Embodiment 1

[0063] (1) Materials and instruments:

[0064] (1) Material: cigarette A of a certain brand;

[0065] Reagents: dichloromethane (AR, Shanghai Anpu Scientific Instrument Co., Ltd.); absolute ethanol (AR, Shanghai Reagent No. 1 Factory); benzaldehyde, β-cyclic citral, ethyl cinnamate, α-angelica lactone, γ - Undecalactone, Dihydroactinolactone, Damascenone, β-Damascenone, Geranylacetone, α-Ionone, Phenylethyl Alcohol, Phenylacetaldehyde, 5-Methylfurfural, Ethyl Malt Phenol, furanone, acetophenone, valone, farnesyl acetone, and naphthalene (purity greater than 98%, all purchased from Bailingwei).

[0066] (2) Instruments: AG204 electronic balance (sensitivity: 0.0001g, METTLER TOLEDO, Switzerland); blast constant temperature drying oven (101A-2, Shanghai Experimental Instrument General Factory); headspace instrument (G1888, Agilent); GC- MS / MS (SCION 456GC-TQ, Bruker Company); pipette gun (Tripette Company).

[0067] (2) Preparation of samples and determination of characterist...

Embodiment 2

[0102] Repeat the process of Example 1, select another brand cigarette B, measure its 18 kinds of characteristic substance contents with HS-GC-MS / MS method, measured value is as shown in table 6, and the odor activity value of 18 kinds of characteristic substances is as shown in table 7.

[0103] Table 6 The results of HS-GC-MS / MS determination of 18 characteristic substances (ug / g) in B brand cigarettes

[0109] B brand cigarette sweet aroma index (T B) = 5.95. It shows that the sweet aroma style of cigarettes of this brand is stronger, but not to a strong degree, and the sweet aroma style of cigarettes of this brand is slightly higher than that of brand A cigarettes.

Embodiment 3

[0111] Organize 14 technicians with the national cigarette sensory evaluation qualification certificate to test the aroma style indicators (flavor of flue-cured tobacco, air-dried tobacco, fragrance, fruity, spicy, woody, and green aroma) of cigarette samples of A and B brands. , flower fragrance, medicinal herb fragrance, etc.) to evaluate the sweet fragrance index evaluation score. The results are shown in Table 8.

[0112] Table 8 Comparison of sweet aroma index and sensory evaluation value of cigarettes of A and B brands

[0113] brand

[0114] As can be seen from Table 8, there is no significant difference between the sweet aroma index obtained in Examples 1-2 and the sensory evaluation score of the sweet aroma index, which proves the accuracy of the method for characterizing and evaluating the sweet aroma characteristics in cigarette aroma proposed by the present invention. feasibility. Moreover, in the process of implementation, the subjectivity of conventi...

Abstract

The invention discloses a method for exactly characterizing and evaluating sweet aroma characteristics in cigarette aroma. Aroma substance quantitative data are acquired through an HS-GC-MS/MS detecting method, and a cigarette sweet aroma note index T is obtained by calculating and establishing a threshold value of a corresponding aroma substance. The method is easy and convenient to operate, not easily disturbed by impurities, and accurate in detecting results. The selectivity and the sensitivity of GC-MS/MS are higher than those of GC-MS; the problems that the sensitivity of the GC-MS is low, the resolution is insufficient, the selectivity is low, false positive results are easily generated, and enough qualitative/quantitative information cannot be given and the like are avoided. According to the method, the sweet aroma characteristics of a cigarette are described and expressed correspondingly from the perspective of material basis; the subjectivity of sensory evaluation is avoided; the sweet aroma style of a cigarette product is characterized and evaluated objectively and comprehensively.

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 sweetness and aroma characteristics of 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 cigarette...
