Abstract

1,274,506. Hydrolysis of starch. GRAIN PROCESSING CORP. 13 Oct., 1969, No. 50241/69. Heading C3U. A starch hydrolyzate is produced by a process comprising treating in a first step an aqueous slurry of starch with an acid or enzyme to liquefy the starch and to provide an aqueous dispersion substantially free of residual starch granules with a measurable D.E. value not substantially above 3, then subsequently, in a second step, treating the dispersion with a dextrinizing enzyme at a temperature of 65-85‹ C., to achieve a product having a measurable D.E. value not substantially above 18, stopping the dextrinization reaction and recovering the hydrolyzate. The product may have a saccharide composition wherein the amount of glucose is less than 1% by weight and the amount of maltose is less than 6% by weight and may produce a solution free of opacity (transmittance of light rays through the hydrolyzate maintained at 10‹ C. for 48 hours is at least 70%) when solids concentration is 80% by weight for a product having a D.E. of 18.
