Firstly, chemical characteristics (water content, pH, Brix and total organic acid content) were analyzed. In all standard samples, there were little differences in the chemical characteristics, but total organic acid content reduced in store samples compared with standard samples. Secondly, aroma concentrate of each Kokuto was carried out by gas chromatographic analysis. In all Kokuto samples, about 30 peaks and shoulders were obtained, and the main 23 peaks were numbered. Therefore, Kokuto aroma was considered to be due to the integrated effects of a large number of volatile components. Thirdly, aroma profiles of two types of Kokuto were analyzed by gas chromatographic data and statistical method (pattern similarity analysis). In case of 22 peaks as variables, the pattern similarities of Kokuto B and Kokuto C for Kokuto A were small. Consequently, the differences of aroma profiles in two types of Kokuto could be characterized by this method.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3858"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
