ABSTRACT 



A statistical analysis has been made, as a supplement to D, S. Fish 

 and Wildlife Service Research Report k^, Preparation of a Dry Product 

 from Condensed Menhaden Solubles , 



Simple correlation studies show that k of 10 chemical and physical 

 characteristics are important in preparing suitable dry condensed solubles. 

 These are ammonia, corrected protein content, total ash and water insoluble 

 matter, and desirable limits are suggested for each. 



Multiple correlation studies of other selected data show that the 

 specific gravity of condensed solubles is largely determined by its total 

 ash and fat content. Dry solids content and the refractive index or spe- 

 cific gravity are not correlated either separately or in combination. 

 The study indicates that the variability in composition of condensed 

 solubles does not account for either the extreme variation in viscosity 

 of the condensed solubles or for differences in moisture-absorptive char- 

 acteristics of the related dry solubles. 



By means of an analysis of variance it was shown that the solubles 

 produced by plants in the South Atlantic and Gulf of Mexico areas differed 

 in composition from the product of plants in the Central Atlantic area. 

 Otherwise, there were not sufficient data to permit determination of the 

 effect of type of plant or of the month of production upon the properties 

 of the condensed solubles.
