Ethnobotanical Leaflets Starch Research Page


Winton (1906) records that the forms of the grains are so numerous, even in the same variety, as to forbid accurate classification, but that the following are the more striking:

1. Globular. The starch of the peanut and some grains of maize.

2. Lenticular. The large grains of wheat, rye, and barley.

3. Ellipsoidal. The starch of legumes.

4. Ovoid or pear-shaped. The starch of potato, canna, Bermuda arrowroot, yam, and banana.

5. Truncated. Most of the grains of cassava, batata, and sago.

6. Polygonal. The starch of maize, rice, oats, and buckwheat.
