Condensed Milk and Milk Powder 



amount of sucrose in milk does not appreciably affect the power of 

 the milk to dissolve milk sugar, nor does the per cent, of lactose 

 present materially affect the power of the milk to dissolve sucrose. 

 Specific Gravity. — The specific gravity of sweetened con- 

 densed milk falls within the limits of 1.24 to 1.35. Foreign brands 

 average higher in specific gravity than American brands. The spe- 

 cific 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 containing about 9 per cent, fat and 40 

 per cent, cane sugar, has a specific gravity of 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.
