An
interesting Fact About Grain: Grain
crops are also known as cereal crops. This comes from the Greek goddess of farming,
Ceres. The use of wheat dates back 75,000 years. WHAT
ARE GRAINS? Grains are the seed heads of grass plants. Over time,
certain species of grasses were found to produce seeds that people preferred over
others. Major grain categories in the world are wheat, rice, corn, barley, oats,
and rye. A kernel of wheat is composed of 3 main parts: 83% of the kernel is the
starchy interior called the endosperm; 14.5% of the kernel is the protective seed
coat called bran; and 2.5% of the kernel is the part of the seed that will germinate
a new plant called the embryo. HOW
MANY GRAINS DO WE PRODUCE? Wheat, Barley and oat are the most
common grain crops in the UK. Oats and barley are used mainly as animal feed,
but it is also used for molting and baking. Wheat is used both for human consumption
and livestock feed. Smaller amounts of rye, linseed sunflowers, lavender and now
even lupins are also grown. Dry field peas, one of the pulse crops are used for
both human and animal consumption. Wheat
Nutrients CarbohydrateComplex
Carbohydrate -- Wheat flour is a good source of complex carbohydrate, the
most efficient source of energy available to the human body. Fiber
-- Fiber is the indigestible carbohydrate in food which acts like a broom to sweep
our the digestive tract. One slice of whole wheat bread contains 1.5 grams of
dietary fiber; one slice of white bread contains 0.5 grams. ProteinWheat
foods are moderate sources of incomplete protein. This means that while wheat
and other cereal grains may contain all eight of the amino acids necessary for
good health, not all eight are found at adequate levels. However, combining wheat
or other cereal grains with animal proteins or legumes makes the grain protein
complete. Within the cereal group, wheat contains more protein than rice or corn. FatFats
account for 2 to 23 percent of wheat foods, although wheat alone contains very
little fat. Most often, the fat content in wheat foods results from fat added
in production, such as the oil or shortening found in many baked or fried wheat
foods. Bread and pasta products are low-fat foods because the by weight, is wheat
flour. Other
Vitamins And MineralsThiamine
-- One of the essential B-vitamins needed daily for good appetite, digestion and
healthy nerves. Wheat foods are a good source of thiamine. Niacin
-- A B-vitamin essential for the efficient use of protein by the body. Wheat foods
are a good source of niacin. Iron
-- Vital to nutritional. Wheat foods are a reliable source of iron for normal
dietary needs. Zinc
-- Important for skin healing and growth properties. Wheat foods are a good source
of zinc. Riboflavin
-- Essential for growth and good vision. Wheat foods are a fair source of riboflavin. Trace
Minerals -- Wheat foods are a good source of selenium and magnesium, nutrients
essential to good health. Wheat
Flours All-purpose
Flour All-purpose
flour is the finely ground endosperm of the wheat kernel separated from the bran
and germ during the milling process. All-purpose flour is made from hard wheat's
or a combination of soft and hard wheat from which the home baker can make a complete
range of satisfactory baked products such as yeast breads, cakes, cookies, pastries
and noodles. Enriched
All-purpose Flour has iron and B-vitamins added in amounts equal to or exceeding
that of whole wheat flour. Bleached
Enriched All-purpose Flour is treated with chlorine to mature the flour,
condition the gluten and improve the baking quality. The chlorine evaporates and
does not destroy the nutrients but does reduce the risk of spoilage or contamination. Unbleached
Enriched All-purpose Flour is bleached by oxygen in the air during an aging
process and is off-white in color. Nutritionally, bleached and unbleached flour
are the same. Bread
Flour Bread
flour, from the endosperm of the wheat kernel, is milled primarily for commercial
bakers but is also available at retail outlets. Although similar to all-purpose
flour, it has a greater gluten strength and generally is used for yeast breads. Self-Rising
Flour Self-rising
flour is an all-purpose flour with salt and leavening added. One cup of self-rising
flour contains 1 1/2 teaspoons baking powder and 1/2 teaspoon salt. Self-rising
flour can be substituted for all-purpose flour in a recipe by reducing salt and
baking powder according to those proportions. Whole
Wheat Flour Whole
wheat flour is a course-textured flour ground from the entire wheat kernel and
thus contains the bran, germ and endosperm. The presence of bran reduces gluten
development. Baked products made from whole wheat flour tend to be heavier and
denser than those made from white flour. Other
Flours Cake
Flour - Milled from soft wheat. Especially suitable for cakes, cookies, crackers
and pastries. Low in protein and gluten. Pastry
Flour - Milled from a soft, low gluten wheat. Comparable in protein but lower
in starch than cake flour. Gluten
Flour - Used by bakers in combination with flours having a low protein content
because it improves the baking quality and produces gluten bread of high protein
content. Semolina-
Coarsely ground endosperm of durum wheat. High in protein. Used in high quality
pasta products. Durum
Flour - Byproduct of semolina production. Used to make commercial noodles. Farina
- Coarsely ground endosperm of hard wheat's. Prime ingredient in many breakfast
cereals. Also used in the production of inexpensive pasta.
