204 CHEMICAL COMPOSITION 
Specific Gravity.—The specific gravity of sweetened con- 
densed milk falls within the limits of 1.24 to 1.35. Foreign 
brands average somewhat higher in specific gravity than Amer- 
ican 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 quart of condensed milk and contain- 
ing about 9 per cent. fat and 40 per cent. cane sugar, has a speci- 
fic gravity of about from 1.28 to 1.29. The specific gravity of 
sweetened condensed skim milk may go as high as 1.35, and, if it 
contains an excess of cane sugar, it may be still higher.
