Abstract：Three dipeptide Amadori intermediates (APs)were prepared by three representative dipeptide Gly-Gln,Ala-Gln and Gly-Gly as the nitrogen source,and glucose as sugar sources.The reaction process was monitored by HPLC to compare reactivity of dipeptides,the reactivity order is Ala-Gln>Gly-Gln>Gly-Gly. The purity and fracture modes of three dipeptide APs were characterized and analysis using LC-MS/MS and ESI-MS/MS.The results showed that the LC/MS purity of three dipeptide APs was up to 95% (Gly-Gln-APs),97% (Ala-Gln-APs)and 98% (Gly-Gly-APs).Three fracture pattern of dipeptide APs was similar, the main fragment ions including loss of sugar molecules formed [M-1 62]+and [M-1 80]+fragment ions;and loss of water molecule is formed [M-36]+and [M-84]+ions.The cigarette application evaluation showed that the three dipeptide APs have encountered with incense smoke harmonize and improve the aroma and the amount of gas concentration,wherein Ala-Gln-APs shows the best effects.An obvious positive effect could be found both in aroma and taste characteristics.
