1470325 Dextrose; starch hydrolysis CPC INTERNATIONAL Inc 1 April 1974 [10 April 1973 28 Jan 1974(3) 18 March 1974] 14441/74 Heading C2S [Also in Division C3] Granular starch is converted to starch hydrolysates containing dextrose by agitating a mixture of the granular starch, water and an alphaamylase enzyme at or above the normal initial gelatinization temperature and below the actual gelatinization temperature at pH 4-7, any residual non-soluble starch substantially retaining its granular ungelatinized form. Optionally a saccharifying enzyme, e.g. glucoamylase or beta-amylase may be included with the alphaamylase or may be used in a subsequent treatment step to give a high maltose-maltotriose syrup. The preferred alpha-amylase is derived from Bacillus Richeniformis, e.g. NCIB 8059, 8061, or ATCC 6598, 6634, 9945A or 11945.
