Buckwheat Flour Organic
The buckwheat plant is entirely different from other grains and is not a grass. It is a summer annual with rather coarse, branched stems and large, broadly arrow-shaped leaves. Flower panicles and leaves rise from the nodes, both on the main stem and branches. Growth habit is indeterminate with flowers opening throughout a long season, so the seed crop does not mature at one time. The seed is partially but not entirely enclosed by adhering flower parts during development. Buckwheat is usually seeded only after the ground is thoroughly warm in early summer. Plants will begin blooming in about 40 days from seeding and first seeds mature about 35 days later. Harvesting is done when a substantial part of the seed is ripe. Fields are then mowed and plants are stacked to dry before they can be threshed. Seeds are pointed, broad at the base, and triangular to nearly round in cross section. They vary in size in different kinds from about 4 mm at maximum width and 6 mm. long to 2 mm. wide and 4 mm. long. The seed consists of an outer layer or hull, an inner layer, the seed coat proper, and within this a starchy endosperm and the germ. In milling the hull, which comprises 18 to 20 percent of the whole grain weight, is first removed. A second milling removes most of the seed coat or "middlings" which comprise 4 to 18 percent of the whole grain weight - depending on how completely the seed coat tissues are removed. In most buckwheat flour some of the seed coat particles remain, resulting in a light brown color. More complete milling results in a white flour. Silverhull plants are smaller than Japanese with smaller leaves. The seeds are small, nearly round in cross section, glossy and gray in color. The hulls are thinner than in Japanese. A kind tenned Common Gray is probably identical with Silverhull. Tartary buckwheat has small seeds, nearly round in cross section. Color varies from gray to black. The hull may be smooth to rough and spiny. Leaves are relatively small, narrow and arrow-shaped. Plants may be almost viny in habit. The flour from Tartary buckwheat is inferior to that from Japanese or Silverhull. Wing-seeded buckwheat is similar to Japanese except that the hull at the angles of the seed is extended to form a wing. It is not normally planted, but may be present as a mixture in other kinds. ses of Buckwheat Most of the buckwheat grown in the United States is milled into flour which is used largely in pancakes. For pancakes the flour is usually blended with that from other grains. Whole buckwheat grain may be used in poultry scratch feed mixtures. The middlings from milling make good livestock feed as they are high in protein. The straw is higher in protein but lower in digestable carbohydrates than grass grain straw. The buckwheat plant is an excellent honey source as the blossoms are rich in nectar, and blooming continues into the fall months. Some beekeepers plant buckwheat primarily for such use.
