Problems solved by technology
[0009] The above-mentioned patent documents all use one or a few chemical components as markers to characterize the uniformity of the flavoring and feeding process, which cannot fully reflect the entire complex composition of the flavor liquid, and thus bring certain problems to the determination of uniformity. defect
In addition, because the cigarette sample matrix is very complex, and the selectivity of HPLC, GC and GC / MS is poor, the target compound is easily interfered by impurities, resulting in insufficient resolution and unstable baseline, thus affecting accurate quantification

Abstract
The present invention provides an evaluation method for the uniformity of flavoring of cigarettes. The evaluation method used adopts GC-MSQQQ. Firstly, each category of essence is analyzed, and the common aroma components of each category are determined, and the common aroma components are used as cigarette flavoring components A marker for the evaluation of the uniformity of aromatization; then use the MRM mode to quantitatively analyze the common aroma components in a series of standard working solutions, and draw a linear working curve with the peak area of each aroma component versus the concentration; use the MRM mode to quantitatively analyze the aroma components The content of each common aroma-causing component in each sample of the aroma process, and calculate the standard deviation of the addition amount of each common aroma-causing component in the aromatization sample SD i and coefficient of variation cv i ; SD i value and cv i The smaller the value, the better the uniformity. The evaluation method of the present application can accurately and effectively analyze the uniformity of flavoring in shredded tobacco of cigarettes.
Description
technical field [0001] The invention relates to a method for evaluating cigarettes, in particular to an evaluation method for flavoring uniformity of cigarettes. Background technique [0002] In recent years, various modern instrumental analysis methods such as high performance liquid chromatography (HPLC), gas chromatography (GC) and mass spectrometry (GC / MS) have become commonly used methods in the evaluation of cigarette flavoring uniformity. With the advantages of high separation efficiency, fast analysis speed and good stability, it is an effective method for evaluating the uniformity of cigarette flavoring. [0003] The application number is 201210164865.2, which involves a method for evaluating the uniformity of feeding in Burley tobacco based on marker detection. It is through the analysis of the chemical components of the tobacco leaves before and after feeding Burley tobacco, and determines that glycyrrhizic acid is the chemical component that characterizes the un...
