The additional serum solids slightly decreased the overrun and retarded drainage. These effects became more pronounced when the serum solids content reached 9 percent and over. Increasing the serum solids with skim milk powder slightly decreased the percentage of fat in the drainage, while the condensed skim mil had no definite effect on serum drainage. These results indicate that the benefits derived by increasing the serum solids content of 30 percent cream to 11 percent are not great enough to justify the procedure.
