CONCLUSION 



The original data published in Research Report kS show that the 32 

 randomly collected samples of condensed solubles differed considerably 

 in chemical and physical characteristics, and produced dry solubles of 

 widely varying properties. No single characteristic of the condensed 

 solubles showed a degree of correlation to the desired properties of 

 a dry product that would justify its selection as a criterion of choice 

 of condensed solubles for use in producing dry solubles. The statistical 

 analyses suggest, however, that condensed solubles with low ammonia and 

 high corrected protein content, and low ash and high water insoluble 

 matter content would diy easily and produce a satisfactory dry product. 

 The first two relate to the freshness of the stickwater from which the 

 condensed solubles are produced. Specifically, an ammonia content less 

 that 1,25 percent and total ash content less than 8,5 percent; and cor- 

 rected protein content more than 29 percent and water insoluble matter 

 more than haS percent would be the suggested minima and maxima. It has 

 not been possible to test the practical aspects of this conclusion since 

 none of the producing plants is equipped with drum drying equipment at 

 the present time*
