The quality of cassia cinnamon is proportionate to the number of bast cells present. The very inferior grades show few bast cells, which indicates that the outer older bark tissue predominates. Cassia could readily be graded according to the bast cell count. The organoleptic tests, especially taste and odor, are also valuable guides to quality. |
