Definition of Milk Powder. 



The federal standards of milk powder are as fol- 

 lows : " Dried milk is the product resulting from the 

 removal of water from milk, and contains, all toler- 

 ances being allowed for, not less than twenty-six 

 per cent (26.0%) of milk fat and not more than five 

 per cent (5.0%) of moisture. 



" Dried skimmed milk is the product resulting 

 from the removal of water from skimmed milk and 

 contains, all tolerances being allowed for, not more 

 than five per cent (5.0%) of moisture." 



Much of the milk powder made in this country is 

 used in the warm states, where it is difficult to pro- 

 duce milk. Considerable quantities are exported to 

 tropical countries. Many ice-cream plants use it 

 to standardize the mix. Bakers also use it.
