Embodiment 3

[0105] 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, medicinal herb fragrance, etc.) to evaluate, and obtain the green fragrance index evaluation score. The results are shown in Table 8.

Abstract

The invention discloses a method for accurately characterizing and evaluating green fragrance characteristics of a cigarette fragrance. Through a HS-GC-MS / MS detection method, fragrant substance quantification data is obtained and through a corresponding fragrant substance threshold, a cigarette green fragrance index Q is calculated and constructed. The method can be operated simply, is not interfered by impurities and has accurate detection results. GC-MS / MS selectivity and sensitivity are higher than those of GC-MS so that the problem that the GC-MS has low sensitivity, a poor resolution ratio and poor selectivity, can easily produce false positive results and cannot provide enough qualitative / quantitative information is solved. From a substance base perspective, the method provides corresponding description and expression of cigarette green fragrant characteristics, prevents sensorial rating subjectivity and realizes objective and comprehensive characterization and evaluation of a green fragrance style of a cigarette product.

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 characteristics of green flavor 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, o...
