Effect of Certain Chemical Factors on the Melting Quality of Process Cheese

Abstract
Fat, moisture, and free tyrosine contents and pH values were not related to the melting quality of cheddar cheese, as measured by the reduction in height of a standard cheese cylinder after exposure to a temperature of 100C for 15 minutes. However, free tyrosine content increased as the cheese aged. No relationship was noted between melting quality and fat, moisture contents on pH values of process cheese, but the evidence indicated that when free tyrosine was above a given level, the melting quality was satisfactory.
