| Outline of Final Research Achievements |
To prevent food poisoning caused by histamine which has been on the increase, it is very important that histamine accumulation should be arrested at the stage of distribution and storage because histamine is not detoxified by cooking for its stability against heat. In this study, we searched for constituents in some edible plants that inhibit the activity of histamine producing enzyme, histidine decarboxylase, derived from adherent germ to food and production of histamine in fish. Six ellagitannins in meadowsweet, petal of rose red or cloves were identified as strong inhibitors of the enzyme. It is likely that a short-time immersion of fish in the hot-water extracts of these plants protects accumulation of histamine based on ellagitannin content of the extracts.
