Problems solved by technology

[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 a scanning electron microscope energy spectrum, which belongs to the technical field of tobacco shred perfuminguniformity detection. The method comprises the steps of SEM / EDS analysis of cigarette shreds which are not perfumed, SEM / EDS analysis of cigarette shred samples after perfuming, data processing, datacalculation and the like. The detection 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 of the method is only about 10-15 min and is superior to 40-50 min of general gas chromatography-mass spectrometry analysis, the detection efficiency is improved by nearly 4 times, and the method is easy to apply and popularize.

Description

technical field [0001] The invention belongs to the technical field of detection of flavoring uniformity of shredded tobacco, and in particular relates to a detection method of flavoring uniformity of shredded tobacco based on scanning electron microscope energy spectrum. 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 quanti...
