Embodiment 3

[0109] 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. , floral fragrance, medicinal herb fragrance, etc.) to obtain the evaluation score of the floral fragrance index. The results are shown in Table 8.

[0111] brand

[0112] It can be seen from Table 8 that there is no significant difference between the floral aroma index obtained in Examples 1-2 and the sensory evaluation score of the floral aroma index, which proves the accuracy and feasibility of the method proposed by the present invention for characterizing and evaluating the floral aroma characteristics in cigarette aroma. Moreover, in the implementation process, the subject...

Abstract

The invention discloses a method for exactly characterizing and evaluating flower aroma characteristics in cigarette aroma. Aroma substance quantitative data are acquired through an HS-GC-MS / MS detecting method, and a cigarette flower aroma note index H 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 flower aroma characteristics of a cigarette are described and expressed correspondingly from the perspective of material basis; the subjectivity of sensory evaluation is avoided; the flower 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 floral 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 lot of technical research and development has 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 comprehensi...
