X Here, again, the bleaching does not seem to affect the power of the 
digestive ferment. 
To sum up the results — no indication has been found that when carried 
on under the same conditions, the power of the digestive enzymes is 
affected in any way by changes in wheat flour due to the nitrogen peroxid 
bleaching process. Unless the conditions are carefully kept the same 
the results of digestive tests may differ widely. .
