| 摘要 | Whey from bovine milk is treated by a process involving passing whey through a diatomaceous earth filter, subjecting the filtered whey to ultrafiltration with water injection to form a whey protein concentrate and contacting the concentrate with a strongly acidic cationic exchange resin to produce a whey protein concentrate low in viable and total microbial count, low in mineral salt and having a pH in the range of 2.7 to 3.6. | ||||||
| 权利要求 | 1. A PROCESS FOR PRODUCING A WHEY PROTEIN CONCENTRATE SUITABLE FOR INCORPORATION INTO BEVERAGES WHICH COMPRISES PROVIDING WHEY FROM BOVINE MILK, PASSING THE WHEY THROUGH A DIATOMACEOUS EARTH FILTER, SUBJECTING THE WHEY TO ULTRAFILTRATION WITH WATER INJECTION TO FORM A WHEY PROTEIN CONCENTRATE AND THEREAFTER CONTACTING THE CONCENTRATE WITH A STRONGLY ACIDIC CATIONIC EXCHANGE RESIN TO PRODUCE A WHEY PROTEIN CONCENTRATE LOW IN VIABLE AND TOTAL MICROBIAL COUNT, LOW IN MINEARL SALT AND HAVING A PH IN THE RANGE OF 2.7-3.6. 2. A process according to claim 1 which comprises heating the whey after passage through the diatomaceous earth filter and prior to ultrafiltration to a temperature of about 37*C. 3. A process according to claim 1 which comprises carrying out the ultrafiltration at pressures in the range of 100-300 psi. 4. A process according to claim 1 which comprises cooling the whey protein concentrate to about 5*C. prior to contacting the concentrate with the ion exchange resin. 5. A process according to claim 1 which comprises drying the whey protein concentrate after contacting the concentrate with the ion exchange resin. 6. A process for producing a whey protein concentrate suitable for incorporation into beverages which comprises removing at least a portion of casein and milk fat from whey from bovine milk, pasteurizing the whey at a temperature below the thermal denaturation point of the whey, cooling the whey, passing the cooled whey through a diatomaceous earth filter, subjecting the filtered whey to ultrafiltration with water injection to form a whey protein concentrate and thereafter contacting the concentrate with a strongly acidic cationic exchange resin to produce a whey protein concentrate low in viable and total microbial count, low in mineral salt and having a pH in the range of 2.7-3.6. 7. A process according to claim 6 which comprises heating the whey after passage through the diatomaceous earth filter and prior to ultrafiltration to a temperature of about 37*C. 8. A process according to claim 6 which comprises carrying out the ultrafiltration at pressures in the range of 100-300 psi. 9. A process according to claim 6 which comprises cooling the whey protein concentrate to about 5*C. prior to contacting the concentrate with the ion exchange resin. 10. A process according to claim 6 which comprises drying the whey protein concentrate after contacting the concentrate with the ion exchange resin. |
