The homogenates of toxic oysters were directly, or after adjusting pH, packed into retorting pouches, and heated in an autoclave or in a boiling water bath. Mouse bioassay and high performance liquid chromatographic analysis of the homogenates before and after heating demonstrated that autoclaving could reduce toxicity more rapidly than boiling, and that the reduction occurred more effectively when pH was adjusted to 7.5 with NaOH. However, in case of pH 3.0, toxicity score was slightly decreased, or increased. This phenomenon would be mainly due to conversion of C1,2 with low toxicity into GTX2,3 with high toxicity. When autoclaved adjusting the pH to 7.2 with 3 types of chemicals instead of NaOH, the homogenates of toxic oysters were also detoxified very effectively. Sodium bicarbonate (NaHCO3) was the most effective among them, requiring the shortest heating time of 5 min to reduce toxicity to less than 4 MU/g. In case of the other chemicals (sodium and ammonium phosphate buffers), however, a small amount of decarbamoyl toxins remained even after 15 min of heating. The authentic specimens of C1,2 and GTX2,3 were added to non-toxic oyster homogenates, and autoclaved similarly. The results showed that all of these components were decomposed more effectively when pH-adjusting chemicals, especially NaHCO3 was used. Without the chemicals, or with ammonium phosphate buffer, C1,2 seemed to be converted not via GTX2,3 but directly into dcGTX2,3.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告 v.82 p.99-103 , 2001","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"98259","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamagichi, Yasunaga"}]},{"nameIdentifiers":[{"nameIdentifier":"98260","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Momosaki, Youichi"}]},{"nameIdentifiers":[{"nameIdentifier":"98261","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takatani, Tomohiro"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学水産学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178473","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05471427","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"P00099-P00103"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山口, 泰永"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"百崎, 洋一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高谷, 智裕"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荒川, 修"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野口, 玉雄"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-24"}],"displaytype":"detail","filename":"82-099.pdf","filesize":[{"value":"115.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"82-099.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/23242/files/82-099.pdf"},"version_id":"d7f4fbe5-5b21-46b5-9de9-69016b0ce8f8"}]},"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":"PSP で毒化したマガキのレトルト加工による減毒","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PSP で毒化したマガキのレトルト加工による減毒"}]},"item_type_id":"3","owner":"2","path":["1632"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-02-20"},"publish_date":"2007-02-20","publish_status":"0","recid":"23242","relation_version_is_last":true,"title":["PSP で毒化したマガキのレトルト加工による減毒"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T00:55:00.266613+00:00"}
