| 摘要: |
| 探讨了氮素形态、变黄温度、烘烤设备等因素对烤烟烟叶中硝酸盐、亚硝酸盐和烟草特有亚硝胺（TSNA）含量的影响。结果表明，烤烟烟叶中硝酸盐、亚硝酸盐和TSNA含量基本呈现出随肥料中硝态氮比例增加而增加的趋势；低温拉长变黄处理烤后烟叶TSNA含量最高，其次为低温变黄，高温变黄最低；密集烤房对TSNA含量的影响最大，水泥预制板平板式换热器烤房影响较小。烤烟烟叶内TSNA含量与硝酸盐、亚硝酸盐含量均显著或极显著正相关，但与亚硝酸盐的关系更为密切。 |

| Effects of nitrogen form and baking on tobacco-specific nitrosmaines (TSNA) and precursor |
|
|
| Abstract: |
| The effect of nitrogen form,yellowing temperature,curing facility on the content of nitrate, nitrite and Tobacco-specific nitrosmaines (TSNA) were studied. The results showed that the nitrate,nitrite and TSNA content increased with the nitrate nitrogen content increasing in the fertilizer;while low temper ature and yellowing postponing condition resulted in the highest content of TSNA,followed by low temper ature yellowing condition and high temperature yellowing condition;the bulk curing barn had biggest effect on the TSNA content,while cement slab surface plate type barn had little effect. There were prominent relations between TSNA,nitrate and nitrite content in flue curing tobacco leaf,and the relationship between TSNA and nitrite content was much closer. |
