  • Method and apparatus for analyzing starch and related carbohydrates
    Patent number: 5248597
    Abstract: A method and apparatus for the determination of the average molecular weight, average chain length or dextrose equivalent of starch and related carbohydrates containing glucose units. The starch is analyzed by determining the free glucose amount (Gf) contained in starch or related carbohydrate sample, determining a gross glucose amount (Gt) rendered by hydrolysis of starch or related carbohydrates, and further determining a glucose amount (Gr) rendered by hydrolysis of a reduced product which is obtained by reduction of reducing terminals contained in starch or related carbohydrate.The average molecular weight, average chain length or dextrose equivalent of the starch is determined using the formulas stated below from the measured amounts of the free glucose amount (Gf), and the glucose amount (Gr).
