Abstract:

In order to understand and analyze the differences in Amadori compounds in different tobacco, different types of tobacco (flue-cured tobacco, oriental tobacco, burley tobacco) and different flavor types of tobacco leaves were selected, and the content of 22 Amadori compounds and their parent compounds were determined using liquid chromatography tandem mass spectrometry, liquid chromatography evaporative light scattering and amino acid automatic analyzer. The results showed that the content of Amadori compounds in different tobacco varied greatly and was closely related to the content of their parent compounds. The total amount of Amadori compounds in tobacco is about 2.42% of the dry weight, about 1.70% in oriental tobacco, and about 0.136% in burley tobacco. The total amount of Amadori compounds in the fresh flavor type tobacco is about 1.25 times that of the intermediate flavor type and about 1.5 times that of the strong flavor type. The total amount of Amadori compounds in tobacco stems is about 1.5 times that of the corresponding tobacco leaves. This study provides data support for the detection of Amadori compound and Maillard reaction research in different types of tobacco and different flavor types of tobacco leaves.

Key words: Maillard reaction, Amadori compounds, flue-cured tobacco, burley tobacco, oriental tobacco
