METHOD FOR PRODUCTION OF MOLASSES OF STARCH Russian patent published in 2011 - IPC C13K1/06 C08B30/00 

FIELD: food industry.

SUBSTANCE: method for production of molasses of starch includes starch suspension preparation (accompanied by stirring), heating, starch suspension dilution, cavitation treatment envisaging suspension heating, starch suspension dilution under an enzyme preparation impact, diluted starch chilling to saccharification temperature, liquid product treatment with a saccarificating enzyme preparation in a gas vortex bioreactor (accompanied by stirring) by way of vortex motion of aerating air generated over the starch suspension surface, pressure differential between the air vortex centre and periphery equal to 1000-2200 Pa, and the produced product decontamination and boiling out. Starch suspension preparation, heating and dilution (accompanied by stirring) proceed in a cavitation apparatus ensuring a cavitation impact on the product being treated and supply of energy thereto equal to minimum 9.0±0.5 kJ/mole which is required for starch granules erosion. Starch suspension is treated in the cavitation apparatus during 2-4 hours. The enzyme preparation diluting starch suspension may be represented by alfa-amilase or amilosubtilin in an amount of 1.0-1.5 g per 1 kg of starch, the activity rating being 1500 EA in 1 g of the enzyme. The enzyme preparation saccarinating starch suspension may be represented by glucoamilase or r-amilase in an amount of 0.7-1.0 g per 1 kg of starch, the activity rating being 5000 EA in 1 g of the enzyme. The product saccharification may be performed within 25-30 hours.

EFFECT: reduction of the cycle of molasses production of starch due to a higher degree of starch granules degasation in the cavitator, a better contact of enzymes with starch and a more intensive enzymatic starch hydrolysis.
