[0003]
However, due to the complex chemical composition of tobacco flavors and fragrances, there are many types, and the flavor components added to cigarette shreds are the same, but the content is different, and the added flavor content is also less
Using one or several characteristic compounds as markers to detect the uniformity of flavoring is not only difficult to find markers, but also difficult to add markers in large-scale production, so reasonable comprehensive test results cannot be obtained

Abstract
The invention relates to a tobacco shred perfuming uniformity detection method based on XPS, which belongs to the technical field of tobacco shred detection. The detection method comprises the following five steps of XPS analysis of the cigarette shreds which are not perfumed, XPS analysis of a perfumed sample, data processing, data calculation and perfuming uniformity judgment. The method does not need to adopt an additional characteristic marker or select a specific component as the characteristic marker for analysis, and is simple and feasible. Compared with other gas chromatography-mass spectrometry uniformity analysis methods, the detection time is only about 3-5 min and is better than 40-50 min of general gas chromatography-mass spectrometry analysis, the detection efficiency is improved by nearly 10 times, and the method is easy to apply and popularize.
Description
technical field [0001] The invention belongs to the technical field of shredded tobacco detection, and in particular relates to an XPS-based detection method for flavoring uniformity of shredded tobacco. Background technique [0002] Cigarette formula has always been regarded as the core technology of cigarette companies, but adding flavors and fragrances to cigarettes is even more regarded as a key technology. The silk making and flavoring process is an indispensable key process in the production of cigarette shreds. Its task is to accurately and evenly apply a certain amount of essence to the blended cut tobacco according to the requirements of production and formula. At present, some enterprises have made some attempts to control the uniformity of flavoring, but mainly deduce and calculate it from a theoretical point of view. There is no relevant systematic literature report in the industry on the quantitative characterization of flavoring uniformity. [0003] However, d...
