ABSTRACT
The effects of 1) ripening 2, 7, and 14 d at 7[degrees]C before freezing; 2) tempering 7, and 14 d at 7[degrees]C after freezing; and 3) frozen storage for 1 and 4 wk at -20[degrees]C, on the meltability, stretchability, and microstructure of pasta filata and nonpasta filata Mozzarella cheeses were investigated. Cheeses were cut into 5 x 10 x 7-cm blocks and vacuum-sealed 1 d after manufacture. The results were compared to the corresponding results obtained with unfrozen control samples, aged at 7[degrees]C between 2 and 21 d. The changes in physical properties of frozen-stored pasta filata and nonpasta filata Mozzarella cheeses were consistent with critical damage to the cheese ...
