Spaeth, E., points out that among the more common adulterants 
of ginger are flour, curcuma, linseed and rapeseed cake, cayenne 
pepper hulls and extracted ginger. Commercially satisfactory ginger 
should not be wholly or partly extracted, should have an agreeable, 
spicy odor and a burning taste. The ash of the air dry drug should 
not exceed 10 per cent, and the portion insoluble in 8 per cent hydro- 
chloric acid should not exceed 3 per cent. — Ztschr. f. Unters. d. Nahr.
