Milk samples with low (L-SCC, 130,000/ml), medium (M-SCC, 1,040,000/ml) and high(H-SCC, 3,120,000/ml) Somatic Cell Counts (SCC) were obtained from a dairy farm. In order to evaluate the quality's changes of Low-fat mozzarella cheese with different SCC during ripening period, the change of texture properties, microstructure were measured. With the increase of somatic cells in milk, the structure of the cheese became worse.
