Abstract

The invention belongs to the technical field of tobacco, and particularly relates to a method for measuring release quantity of ammonia in tobacco leaves, which is characterized in that: a thermal cracking - ion chromatography is adopted. Since the tobacco leaves are free from being made into cigarettes to measure the ammonia content in the smoke of the cigarette, the method is simple to operate, the labor and the physical resource can be saved, and the cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of tobacco, in particular to a method for measuring ammonia release in tobacco leaves. Background technique [0002] Ammonia is recognized as a major harmful component in mainstream cigarette smoke. Ammonia in cigarette smoke comes from nitrogen-containing compounds in tobacco and other auxiliary materials, including proteins, amino acids, nitrates, ammonium salts, amides, alkaloids, and Nitrogen heterocyclic compounds, the appropriate content of nitrogen-containing compounds can maintain the appropriate physiological strength and concentration of smoke, but too high content of nitrogen-containing compounds will not only make the smoke rough and produce burnt smell, but also produce a large number of harmful components. During the smoking process of cigarettes, these nitrogen-containing compounds will produce ammonia to varying degrees. Ammonia not only affects the taste of cigarettes, but also stimulates th...
