Abstract
PURPOSE:To efficiently produce glucose, by continuously carrying out starch hydrolytic reaction of liquefaction and saccharification using an immobilized alpha-amylase and glucoamylase. CONSTITUTION:Water is added to starch, such as potato, corn or wheat, to form a slurry at pH4.5-6.5 with 30-50% solid content. The resultant slurry is then reacted with a soluble alpha-amylase, partially liquefied and subjected to hydrolytic reaction with an immobilized alpha-amylase to measure the viscosity of the formed dextrin. The liquefying reaction condition is controlled on the basis of the measured values thereof and the resultant dextrin solution is regulated so as to provide a DE within the range of 10-20, preferably 15-18. The obtained dextrin solution is subsequently brought into contact with an immobilized glucoamylase by a method for a packed bed or contact with hollow membranes, etc., to provide glucose.
