DATE SUGAR INDUSTRY IN BENGAL. 



The table shows the results of the analysis of three different 

 date juices side by side with an analysis of juice of red Mauritius 

 cane grown at Pusa and analysed at the same time under the same 

 conditions. 



The main constituent of the dry matter in date juice, as in the 

 case of cane juice, is sugar. The amount of the nitrogenous con- 

 stituents is smaller than in the cane juice examined, but 0*099% of 

 nitrogen in cane juice is abnormally high. Duplicate determinations, 

 however, were carried out. Geerligs 1 gives 0*036% of nitrogen as 

 an average figure for cane juice and says that it varies from 

 0*018 to 0*062, so that there is not much difference between the 

 nitrogen content of cane juice and date palm juice. 



Mineral matter in juice. Leather found for cane juice that the 

 mineral matter varied from 0*25 to 0*49. The ash of the date 

 palm juice seems rather less in amount than this. 



Pectin bodies. These were determined by precipitating 50 c.c. 

 of filtered juice with an equal volume of alcohol, filtering off on to a 

 tared filter, and after washing with alcohol, drying to constant 

 weight. \ 



An analysis carried out in this way gave 0*26% of pectin. 

 This precipitate of course would also include gum present in 

 the juice.
