The main goal of this research is to develop prediction models that can estimate anthocyanin pigment content in purple-fleshed sweetpotato 'AYAMURASAKI' and 'MURASAKIMASARI' using spectrophotometry in the visible range (450-600nm). Using stepwise multiple linear regression, calibration model wavelengths were selected using the second derivative of the smoothed absorbance spectral data. The five-wavelengths model had a correlation coefficient R of 0.861 with a standard error of calibration (SEC) of 0.048 and prediction (SEP) of 0.041 for the 'AYAMURASAKI' sample sets, and an R of 0.756 with a SEC of 0.019 and a SEP of 0.019for the 'MURASAKIMASARI' sample sets.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学農学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty of Agriculture, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00236503","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05446066","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"永田, 雅輝","creatorNameLang":"ja"},{"creatorName":"ナガタ, マサテル","creatorNameLang":"ja-Kana"},{"creatorName":"Nagata, Masateru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小林, 太一","creatorNameLang":"ja"},{"creatorName":"コバヤシ, タイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Kobayashi, Taichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"KJ00004782365.pdf","filesize":[{"value":"498.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004782365.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/3447/files/KJ00004782365.pdf"},"version_id":"e3f7c63a-6363-4c5d-a154-696536949d18"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"アントシアニン色素, 吸光度, スペクトル解析, 品質評価, 紫イモ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Absorbance, Anthocyanin pigment content, Purple-fleshed sweetpotato (Ipomoea batatas Poir), Quality estimation, Spectrum analysis","subitem_subject_language":"en"}]},"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":"スペクトロフォトメーターを用いた紫イモのアントシアニン色素評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スペクトロフォトメーターを用いた紫イモのアントシアニン色素評価","subitem_title_language":"ja"},{"subitem_title":"Study on anthocyanin pigments estimation for purple-fleshed sweetpotato using spectrophotometer","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["74","46","349","356"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-01-21"},"publish_date":"2008-01-21","publish_status":"0","recid":"3447","relation_version_is_last":true,"title":["スペクトロフォトメーターを用いた紫イモのアントシアニン色素評価"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-07-30T03:21:44.946419+00:00"}
