values. The percentage of added milk, even if relatively low, caused changes in the compositional and nutri-tional characteristics of the innovative products (Table 2). The composition of milk was 3.6% protein, 4.4% fat, and 4.0% lactose for CC milk; 4.0% protein, 4.6% fat, and 4.3% lactose for CE milk; and 3.5% protein, 4.1% fat, and 4.3% lactose for CG milk. After production and during ripening, the CG sample had a significantly lower fat content and higher ash content than the CC sample. The lower fat content may be associated with the different composition of the initial mixed milk and with a higher fat loss in the hot water used to stretch the curd, caused by the smaller fat globules in goat milk. The different added milks had no significant ef-fect on cheese proteins. Lactose and galactose showed different values among samples, because of different microbial activities and, at d 60 of ripening, they were absent in all samples. In all samples, the change in color (L*, a*, b*), monitored on the surface and in the inner part of cheeses, did not show significant changes (Table 2)
