Preparation of Cigarette Spices with Caramel Flavor Using Pineapple Concentrates as Sugar Sources

Abstract:

The study aimed to use Amadori compounds with fruit concentrates as sugar sources for cigarette flavoring. Under the reaction conditions for the synthesis of Amadori compounds，pineapple concentrates reacted with different amino acids to form pineapple and caramel-like flavors. Products were added into cigarettes and the sensory evaluation found that the perfume，Fru-Pro，produced by pineapple concentrate with proline，was the best. Then under the glucose-proline model system the synthesis of Fru-Pro was conducted and monitored by HPLC and its pyrolysis products were analyzed by GC/MS. Results showed that the formation of Fru-Pro corresponded approximately to the consumption of glucose during 0~2 h，the synthesis rate gradually decreased but was always higher than the decomposition rate during 8~24 h，and after 24 h，the decomposition became faster than the synthesis. For the whole process，glucose was the limiting reactant. The main pyrolysis products included pyrroles，pyridines，pyrans，furans，cyclopentenone and pyrazines and many of them were caramel-like compounds.
