| Outline of Final Research Achievements |
In order to enhance the antioxidant function of fermented foods traditionally manufactured in various regions, this study applied the Maillard reaction, which has been widely used in food manufacturing processes. The Maillard reaction was promoted by incubating salt-fermented shrimp paste with several kinds of reducing sugars at 60°C, and the antioxidant activity was markedly enhanced as the reaction progressed. During the Maillard reaction, harmful oxidative deterioration of unsaturated fatty acids such as EPA and DHA was not observed. In addition, the amount of free amino acids significantly increased probably depending on self-digestion of amino compounds, and thus also suggested that the umami taste would be improved in the fermented food.

| Academic Significance and Societal Importance of the Research Achievements |
タウリンや EPA、DHAなど特有な機能性成分が豊富に含まれている水産発酵食は、我が国でも最近注目されているが、その抗酸化機能性の強化に関する研究例はほとんどなかった。このような状況で、本研究では各種還元糖を適当な条件で発酵食とインキュベートすることによってメイラード反応が促進され、抗酸化機能が著しく強化されることが実証され、併せて自己消化の進行にともない発酵食品の風味改善も期待された。
