DATE SUGAR INDUSTRY IN BENGAL. 



DETERIORATION OF DATE SUGARS ON STORAGE. 



Some date sugars which were analysed in June 1911, were stored 

 away in glass stoppered bottles. On opening the bottles in April 

 1912 all the samples had a more or less offensive smell and all the 

 sugars were again analysed. It was found that a good deal of change 

 had gone on in their composition. The results are set out in the 

 accompanying tables.

A fresh set of samples of date sugar made in 1911-12 season were 

 analysed and put up in glass stoppered bottles on May 5th, 1912. 

 They were again analysed on 18th June 1912. The results are here 

 set out.

The table shews that even in such a short period as 6 weeks 

 these native prepared sugars have deteriorated to a large extent. 

 Greig Smith 1 and Owen 2 have observed this deterioration of raw 

 sugars on storage. We have not examined the nature of the change, 

 but it is probably bacterial as was shewn by Greig Smith in the case 

 of Australian raw sugar.
