CHKMICAI, COMPOSITION 



brands average higher in specific gravity than American brands. 

 The specific gravity of sweetened condensed milk is controlled 

 by the degree of condensation, the per cent, of fat and the per 

 cent, of cane sugar. Milk condensed at the ratio of about 

 2.5 parts of fresh milk to 1 part of condensed milk and contain- 

 ing about 9 per cent fat and 40 per cent cane sugar, has a specific 

 gravity of about from 1.28 to 1.29. The specific gravity of sweet- 

 ened condensed skim milk may go as high as 1.35, and, if it con- 

 tains an excess of cane sugar, it may be still higher.
