Problems solved by technology

[0003] In the actual procurement process of the cigarette industry, agronomists place more emphasis on the appearance quality of tobacco leaves, while technicians use membership function and principal component analysis methods to analyze and evaluate the chemistry of cigarette raw materials, and formulators pay more attention to the sensory quality of tobacco leaves. There are many tobacco leaf quality indicators that characterize the raw material base of cigarettes. Although the information contained in these indicators can fully reflect the information of tobacco leaf quality indicators in theory, there is a strong correlation between each indicator, resulting in information redundancy. adversely affect the results of the information analysis
At present, in the process of optimizing the procurement of cigarette raw materials, either only focus on the single index of tobacco leaf quality; or study the relationship between multiple indexes, but have not made a comprehensive evaluation of the multi-index system

Embodiment 1

[0040] The samples were collected from the primary flue-cured tobacco leaf samples of four base units in the three cigarette industrial production areas of Chuxiong, Dali and Lijiang in Yunnan Province, which mainly produce flue-cured tobacco. The variety is the largest main planted variety in the township. Select 35 representative samples of C3F grade in the industrial and commercial handover samples, and the sampling volume of each sample is 3kg.

[0041] 1. Analyze the collected data

[0042] (1) Quantitative evaluation of the appearance quality of the tobacco leaves in the cigarette raw material base

[0043] Appearance quality indicators include: color, maturity, leaf structure, identity, oil content, and chroma. The quantitative evaluation method is based on the GB2635-92 flue-cured tobacco grading standard to determine the scoring standard for appearance quality (Table 1). The flue-cured tobacco leaf grading technicians judge and score the individual appearance quality...

Embodiment 2

[0097] (1) Obtain 3 samples of tobacco leaves to be evaluated from 4 base units in 3 production areas of Yunnan Chuxiong, Dali and Lijiang of Jiangsu China Tobacco Industry Co., Ltd., and determine the scoring standard for appearance quality according to the GB2635-92 flue-cured tobacco grading standard (Table 1) . Each individual appearance quality index of the sample is judged and scored item by item. Use the methods specified in YC / T159-2002, YC / T160-2002, YC / T161-2002, YC / T162-2002, YC / T173-2003 to determine the total sugar and reducing sugar, nicotine, and total nitrogen in tobacco leaf samples. , chlorine, potassium. The measured chemical composition content was converted into percentage. The sugar-base ratio refers to the ratio of the total sugar content to the nicotine content, and the potassium-chloride ratio refers to the ratio of the potassium content to the chlorine content. Refer to the standard YC / T138-1998 to establish the evaluation criteria for the sensory ...

Abstract

The invention discloses an index screening and processing method for evaluating quality of tobacco leaves. The method is characterized by comprising the following steps: determining 21 tobacco leaf quality indexes, screening the quality evaluation indexes by utilizing a main component analysis and relevant analysis way, grading the quality evaluation indexes by utilizing probability distribution, determining quality evaluation index weight by utilizing a layering analysis way, establishing a tobacco leaf quality judgment function by utilizing a K-average value clustering and multi-category gradual judgment analysis way, and detecting the accuracy of the judgment function. The tobacco leaf quality index which can accurately analyze and evaluate the tobacco leaf quality can be more systematically and comprehensively screened from the tobacco leaf quality indexes of multiple base units.

Description

technical field [0001] The invention belongs to the technical field of cigarette raw materials, and in particular relates to an index screening and processing method for evaluating the quality of tobacco leaves. Background technique [0002] Tobacco leaf is the only strategic material for the cigarette industry. Under the background of accelerated reform and adjustment of the national tobacco industry, and with new development opportunities and new development space, the supply and optimal allocation of cigarette raw materials will be the cornerstone and keystone of the long-term development strategy of cigarette brands. As a key link, high-quality cigarette raw materials with stable quality and quantity are the key to ensure the stable quality of cigarette brands and the success of brand expansion. Creating high-quality cigarette brands with high-quality cigarette raw materials can also effectively solve the problem of homogeneity of cigarette brands. With the State Tobacc...
