PROCESS FOR THE RECOVERY OF PROTEINS
The starting aq. soln. or suspension contains 5-30% of dry non-fat materials, e.g. milk, and fat content not >5%. Ultrafiltration is performed at 5-30 degrees C and 1-20 atm. The residue is diluted with water, acidified water (pH 5-3) or saline soln. (about the same vol. as the ultrafiltrate). Wh...

Zusammenfassung: | The starting aq. soln. or suspension contains 5-30% of dry non-fat materials, e.g. milk, and fat content not >5%. Ultrafiltration is performed at 5-30 degrees C and 1-20 atm. The residue is diluted with water, acidified water (pH 5-3) or saline soln. (about the same vol. as the ultrafiltrate). Whey may be used as diluent to increase proteins. Dilution controls the chemical compsn. of the product. The process can be operated continuously and can produce any desired ratio of protein/lactose, casein/lactalbumin, Ca/Na, Ca/casein, e.g. for cheese. |
