Problems solved by technology

[0004] The purpose of the present invention is to overcome the defect that the existing traditional sensory evaluation and smoking method in the style discrimination of flue-cured tobacco is greatly affected by personal subjective factors and experience; at the same time, it focuses on overcoming the time-consuming and cumbersome operation process of the existing physical and chemical analysis method, which requires a large number of instruments Equipment, many testing items, high testing costs, and difficult to popularize and apply in actual production

Embodiment 1

[0032] In this embodiment, taking C3F tobacco leaves from Xuchang, Henan Province as an example, the aroma type is judged, and the specific judgment process is as follows.

[0033] The identification method of Luzhou-flavor flue-cured tobacco based on the activity threshold value, the specific determination steps are as follows.

[0034] (1) Determination of the content of representative aroma-causing substances in smoke, specifically:

[0035] Firstly, the Henan Xuchang C3F tobacco leaf was rolled into a single cigarette, and then smoked on a smoking machine under the national standard conditions; during the smoking process, the particulate matter in the mainstream smoke was collected; in order to ensure that the particulate matter The collection effect of 20 single-material cigarettes is collected by a filter; after the cigarettes are smoked, take out the Cambridge filter in the trap, wipe it clean with absorbent cotton, and put it into a 500mL conical flask together. Put 3...

Embodiment 2

[0056] In this embodiment, taking C3F tobacco leaves from Xuchang, Henan Province as an example, the aroma type is judged, and the operation of the specific judgment process is the same as that in Embodiment 1. Only a brief explanation of the relevant judgment results is given below.

[0057] After analyzing the aroma components in the particulate matter, refer to the existing literature, and also use the threshold value ≤ 1.0×10 -3 As a screening standard, finally determine that there are 66 kinds of representative aroma components (the same types as in Example 1), and use the internal standard method to measure the content of 66 representative aroma components in the smoke; The activity thresholds of sexual aroma components were calculated separately.

[0058] Finally, according to the aroma characteristics, the 66 representative aroma components are classified into clear (green) aroma, fruity aroma, sweet aroma, nutty aroma, caramel aroma, floral aroma, milky aroma, herbal...

Embodiment 3

[0063] In this embodiment, taking B3F tobacco leaf from Chenzhou, Hunan Province as an example, its flavor type is judged, and the operation of the specific judgment process is the same as that in Embodiment 1. Only a brief explanation of the relevant judgment results is given below.

[0064] After analyzing the aroma components in the particulate matter, refer to the existing literature, and also use the threshold value ≤ 1.0×10 -3 As a screening standard, finally determine that there are 66 kinds of representative aroma components (the same types as in Example 1), and use the internal standard method to measure the content of 66 representative aroma components in the smoke; The activity thresholds of sexual aroma components were calculated separately.

[0065] Finally, according to the aroma characteristics, the 66 representative aroma components are classified into clear (green) aroma, fruity aroma, sweet aroma, nutty aroma, caramel aroma, floral aroma, milky aroma, herbal...

Abstract

The invention belongs to the technical field of flue-cured tobaccos and particularly relates to a method for identifying strong-flavor flue-cured tobaccos based on activity threshold values. The method comprises the steps of smoking of tobacco leaf, capturing of grain-phase substance, qualitative and quantitative analysis of aroma substances, calculation and addition of the activity threshold values, result judgment and the like. According to the method, flue-cured tobaccos from Henan province and Hunan province are taken as a carrier so as to research and screen the flavor type of different aroma substances and the threshold value conditions of the aroma components, and finally, the size of addition data of the threshold values of the aroma substances with the same flavor is taken as a measurement index, so as to make the main flavor of an exhaust gas system clear and determine the flavor type. Therefore, the method for identifying the strong-flavor flue-cured tobaccos based on the activity threshold values is established on the basis. Compared with the prior art, the method has the advantages that the method is simple, convenient and rapid, the judgment result is objective and reliable, and experiences and references are provided for the judgment on the different flavor types and types of tobaccos of the flue-cured tobaccos.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco, and in particular relates to an identification method for Luzhou-flavor flue-cured tobacco based on an activity threshold. Background technique [0002] Flue-cured tobacco has a long history of planting and cultivation in my country and has a wide range of planting. It is one of the important economic crops in my country. Due to the different ecological factors such as climate and soil, the aroma types of flue-cured tobacco in my country are relatively rich, which are generally divided into strong aroma type, middle aroma type and light aroma type. Due to the differences in the ecological conditions of each smoking area, there are obvious differences in the flavor and style characteristics of tobacco leaves. The flavor type of flue-cured tobacco is an important basis for the procurement of cigarette raw materials and the design of cigarette formula. In order to highlight different sty...
