Abstract
Abstract CONVERTING ACID WHEY TO A USEFUL PRODUCT BY HEAT DENATURING UNNEUTRALIZED ACID WHEY, SEPARATELY HEAT DENATURING THE SCRUM PROTEINS OF A LIQUID MILK PRODUCT CONTAINING SWEET SKIM MILK AND SEPARATELY ATOMIZING THE WHEY AND THE MILK PRODUCT SIMULTANEOUSLY THROUGH SEPERATE NOZZLES IN A SINGLE DRYER. THE ACID WHEY SOLIDS DO NOT SUBSTANTIALLY EXCEED ABOUT 43% BY WEIGHT OF THE COMBINED ACID WHEY AND SKIM MILK SOLIDS. THE PROCESS IS CHARACTERIZED BY THE AVOIDANCE OF NEUTRALIZING THE ACID WHEY PRIOR TO TREATMENT THUS MAKING THE DRIED PRODUCT SUITABLE FOR HUMAN CONSUMPTION.
