Abstract
A process for isolating a protein fraction from an aqueous solution or suspension containing the said fraction in admixture with other substances, which comprises subjecting the aqueous solution or suspension to ultrafiltration to obtain a retentate, diluting the retentate, subjecting the diluted retentate to at least one further ultrafiltration treatment and recovering a retentate containing the protein fraction.
Claims9
A process for isolating a protein fraction from milk containing said fraction in admixture with other substances, which comprises subjecting said milk to ultrafiltration to obtain a first retentate and a permeate, diluting said retentate with a volume of acidic aqueous liquid having a pH between 3 and 5, said volume being equal to or greater than that of said permeate, subjecting the diluted retentate to at least one further ultrafiltration treatment and recovering a second retentate containing said protein fraction.
A process for isolating a protein fraction from acidic milk containing said fraction in admixture with other substances, which comprises subjecting said acidic milk to ultrafiltration to obtain a first retentate and a permeate, diluting said retentate with a volume of acidified water having a pH of from 5 to 3, said volume being equal to or greater than that of said permeate, subjecting the diluted retentate to at least one further ultrafiltration treatment and recovering a second retentate containing said protein fraction.