INFORMATION
ABOUT THE WHEAT KERNEL The
wheat kernel, sometimes called the wheat berry, is the seed from which the wheat
plant grows. Each tiny seed contains three distinct parts that are separated during
the milling process to produce flour. The kernel of wheat is a storehouse of nutrients
essential to the human diet. Endosperm ..About
83 percent of the kernel weight. It is the source of white flour. The endosperm
contains the greatest share of the protein in the whole kernel, carbohydrates,
iron as well as many B-complex vitamins, such as riboflavin, niacin, and thiamine. Bran ..About
14 1/2 percent of the kernel weight. Bran is included in whole wheat flour and
is also available separately. Of the nutrients in whole wheat, the bran contains
a small amount of protein, larger quantities of the B-complex vitamins listed
above, trace minerals, and indigestible cellulose material also called dietary
flour. Germ ..About
2 1/2 percent of the kernel weight. The germ is the embryo or sprouting section
of the seed, usually separated because of the fat that limits the keeping quality
of flour. Of the nutrients in whole wheat, the germ contains minimal quantities
of protein, but a greater share of B-complex vitamins and trace minerals. Wheat
germ can be purchased separately and is included in whole wheat flour.

This cereal grass was known to Greeks, Romans, Chinese, and Egyptians and was
cultivated as early as any grain on earth. Although it had become the chief bread
material in Europe by the 16th century, its notoriously low gluten and elasticity
made it welcome for filling the belly, but it never brought much joy as a bread
or baked in any way. The decoction of barley water so ridiculed in the Mary
Poppins movie was actually a masterstroke of medical wizardry on the part of the
ancient Greek doctor Hippocrates. He prescribed it for many ailments, sometimes
with the grain, sometimes as a filtered liquid. It's easily made: just boil 2
teaspoons of pearl barley (its other form is hulled barley) in a 5 or so cups
of water. When the barley is completely cooked, remove from the heat, let sit
a minute, then strain, pressing the solids well. Perhaps its greatest claim
to fame is its transformation into beer, begun by first malting the grains that
is moistening them, letting them sprout, then roasting them. HOW
ARE GRAINS PRODUCED? Through plant breeding, scientists develop
new varieties which are higher yielding and have more disease resistance. Farmers
who specialize in seed production multiply seed of these varieties for commercial
farmers to plant. Farmers prepare the fields for planting. Farmers plant in the
spring and harvest in August and September. They also plant winter crops in September
or October. Which are harvested in late July and early August. Before
planting a crop, farmers prepare their fields for seeding. This may entail cultivating
the soil, usually applying fertilizers and then seeding the crop using a seed
drill. If required, herbicides for weed control are used. When
the crop ripens, it is harvested. Wheat, for example, is ready to be harvested
when it is about 1m high and the color changes from green to golden and the grain
is around 15 percent mousture. A head of wheat contains 30 to 65 kernels of grain.
A combine is used to separate the seeds from the chaff and straw. Harvested grain
is stored in granaries and may require drying or cooling to do so safely. It is
important to maintain specific moisture levels and temperatures in grain to ensure
that it does not become mouldy. WHAT
HAPPENS AFTER THE GRAINS LEAVE THE FARM? From the farm, most of
the grain is taken to grain stores where it is cleaned and graded ready for sale.
Wheat is graded based on the type of wheat, moisture content, foreign materials,
disease or weather damage. Wheat
and barley are exported. Feed growers have a number of different marketing channels. Most
of the wheat eaten by people is milled, which means it is ground into flour. The
process of milling involves cleaning the wheat and removing all foreign materials.
The wheat is then conditioned by adding moisture so that the bran can be removed
easily. Finally, the grain is milled by passing it through large rollers to grind
the wheat. For white flour the bran is sifted out. Because the bran contains many
nutrients, when it is removed flour loses much of its nutritive value. In UK the
enrichment of white flour by replacing these nutrients has been required by law.
In the last few years, an increasing amount of wheat is milled into whole wheat
flour rather than white. Barley and oats are usually processed into animal feed.
Barley is also malted for use in beer making. WHAT
DOES GRAIN LOOK LIKE WHEN I USE IT? Ground grain is called flour.
The most common type of flour in the UK is wheat flour. This is used to make bread,
pizza dough, and pastries. A special kind of hard wheat, called durum wheat, is
used to make pasta. We also eat whole grains when we eat porridge, such as oatmeal.
High quality barley is malted (sprouted and dried) and used to make beer. Dried
field peas are used in such dishes as pea soup. Grains
are also used for animal feed. There are feed mills throughout UK that make livestock
feed. Many livestock farmers also mill their own feed. Grains
are a good source of carbohydrates and protein for us and for other animals. In
wheat, the endosperm contains starch, the bran contain minerals and vitamins,
and the embryo contains protein, fat and vitamins. WHAT
CHALLENGES DOES THE GRAIN PRODUCER FACE? Taking care of the soil
is very important for crop growers. Special seeding methods can help prevent erosion
of top soil from wind and water. Traditionally, the stubble from the previous
year's crop was destroyed and the field was cultivated until a smooth seed bed
was prepared. To prevent erosion of topsoil and to save on costs, however, farmers
are using different methods. Some farmers turn the stubble from the previous year
back into the ground. The roots help hold the top soil in place. Wheat roots can
penetrate the soil to a depth of 1m. Other farmers use a special seeding technique
called minimum or no-till and plant this year's crop into the stubble of last
year's crop. This is done by a machine which cuts a slice in the ground, drops
in a seed, and covers the seed. This also saves energy and labour because it reduces
the number of times that the farmer has to work the field. WHO'S
