1, The following significant simple correlations were found i 



a. Total ash and amnonia were positively correlated (low value 

 for desirable effect), and corrected protein and water in- 

 soluble matter were negatively correlated (high value for 

 desirable effect) to the Suitability Factor, 



b. Fat content of condensed solubles was positively correlated 

 to oil separation during drying, 



c. Ammonia content was positively correlated to the development 

 of objectionable vapor odors during diTing, 



d. Ammonia content was positively correlated (but at a barely 

 significant level) to hot plasticity of the dry solubles on 

 the dryer drums, 



2, The multiple correlation studies indicated: 



a. Total ash was positively correlated and fat content negatively 

 correlated to the specific gravity of the condensed solubles. 

 The combination of these two factors accounted for almost all 

 the variability in specific gravity, 



b. Although four selected characteristic components, namely ammonia, 

 corrected protein, fat, and total ash, were individually not 

 significsmtly correlated to moisture absorption of the dried 

 solubles J collectively, they almost had a significsint correla- 

 tion at the 5-percent level, 



3, An analysis of vsiriance indicated: 



a. The location of plant had an effect on dry solids j lower values 

 being observed in the three Southern areas, 



b. Ammonia was significantly higher, and fat lower in solubles pro- 

 duced in hot-air evaporators as compared with those produced in 

 multistage vacuum evaporators, 



Co Viscosity was significantly higher in condensed solubles sampled 

 directly from the evaporators, 



Uo The statistical analysis showed that there were no significant 

 correlations in the following data: 



a. Neither the specific gravity nor the refractive index was cor- 

 related to the total solids content of the condensed solubles.
