Chemical and Proteolysis-Derived Changes during Long-Term
Proteolysis was observed in all milk types. However the degree of proteolysis was significantly higher in the lactose-hydrolyzed milk compared to the conventional and filtered milk. The proteins most prone to proteolysis were β-CN and α s1-CN which were clearly hydrolyzed after approximately 90 days of storage in the lactose-hydrolyzed milk.
