Method for analysis of tobacco leaf quality change trend in lamina controlled atmosphere storage process

Abstract

The invention discloses a method for analysis of tobacco leaf quality change trend in a lamina controlled atmosphere storage process. The method is characterized by including the steps of: S01, preparation of analysis samples; S02, comprehensive evaluation of each index Ci value; and S03, data analysis by SPSS with the calculated index Ci value's data. The method for analysis of the tobacco leaf quality change trend in a lamina controlled atmosphere storage process provided by the invention mainly utilizes the index Ci value and SPSS to scientifically analyze and explore the difference significance between different warehousing modes and the change trend thereof at different time points. The method can objectively and accurately analyze the difference significance at different time points and between different treatments, defines the impact effect comparison of different treatments and the change trend along with time, and has the advantages of simplicity, high efficiency and scientificity, etc., and can be used as a statistical analysis method in accordance with the repeated measurement design data in the scientific research field of tobacco.

Description

technical field [0001] The invention relates to a method for analyzing the quality change trend of tobacco leaves in the controlled atmosphere storage process of flake tobacco, and belongs to the technical field of tobacco analysis. Background technique [0002] In recent years, as the tobacco industry pays more and more attention to storage and maintenance, a large number of researches on tobacco alcoholization technology have been carried out. Since the natural alcoholization of tobacco leaves is a gentle and slow fermentation method, in order to fully and deeply understand the influence of test conditions on the alcoholization effect of tobacco leaves, it is necessary to follow up and evaluate the quality of the same test sample during the alcoholization cycle; The samples are independent, but the data measured by the same test sample at different time points are often not independent, and there is a correlation; this is in contradiction with the independence conditions r...

Since the natural alcoholization of tobacco leaves is a gentle and slow fermentation method, in order to fully and deeply understand the influence of test conditions on the alcoholization effect of tobacco leaves, it is necessary to follow up and evaluate the quality of the same test sample during the alcoholization cycle; The samples are independent, but the data measured by the same test sample at different time points are often not independent, and there is a correlation; this is in contradiction with the independence conditions required by traditional statistics, and it is not suitable to use t-test, variance analysis, random The analysis and processing of block design and other methods make the statistical analysis of data of this type of storage test somewhat complicated. Therefore, the verification of the experimental results in the past is mostly visually judged by descriptive statistical methods.
