| Abstract: |
| The waste tobacco leaves produced after topping in the field was used to obtain the extract，and the
extract flavor was improved by Maillard reaction and the special tobacco flavor was prepared. Using sensory evaluation
as the evaluation index，the reaction temperature，pH and heating time were optimized by single factor and orthogonal
methods. The optimal conditions for preparation of special tobacco flavor were as following reaction temperature
120℃，pH 12，heating time 180 min. Through GC/MS analysis，29 kinds of compounds were identified，including
four pyrazines，six alcohols，three lipids，two aldehydes，two ketones，two alkenes，one amine. Aroma substances
such as megastigmatrienone，benzyl alcohol，dihydroactinidiolide，aromadendrene and other components，were the
key aroma substances. |
