Method for accurately identifying flue-cured tobacco flavor types

Abstract

The invention discloses a method for accurately identifying flue-cured tobacco flavor types. According to the invention, a smoking and evaluating group is organized, wherein the members in the group are good at sensing the scents of flue-cured tobaccos; 8 characteristic scent components are evaluated and quantified with a blind-review method, wherein the 8 scents are tobacco scent, fragrant scent, sweet scent, fruit scent, flower scent, spicy scent, wood scent, and coke scent; scent score data is adopted as a basis, and a flavor style characteristic profile diagram is drawn; with the profile diagram as a basis, flue-cured tobacco scent area index S is obtained with a calculation formula S=1 / 2*sinC*a*b, wherein a and b are two adjacent flavor style characteristic values, and C is an included angle of a and b. If S is smaller than 25.0, the flue-cured tobacco is strong-flavored flue-cured tobacco. If S is 26.0-30.0, the flue-cured tobacco is middle-flavored flue-cured tobacco. If S is greater than 30.0, the flue-cured tobacco is light-flavored flue-cured tobacco. The flue-cured tobacco flavor type identifying method provided by the invention is practicable, accurate, convenient, and visual.

Description

technical field [0001] The invention belongs to the technical field of cigarette determination, in particular to a method for accurately identifying the flavor type of flue-cured tobacco. Background technique [0002] The flavor type of flue-cured tobacco is an important basis for the quality evaluation of tobacco leaves and the application of cigarette formula. As early as the 1960s, Zhu Zunquan, Wang Chenghan, etc. divided Chinese tobacco leaves into three flavor types: light-flavored, middle-flavored, and strong-flavored. However, there is still no systematic evaluation method for how to evaluate these three flavor types of flue-cured tobacco leaf raw materials. Based on this, the evaluation of flue-cured tobacco flavor is listed as one of the key research contents in the "three vertical and three horizontal" projects of the national bureau's major special project of characteristic high-quality tobacco leaf development. In recent years, on the basis of sensory quality ev...

Problems solved by technology

In recent years, on the basis of sensory quality evaluation and analysis of its characteristic components, people have constructed the discriminant function of flue-cured tobacco flavor type. The discriminant functions of flue-cured tobacco flavor types are also different, and the identification results of flue-cured tobacco flavor types are also different. In addition, these methods are time-consuming and expensive to analyze and detect the characteristic components of flue-cured tobacco aroma style.
