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 Yunnan Yuxi C3F tobacco leaf as an example, its flavor type is judged, and the specific judgment process is as follows.

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

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

[0035] Firstly, the Yunnan Yuxi C3F tobacco leaves were rolled into single tobacco, and then smoked in a smoking machine under national standard conditions; during the smoking process, the particulate matter in the mainstream smoke was collected; in order to ensure the particle phase Collection effect, the particulate matter of 20 single 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 them together into a 500mL conical flask, each Put 3 filters in the Erlenmeye...

Embodiment 2

[0054] In this embodiment, Fujian Longyan C2F tobacco leaf is taken as an example to judge its flavor type, 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.

[0055] 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.

[0056] 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 aroma, creamy ...

Embodiment 3

[0061] In this embodiment, taking Yunnan Dali B3F tobacco leaf as an example, its 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.

[0062] 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.

[0063] 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 aroma, creamy arom...

Abstract

The invention belongs to the technical field of flue-cured tobacco, and in particular relates to an identification method for light-flavor flue-cured tobacco based on an activity threshold. The method includes the steps of smoking tobacco leaves, trapping particulate matter, qualitative and quantitative analysis of aroma components, calculating and summing activity thresholds, and judging results. The present invention uses the flue-cured tobacco in Yunnan and Fujian as the carrier, researches and screens the aroma types of different aroma substances in the smoke system and the threshold value of different aroma components, and finally selects the aroma substances belonging to the same aroma The sum of the data size of the activity threshold of the active threshold is used as a measurement index, so as to clarify the main fragrance of the smoke system and determine the fragrance type. Based on this, a method for identification of Fen-flavor flue-cured tobacco based on activity threshold was established. Compared with the prior art, the present invention has the advantages of simple and fast judging method, objective and reliable judging result, and also provides reference and reference for judging other flavor types of flue-cured tobacco and different flavor types of other types of tobacco.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco, and in particular relates to an identification method for light-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 styl...
