However, traditional \u03b2-chitin production methods involve alkaline treatment at approximately 90 \u00b0C 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 \u03b2-chitin and water-soluble peptides using only water at temperatures of 150\u2013250 \u00b0C for 30\u2013120 min. Solid \u03b2-chitin was converted to its nanofiber form and the physicochemical properties of the \u03b2-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 \u03b2-chitin and protein.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_6_description_30": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7\uff08\u30b3\u30f3\u30c6\u30f3\u30c4\u306e\u7a2e\u985e\uff09", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_6_description_5": {"attribute_name": "\u5f15\u7528", "attribute_value_mlt": [{"subitem_description": "International Journal of Biological Macromolecules.189:921-929(2021)", "subitem_description_type": "Other"}]}, "item_6_link_3": {"attribute_name": "\u4fe1\u5dde\u5927\u5b66\u7814\u7a76\u8005\u7dcf\u89a7\u3078\u306e\u30ea\u30f3\u30af", "attribute_value_mlt": [{"subitem_link_text": "\u9577\u7530, \u5149\u6b63", "subitem_link_url": "https://soar-rd.shinshu-u.ac.jp/profile/ja.WmLUZFTp.html"}]}, "item_6_publisher_4": {"attribute_name": "\u51fa\u7248\u8005", "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_select_64": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "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_39": {"attribute_name": "NII ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0141-8130", "subitem_source_identifier_type": "PISSN"}]}, "item_6_source_id_40": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00233999", "subitem_source_identifier_type": "NCID"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "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": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2022-09-01"}], "download_preview_message": "Download / Preview is available from 2022/8/31.", "file_order": 0, "filename": "IJBM20210810.pdf", "filesize": [{"value": "1.8 MB"}], "format": "application/pdf", "future_date_message": "Download is available from 2022/8/31.", "is_thumbnail": false, "licensetype": "license_5", "mimetype": "application/pdf", "size": 1800000.0, "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "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 \u03b2-chitin nanofibers and peptides for lowering blood pressure", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Environment-friendly utilization of squid pen with water: Production of \u03b2-chitin nanofibers and peptides for lowering blood pressure", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "16", "path": ["1309/1310"], "permalink_uri": "http://hdl.handle.net/10091/0002000351", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2021-09-03"}, "publish_date": "2021-09-03", "publish_status": "0", "recid": "2000351", "relation": {}, "relation_version_is_last": true, "title": ["Environment-friendly utilization of squid pen with water: Production of \u03b2-chitin nanofibers and peptides for lowering blood pressure"], "weko_shared_id": -1}
