在晾烟中,人们认为TSNA是由烟叶调制期间硝酸盐经微生物还原形成的亚硝酸盐与烟草生物碱反应形成的。由此考虑可以通过利用反硝化细菌减少烟叶中的亚硝酸盐来抑制TSNA的形成,使亚硝酸盐还原为氮,以及可以利用TSNA分解细菌减少调制后烟叶中已有的TSNA。本实验利用来自烟草植株的
In air-cured tobacco, it is thought that TSNA is formed by the reaction of nitrite formed by the microbial reduction of nitrates with tobacco alkaloids during tobacco leaf modulation. It is considered that TSNA formation can be inhibited by using denitrifying bacteria to reduce nitrite in tobacco leaves, nitrite can be reduced to nitrogen, and TSNA can be used to decompose bacteria to reduce pre-existing TSNA in the prepared tobacco leaves. The experiment used from tobacco plants
