The ORAC assayed showed that ergothioneine maintained high antioxidative activity at 25, 40, 60, 80, and 100℃. Proportional decreases in the antioxidative activity of L-ascorbic acid and garlic acid were observed with increases in temperature. L-ascorbic acid, in particular, showed a large reduction in ORAC value, with the antioxidative activity at 100℃ only 23% that at 25℃. Ergothioneine and garlic acid showed high antioxidative activity for 7 days under acidic or neutral conditions (pH 3.0, pH 5.0, and pH 7.0). Furthermore, ergothioneine maintained its antioxidative activity for 7 days under neutral and alkali conditions (pH 7.2 and pH 9.0), whereas that of garlic acid decreased to about 70% at day 3. The antioxidative activity of L-ascorbic acid decreased at every pH as time increased. From these results, it appears that ergothioneine is an excellent antioxidant on which heat and pH have little effect. Further, we found that ergothioneine has the highest level of antioxidative activity of the four amino acids tested (ergothioneine, glutathione, L-methionine and L-cysteine).","subitem_description_type":"Other"}]},"item_3_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"8","subitem_description_type":"Other"}]},"item_3_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00007823826","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11520347","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"藤女子大学人間生活学部食物栄養学科 "},{"subitem_text_value":" 藤女子大学人間生活学部食物栄養学科 "},{"subitem_text_value":" 株式会社スリービー "},{"subitem_text_value":" 札幌医科大学医療人育成センター教養教育研究部門化学教室 "},{"subitem_text_value":" 藤女子大学人間生活学部食物栄養学科藤女子大学大学院人間生活学研究科食物栄養学専攻"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"福田, 絵里"}],"nameIdentifiers":[{"nameIdentifier":"632","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"青柳 幸恵"}],"nameIdentifiers":[{"nameIdentifier":"633","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山岸 和敏"}],"nameIdentifiers":[{"nameIdentifier":"634","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"賀佐 伸省"}],"nameIdentifiers":[{"nameIdentifier":"635","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"知地 英征"}],"nameIdentifiers":[{"nameIdentifier":"636","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"FUKUDA, Eri","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"637","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"AOYANAGI Yukie","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YAMAGISHI Kazutoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"639","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"GASA Shinsei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"CHIJI Hideyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-22"}],"displaytype":"detail","filename":"KJ00007823826.pdf","filesize":[{"value":"396.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00007823826.pdf","url":"https://fujijoshi.repo.nii.ac.jp/record/417/files/KJ00007823826.pdf"},"version_id":"7a64ad52-1bc7-4645-a13c-c29249ea5115"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"タモギタケから単離したエルゴチオネインの加熱および各pHにおける抗酸化性への影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"タモギタケから単離したエルゴチオネインの加熱および各pHにおける抗酸化性への影響"},{"subitem_title":"The effects of heat and pH on the antioxidative activity of ergothioneine from Pleurotus cornucopiae.","subitem_title_language":"en"}]},"item_type_id":"3","owner":"3","path":["35"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-08-22"},"publish_date":"2016-08-22","publish_status":"0","recid":"417","relation_version_is_last":true,"title":["タモギタケから単離したエルゴチオネインの加熱および各pHにおける抗酸化性への影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T14:09:03.533276+00:00"}
