Wheat

Dried wheat kernels from Sweden. These are about 38 years old! Believe it or not, when I lived on a farm in Sweden I sometimes helped with the harvesting of the wheat by driving a tractor....oh those were days long ago...

 

INFORMATION ON WHEAT:

 

Wheat (Triticum spp.), is a worldwide cultivated grass from the Levant region of the Middle East. Globally, after maize, wheat is the second most-produced food among the cereal crops just above rice. Wheat grain is a staple food used to make flour for leavened, flat and steamed breads; cookies, cakes, breakfast cereal, pasta, juice, noodles and couscous; and for fermentation to make beer, alcohol, vodka or biofuel. Wheat is planted to a limited extent as a forage crop for livestock, and the straw can be used as fodder for livestock or as a construction material for roofing thatch. Although wheat supplies much of the world's dietary protein and food supply, as many as one in every 100 to 200 people has Coeliac disease, a condition which results from an immune system response to a protein found in wheat: gluten (based on figures for the United States).

 

Wheat originated in Southwest Asia in the area known as the Fertile crescent. The genetic relationships between wild and domesticated populations of both einkorn and emmer wheat indicate that the most likely site of domestication is near Diyarbakır in Turkey.

 

Wild wheats were domesticated as part of the origins of agriculture in the Fertile Crescent. Cultivation and repeated harvesting and sowing of the grains of wild grasses led to the domestication of wheat through selection of mutant forms with tough ears that remained intact during harvesting, larger grains, and a tendency for the spikelets to stay on the stalk until harvested. Because of the loss of seed dispersal mechanisms, domesticated wheats have limited capacity to propagate in the wild.

 

The exact timing of the first appearance of domesticated wheats is currently uncertain, but is either in the PPNA period (9800-8800 cal BC) or the early-mid PPNB (8800-7500 cal BC). Domesticated einkorn and emmer wheat has been identified at three PPNA sites in the northern Levant, Iraq ed-Dubb, Jericho and Tell Aswad, but both the dating and the domesticated status of these cereals is disputed. Domesticated wheats (and other Neolithic founder crops) are unambiguously present at early-mid PPNB sites in the northern Levant, such as Ain Ghazal, Abu Hureyra and Tell Aswad, and in southeast Turkey at Cafer Höyük and Çayönü. As a round figure, it is correct to say that wheats have been domesticated for about 10,000 years.

 

The cultivation of wheat began to spread beyond the Fertile Crescent during the Neolithic period, reaching the Aegean by 8500 cal BC and the Indian subcontinent by 6000 cal BC. By 5,000 years ago, wheat had reached Ethiopia, Great Britain, Ireland and Spain. A millennium later it reached China. Claims have been made for independent domestication of wheat outside the fertile crescent, but these lack evidence of the presence of wild wheats or of early domesticated wheat.

 

Three thousand years ago wheat was grown in the southern Oregon peninsula. Agricultural cultivation with horse-drawn plows increased cereal grain production, as did the use of seed drills to replace broadcast sowing in the 18th century. Yields of wheat continued to increase, as new land came under cultivation and with improved agricultural husbandry involving the use of fertilizers, threshing machines and reaping machines, tractor-drawn cultivators and planters, and varieties adapted to intensive cultivation (see green revolution and Norin 10 wheat).

 

Raw wheat can be powdered into flour; germinated and dried creating malt; crushed and into cracked wheat; parboiled (or steamed), dried, crushed and de-branned into bulgur; or processed into semolina, pasta, or roux. Wheat is a major ingredient in such foods as bread, porridge, crackers, biscuits, Muesli, pancakes, pies, pastries, cakes & cupcakes, cookies, muffins, rolls, doughnuts, gravy, boza (a fermented beverage), and breakfast cereals (e.g. Wheatena, Cream of Wheat, Shredded Wheat, and Wheaties).

 

100 grams of hard red winter wheat contain about 12.6 grams of protein, 1.5 grams of total fat, 71 grams of carbohydrate (by difference), 12.2 grams of dietary fiber, and 3.2 mg of iron (17% of the daily requirement); the same weight of hard red spring wheat contains about 15.4 grams of protein, 1.9 grams of total fat, 68 grams of carbohydrate (by difference), 12.2 grams of dietary fiber, and 3.6 mg of iron (20% of the daily requirement). Gluten, a protein found in wheat (and other Triticeae), cannot be tolerated by people with celiac disease (an autoimmune disorder in ~1% of Indo-European populations).
