RAKOV, D., 2005. Changes in nitrogen fractions during ripening of white brine cheese from cow milk, depending on the pasteurization of the milk and the conditions of coagulation. Bulg. J. Agric. Sci., 11: 411-414
The changes in nitrogen fractions (nitrogen in the dry matter, non casein nitrogen / total nitrogen - NCN/TN, non protein nitrogen / total nitrogen - NPN/TN), during ripening of white brine cheese from cow milk pasteurized at 75°C for 10 min and 85°C for 10 min and coagulated at pH=6.40 and pH=6.25, with the same amount of starter lactic bacteria CaCl2 and enzyme was studied.
The obtained results are showing higher values of NCN/TN and NPN/TN at all stages for the cheese made from milk pasteurized at 85°C for 10 min and coagulated at higher acidity.
