Patent number: 8367365Abstract: It is intended to provide a method for determining a carbohydrate which enables more accurate determination of a carbohydrate. The invention for achieving this object is directed to a method for determining a carbohydrate using a digestive enzyme, characterized in that as the digestive enzyme, an animal-derived low-molecular-weight carbohydrate digestive enzyme is used. More specifically, the invention is directed to a method for determining a carbohydrate using a digestive enzyme, characterized by comprising a first reaction step using thermostable ?-amylase; a second reaction step using protease and amyloglucosidase; and a third reaction step using an animal-derived low-molecular-weight carbohydrate digestive enzyme.Type: GrantFiled: May 6, 2008Date of Patent: February 5, 2013Assignee: Nagasaki Prefectural and Municipal Univ. Corp.Inventors: Tuneyuki Oku, Sadako Nakamura
