Abstract:

To study the influence of cigarette blend on ammonia of mainstream smoke, the ammonia in mainstream smoke of cigarettes which prepared with different cigarette blend was detected by ion chromatography. The ammonia in mainstream smoke was significant affected by tobacco of different areas, the content of cut stem, reconstituted tobacco and expanded tobacco. The experimental results showed that the content of ammonia in internal tobacco was lower than that in foreign tobacco, and the content of ammonia released in upper part of tobacco leaf was the higher than that in middle part and lower part. And it is also found a negative correlation between the ammonia and the content of 3 kinds of tobacco motioned above. The ammonia of cigarette mainstream smoke could be decrease by increasing the mount of the internal tobacco, the middle part and lower part of tobacco, cut stem, reconstituted tobacco and expanded tobacco.
