Abstract
This invention concerns a process for preparing soluble rice protein concentrate with reduced levels of manganese, aluminum, selenium and phytic acid and improved digestibility from rice raw material comprising: PA1 digesting the raw material reduced in particle size to permit efficient enzyme action in an aqueous medium with an alpha-amylase enzyme at an operable pH and temperature for a period of time sufficient to solubilize a substantial portion of the rice starch and form a liquid slurry; PA1 heating the rice starch slurry at 105.degree. C. to 130.degree. C. for 30 to 60 seconds; PA1 separating the high protein rice flour from the rice syrup; PA1 treating a slurry of the high protein rice flour with a protease enzyme at an operable pH and temperature in an amount and for a period of time to solubilize the rice protein: PA1 clarifying the protease treated slurry to provide a soluble rice protein concentrate with reduced manganese, aluminum, selenium and phytic acid and improved digestibility. The soluble rice protein concentrate contains more the 16% protein on a solids basis, and has on a per gram protein basis, a manganese content of 50 microgram or less, an aluminum content …
