A Study on the Physico-chemical Properties of Abnormal Milk

When abormal milk produced Kyungkido area was anlyzed for abnormal milk, the ratio of the abnormal milk for the total was higher in June, July and August compared with other months and the average of abnormal mik produced in the three months was 1.875%. Especially the percentage of abnormal milk was highest in June as 2.5. %. The range of fat content of abnormal milk is the ratio of nonprotein solble in 12% TCA liberated from normal and abnormal milk by rennet treatment showed almost same tendency, it was observed that abnormal milk was coagulated more slowly than normal milk. In this experiment, protein content of No. 1 and No. 2 abnormal milk was 3.5% and 3.7%, respectively and non-protein nitorogen content was 24.8 mg per 100 ml of milk. The financial loss by abnormal milk through alcohol test, specific gravity test and the rate of butter fat etc, have reached 148, 959, 307 won per one year(1975.10. 1-1976. 9. 30)
