METHOD OF OBTAINING SUGAR-CONTAINING PRODUCT FROM CORN GRAIN Russian patent published in 2009 - IPC C13K1/06 C12P19/14 

FIELD: chemistry.

SUBSTANCE: present invention pertains to the food industry. The method involves mixing ground corn grains with water to 17-18% moisture, extrusion of the mass at 120-140°C temperature and 9-10 MPa pressure, mixing the obtained extrudate with acid water at pH 4.0-5.5 and ratio of 1:6. The extrudate is pastered and thinned at 50-70°C for 40-90 minutes by adding the xylanase enzyme preparation Shearzyme 500L in quantity of 30-60 units of xylanase activity per 1 g of extrudate. The thinned mass is centrifuged for separation from the solid residue of solution, containing protein, cooled at pH 6.5-7.0 and separated from the solution. The solution is mixed with solid residue, separated in the centrifuging process. Enzyme preparation Thermamil 120L is added to the mixture for dextrinisation, in quantity of 0.06-0.16 units per 1 g of starch at 80-95°C for 1.5-2.5 hours. The mass is then cooled to 55-65°C and saccharified with enzyme preparation glucozyme "Л400С" in quantity of 4-6 units per 1 g of starch at pH 4.3-4.6 for 2.5-3.0 hours. The obtained hydrolysate is filtered and boiled out to 70-75% content of dry substance.

EFFECT: design of an effective method obtaining sugar-containing product from corn.
