Since the reducing sugars and the non-sugars in a juice must occur in 

 the molasses in the same relative proportions, the question at once arises 

 as to what is the effect, if any, of these bodies on the quantity of sugar that 

 remains in the molasses. A typical beet sugar molasses formed in the 

 absence of reducing sugars contains about 45 per cent, of sugar, whereas 

 a typical cane molasses contains about 30 per cent., together with about 

 20 per cent, of reducing sugars. Cane molasses is, however, much more 

 variable in composition than beet molasses, and a casual inspection of a 

 series of analyses will show that generally a high percentage of reducing 

 sugars is accompanied by a lower percentage of cane sugar. From a large 

 number of analyses of molasses made by Geerligs, Peck, Deerr and others,, 

 the writer has obtained the average analyses of molasses divided into the 

 following categories as regards the reducing sugars : Below 14 per cent. ; 

 between 14 and 18 per cent. ; between 18 and 21 per cent. ; between 21 and 

 24 per cent. ; between 24 and 27 per cent. ; over 27 per cent. The results 

 appear in the annexed table, all being calculated to 80 per cent, dry 

 matter. 



* Carbonation molasses. 



f The potash in Hawaiian molasses is of the order 4 per cent, as in Javan molasses, but the sulphates are often 

 present in a quantity from two to three times as great as in Javan molasses.
