However, traditional β-chitin production methods involve alkaline treatment at approximately 90 °C for its separation from the protein, thus not suitable as a functional peptide, as it is mixed with an alkaline aqueous solution. This study examined the conversion of squid pen into solid β-chitin and water-soluble peptides using only water at temperatures of 150–250 °C for 30–120 min. Solid β-chitin was converted to its nanofiber form and the physicochemical properties of the β-chitin nanofibers were almost the same as those produced by the traditional method. Because this method uses only water, the protein in the squid pen may also be a functional peptide for lowering blood pressure, by inhibiting the Angiotensin-1 converting enzyme. High-temperature water treatment is a promising environment-friendly technique for complete utilization of squid pen components, including β-chitin and protein.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"International Journal of Biological Macromolecules.189:921-929(2021)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"長田, 光正","subitem_link_url":"https://soar-rd.shinshu-u.ac.jp/profile/ja.WmLUZFTp.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V."}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.ijbiomac.2021.08.190","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0141-8130","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00233999","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Osada, Mitsumasa","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Nishiwaki, Mizuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Watanabe, Takashi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-09-01"}],"filename":"IJBM20210810.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_5","mimetype":"application/pdf","url":{"url":"https://soar-ir.repo.nii.ac.jp/record/2000351/files/IJBM20210810.pdf"},"version_id":"2d557acb-efb1-4fca-bbb9-2f75d869d582"}]},"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":"Environment-friendly utilization of squid pen with water: Production of β-chitin nanofibers and peptides for lowering blood pressure","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Environment-friendly utilization of squid pen with water: Production of β-chitin nanofibers and peptides for lowering blood pressure","subitem_title_language":"en"}]},"item_type_id":"6","owner":"16","path":["1310"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-09-03"},"publish_date":"2021-09-03","publish_status":"0","recid":"2000351","relation_version_is_last":true,"title":["Environment-friendly utilization of squid pen with water: Production of β-chitin nanofibers and peptides for lowering blood pressure"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2022-12-14T03:50:55.124757+00:00"}
