Skimmed  milk  is  essentially  whole  milk  with  the  larger  part  of 
its  fat  removed.  By  separation  with  shallow  pans  the  fat  content  is 
from  054  to  1 -co  per  cent.;  with  deep  pans,  from  0-43  to  1-05  per 
cent.,  and  with  the  modern  centrifugal  separators,  from  010  to  o  25 
per  cent.  (Vieth  ;  quoted  by  Allen.)
