Here, we performed 1H and 13C solid-state NMR measurements on Indonesian green beans, roasted beans, and spent coffee grounds (SCGs). In the NMR spectra, there were liquid-like TAG containing linoleic acids based on observed signals of -CH=CH-CH2-CH=CH- group in an acyl chain, which play a role in decreasing TAG’s melting point. We found TAG was still abundant in the SCGs from NMR spectra. After lipids were removed from SCGs, the intensity of the TAG signal decreased considerably, with approximately 64% of the TAG was successfully extracted. We described the chemical structure of TAG in coffee beans and demonstrated that it is possible quantify the amount of extracted TAG using solid-state NMR.\nTriacylglycerol as a source of biodiesel fuel in spent coffee grounds, green and roasted coffee beans was thoroughly characterized by 1H and 13C solid-state NMR spectroscopy.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1080/09168451.2019.1571899","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10824164","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168451","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Chemistry, Chemical Engineering, and Life Science, College of Engineering Science, Yokohama National University"},{"subitem_text_value":"Instrumental Analysis Center, Yokohama National University"},{"subitem_text_value":"Department of Chemistry, Chemical Engineering, and Life Science, College of Engineering Science, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kanai, Noriko"}],"nameIdentifiers":[{"nameIdentifier":"35585","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshihara, Naoki"}],"nameIdentifiers":[{"nameIdentifier":"35596","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawamura, Izuru"}],"nameIdentifiers":[{"nameIdentifier":"34923","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20452047","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20452047"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"20190103_BBB_IK.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20190103_BBB_IK.pdf","url":"https://ynu.repo.nii.ac.jp/record/9848/files/20190103_BBB_IK.pdf"},"version_id":"c20b75cc-2f36-4295-a475-1b2b6ebfcc9e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Coffee","subitem_subject_scheme":"Other"},{"subitem_subject":"triacylglycerol","subitem_subject_scheme":"Other"},{"subitem_subject":"linoleic acid","subitem_subject_scheme":"Other"},{"subitem_subject":"polysaccharide","subitem_subject_scheme":"Other"},{"subitem_subject":"biodiesel","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Solid-state NMR characterization of triacylglycerol and polysaccharides in coffee beans","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Solid-state NMR characterization of triacylglycerol and polysaccharides in coffee beans"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-05-29"},"publish_date":"2019-05-29","publish_status":"0","recid":"9848","relation_version_is_last":true,"title":["Solid-state NMR characterization of triacylglycerol and polysaccharides in coffee beans"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:06:09.229514+00:00"}
