Aspects of the present disclosure relate to electrochemical reduction of tobacco-specific nitrosamines (TSNAs). According to certain methods described herein, a tobacco composition containing one or more TSNAs and nicotine is contacted with a solvent to form a tobacco mixture. In some embodiments, the tobacco mixture is introduced into an electrochemical device comprising an anode and a cathode. The tobacco mixture may, in some cases, form at least part of an initial electrolyte mixture that is in physical contact with at least a portion of the anode and at least a portion of the cathode. In some instances, an electrical potential is applied between the anode and the cathode, thereby reducing one or more TSNAs in the initial electrolyte mixture and producing a reduced electrolyte mixture. In certain cases, application of the electrical potential between the anode and the cathode does not cause non-TSNA components of the tobacco mixture (e.g., nicotine) to undergo electrochemical reduction or any other chemical reaction.
本公开的各个方面涉及烟草特异性亚
硝胺(
TSNAs)的电
化学还原。根据本文所述的某些方法,将含有一种或多种
TSNA 和
尼古丁的烟草组合物与溶剂接触以形成烟草混合物。在某些实施例中,将烟草混合物引入由阳极和阴极组成的电
化学装置中。在某些情况下,烟草混合物可至少构成初始电解质混合物的一部分,该混合物与阳极的至少一部分和阴极的至少一部分发
生物理接触。在某些情况下,在阳极和阴极之间施加电势,从而减少初始电解质混合物中的一种或多种
TSNA,并产生还原电解质混合物。在某些情况下,在阳极和阴极之间施加电势不会导致烟草混合物中的非
TSNA 成分(如
尼古丁)发生电
化学还原或任何其他
化学反应。
