Ripe and Unripe Bananas, by R. Reich, in Ztschr. Untersuch. 

 Xahr. u. G^nussmtl., \'ol. 22, Xo. 4. 

 In this article, according to a recent Experiment Station Record, 

 "analyses are reported of dried ripe bananas of different sorts, un- 

 ripe bananas, banana flour, skins from ripe and unripe bananas, 

 and fresh bananas of different sorts. The conclusion is reached 

 that in the case of bananas which are shipped green and then 

 allowed to ripen, the transfonnation of starch into sugar takes 

 place normally. The inversion of saccharose, however, proceeds 

 slowly under such conditions. It appears further that bananas in 

 which the saccharose content is higher than the invert sugar are to 

 be regarded as 'unripe.' The flavor is flat, and there is little or 

 no aroma."
