| Outline of Final Research Achievements |
Advanced glycation end-products (AGEs) produced in the late stages of the Maillard reaction are contained in various foods and are possible to be involved in the development of chronic diseases. In this study, we comprehensively evaluated the Maillard reaction products and attempted to elucidate the factors that influence the production of AGEs in foods. Validation using model reaction systems showed that not only the reducing ability of sugars, but also the type and binding mode of sugars are involved in the formation of specific AGEs and their precursors, α-dicarbonyl compounds (α-DCs). In addition, validation using foods led us to clarify formation mechanism of AGEs contained in baked bread.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では多種類のAGEsやα-DCsをモニターできる分析系を新たに構築し、AGEsおよび関連成分（糖質、アミノ化合物、アマドリ化合物、α-DCs）を包括的に解析することが可能となった。モデル系と実際の飲食品での検証を組み合わせることで、AGEs生成に関与する因子を新たに複数同定することができた。本研究で見出されたAGEs生成メカニズムに関する知見は、AGEs低減に向けた方策を講じるための一助となりうる。
