Glucoamylase liberated a reducing sugar from raw sweet potato starch to some extent, though the material was hardly hydrolyzed by α-amylase. At high temperature, however, the enzyme liquefied the starch. The raw starch was digested completely by glucoamylase after liquefication with α-amylase at 80℃ for 10 min. The optimum pH and temperature of glucoamylase reaction were 4.5-5.0 and 40℃, respectively. Pectinase was found to solubilize raw sweet potato at 40℃, facilitating the hydrolysis with glucoamylase. Maximum hydrolysis of raw sweet potato was obtained with glucoamylase digestion after solubilization with pectinase followed by liquefication with α-amylase at 80℃ for 10 min.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"琉球大学農学部","subitem_publisher_language":"ja"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4022"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0370-4246","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00250548","subitem_source_identifier_type":"NCID"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"琉球大学農学部学術報告","subitem_source_title_language":"ja"},{"subitem_source_title":"The Science Bulletin of the Faculty of Agriculture.
