卷烟降焦减害技术研究进展

Study development in techniques for reducing cigarette tar and harmful materials

通过选育富钾烟草品种,改进调制工艺,采用现代化生物技术和生物材料,既能保持烟草传统本色,又可降低卷烟燃烧过程中产生的烟碱、烟焦油、一氧化碳、氢氰酸、氨及稠环芳烃等有害物质,减轻因吸烟对人体健康的影响。

Developing the tobacco varieties through selecting potassium rich varieties, improving mix technology,applying physical, chemical and biological techniques and biological materials not only can keep the traditional natures of the tobacco plant, but also can reduce the contents of the harmful components such as nicotine, tar, carbon monoxide, hydro cyanicacid, ammonia and PAH （polycyclic aromatic hydrocarbons）, which are produced during smoking, thus lessen the harm to smokers.
