Fresh cheese production on the basis of milk-protein coaggregates

Two variants of fresh cheese were prepared: cheese prepared from milk heated at 650C for 30 minutes (control samples) and those prepared from milk heated for 10 minutes at 850C (experimental samples). Second method caused the protein co aggregates formation. Results of these investigations suggested that the whey obtained during fresh cheese production from co aggregates had considerable lower total nitrogen content (0.0601%) and milk fat content (0.08%). These values represented 46.37% and 33.33% of the control samples respectively. Also, dry matter of experimental whey samples was lower for 3.72% than in the whey of control samples. The cheese prepared on the basis of co aggregates had for 5.11% lower total solids content than control samples. The average values of these and control samples were 28.38% and 33.49% respectively. This may be due to protein co aggregates properties and the different structure of cheese curd. Disregarding to the higher utilization of the milk fat, the lower milk fat content in total solids content of experimental cheese is the result of higher participation of total nitrogen.
