided. The cigarette milky aroma characteristic is correspondingly described and expressed from a substance base perspective, the subjectivity of sensory smoke panel tests is avoided, and the milky aroma style of cigarette products is objectively comprehensively characterized and evaluated.

Description

technical field [0001] The invention belongs to the technical field of cigarette sensory quality evaluation and analysis, and in particular relates to a method capable of accurately characterizing and evaluating the milk aroma feature in cigarette aroma. Background technique [0002] As a burning and smoking consumer product, the sensory quality of cigarettes is its core and soul, so the evaluation and analysis of cigarette sensory quality has always been one of the most important contents in cigarette technology work. The literature survey shows that in recent years, a large number of technical research and development have been carried out around the sensory quality of cigarettes, which can be summarized into two types: evaluation of cigarette sensory quality and analysis of substances related to sensory quality. [0003] 1. Evaluation of sensory quality of cigarettes [0004] There are currently two methods for evaluating the sensory quality of cigarettes, one is the com...
