Skim milk with 9.15% DM was heat treated at 85 deg C/10 min, 90 deg C/10 min and 95 deg C/10 min, respectively. Untreated milk was used as control. Milk samples were coagulated by glucono-delta-lactone (GDL) at the temperature of 45 deg C until pH 4.60 was reached. Untreated milk had the longest time of acidification. Nitrogen matter content in sera obtained from untreated milk was 79.40 mg%. Sera samples obtained from milk heat teated at 85 deg C/10 min, 90 deg C/10 min and 95 deg C/10 min had 47.80 mg%, 45.00 mg% and 43.50 mg% of nitrogen matter, respectively. Distribution of nitrogen matter from untreated milk to milk sera was 12.70%, while distribution of nitrogen matter from milk heat treated at 85 deg C/10 min, 90 deg C/10 min and 95 deg C/10 min to sera samples, were 6.95%, 6.57% and 6.22%, respectively.
