The freezing of cheeses has been used to extend its shelf-life and to expand its commercialization to distant places. The soft cheeses represent the sector with the highest dynamism and technological innovation. In the case of Mozzarella cheese, its freezing by immersion in NaCl solutions may be an innovative procedure for the dairy industry to reduce the effect of freezing on the final cheese quality, and to reduce the processing time because it combines conveniently salting and freezing processes. The main objective of this thesis was to evaluate the influence of this type of freezing method and of the frozen storage of samples on the main physicochemical, biochemical, rheological and structural properties of Mozzarella cheese. In the main experimental design, cheese slabs (dimensions: 2x10x10 cm3) were immersed in 23% NaCl solutions (control samples: 4ºC, 90 min; frozen and frozen-stored samples: -15ºC, 180 min). The frozen-stored samples were stored at -20ºC for 2 months and then thawed at 4ºC. The samples were stored at 4ºC and assayed at 1, 7, 14, 20, 27, 34, and 41 days to evaluate physicochemical, biochemical, rheological and structural properties. Although the immersion freezing of Mozzarella cheese affects some of the studied parameters, the differences observed were small. Therefore, it was considered that the immersion freezing could be useful for the manufacture and preservation of Mozzarella cheese.Palabras clave – provistas por el repositorio digital
