The protein content of CCM and the pH values for CCM, CCGM and CGM significantly differed (P < 0.05) between the 1st and 28th day of storage. The pH values presented no significant differences (P > 0.05) among the different cheeses. Sheehan et al. (2009) observed a decrease in the pH values of semi-hard cheeses manufactured from a mixture of caprine and bovine milk during 150 days of cold storage
