Chemical Composition of the Laboratory–Made Mozzarella Cheese
Figure (1) shows the result of titrable acidity as lactic acid (mg/100g) during storage period for mozzarella cheese types prepared from cow’s, goat’s and mixture milk (1:1 cow’s milk: goat’s milk). The titrable acidity (expressed as lactic acid%) of cow’s milk mozzarella cheese (CMMC) was 0.203 ± 0.01%, this value was lower than that of El Owni and Osman[7], who reported a value of 0.59 ± 0.90% in CMMC. The titrable acidity of goat’s milk mozzarella cheese (GMMC) was 0.13 ± 0.01% which was lower than the value 1.51 ± 0.02% obtained by Srbinovska et. al.[8]. However, the titrable acidity of GMMC was significantly lower than that of CMMC and MMMC throughout the storage period; however no significant difference was found in titrable acidity of mixture milk mozzarella cheese at 30 day at storage period compared to other samples.
