Samples of Binchuan burley tobacco, Dazhou sun-cured tobacco and Baofeng flue-cured tobacco were collected to investigate changes in TSNAs contents during storage and their response to different temperature treatment. Results showed that both total and individual TSNAs contents in both burley and sun-cured tobacco increased with increase of storage time. The most significant increase occurred in high temperature months, for example, from middle of April until August, especially for NNN in burley tobacco. Both total and individual TSNAs contents in flue-cured tobacco which had less nitrate contents were very low and showed non-significant changes after 45°C treatment. While both total and individual TSNAs contents in burley tobacco and sun-cured tobacco were much higher and increased rapidly after the treatment of 45°C, with nitrate decreasing slightly and nitrite rising significantly.
