A by-product in the production of semolina from durum wheat. It is used for American noodles, some types of pasta, and occasionally in specialty breads.

Basic Egg Facts



Air Cell

The empty space between the white and shell at the large end of the egg.



When an egg is first laid, it is warm. As it cools, the contents contract and the inner shell membrane separates from the outer shell membrane to form the air cell.



The candler uses the size of the air cell as one basis for determining grade. In Grade AA eggs, the air cell may not exceed 1/8-inch in depth and is about the size of a dime. The air cell of Grade A eggs may exceed 3/16-inch in depth. For Grade B eggs, there is no limit on air cell size.



As the egg ages, moisture and carbon dioxide leave through the pores of the shell, air enters to replace them and the air cell becomes larger.



Although the air cell usually forms in the large end of the egg, it occasionally moves freely toward the uppermost point of the egg as the egg is rotated. It is then called a free or floating air cell. If the main air cell ruptures, resulting in one or more small separate air bubbles floating beneath the main air cell, it is known as a bubbly air cell.



You can see the air cell in the flattened end of a peeled, hard-cooked egg.

Albumen

Also known as egg white. Albumen accounts for most of an egg's liquid weight, about 67%. It contains more than half the egg's total protein, niacin, riboflavin, chlorine, magnesium, potassium, sodium and sulfur. The albumen consists of 4 alternating layers of thick and thin consistencies. From the yolk outward, they are designated as the inner thick or chalaziferous white, the inner thin white, the outer thick white and the outer thin white. Egg white tends to thin out as an egg ages because its protein changes in character. That's why fresh eggs sit up tall and firm in the pan while older ones tend to spread out.



Albumen is more opalescent than truly white. The cloudy appearance comes from carbon dioxide. As the egg ages, carbon dioxide escapes, so the albumen of older eggs is more transparent than that of fresher eggs.



When egg albumen is beaten vigorously, it foams and increases in volume 6 to 8 times. Egg foams are essential for making souffles, meringues, puffy omelets, and angel food and sponge cakes.



The yolk or yellow portion makes up about 33% of the liquid weight of the egg. It contains all of the fat in the egg and a little less than half of the protein.



With the exception of riboflavin and niacin, the yolk contains a higher proportion of the egg's vitamins than the white. All of the egg's vitamins A, D and E are in the yolk. Egg yolks are one of the few foods naturally containing vitamin D.



The yolk also contains more phosphorus, manganese, iron, iodine, copper, and calcium than the white, and it contains all of the zinc. The yolk of a Large egg contains about 59 calories.



Double-yolked eggs are often produced by young hens whose egg production cycles are not yet completely synchronized. They're often produced, too, by hens who are old enough to produce Extra Large eggs. Genetics is a factor, also. Occasionally a hen will produce double-yolked eggs throughout her egg-laying career. It is rare, but not unusual, for a young hen to produce an egg with no yolk at all.

Vitamin B3



Also called Nicotinic Acid, Niacinamide, Nicotinic.



Acts as a co-enzyme in the release of energy from carbohydrates. Also needed to help breakdown fats and proteins. Aids in formation of red blood cells.

Since the 1950's doctors have used nicotinic acid to treat high cholesterol. Niacin is the only drug available that both substantially lowers the "bad" lipids (LDL), and increases the "good"(HDL) cholesterol. The reason this vitamin is not in the forefront of cholesterol therapy is because many people treated with high doses of niacin experience bothersome side effects such as; facial flushing, nausea, stomach pain, diarrhea and much more serious, liver damage.



Milk, eggs, meats (especially liver), chicken, fish, and most other protein-rich foods contain a significant amout of niacin. Also in smaller amounts in coffee and tea.



Dificiency is very rare in modern countries. Symptoms include: Pellagra (diarrhea, dermatitis, and dementia) Less severe symptoms of deficiency include irritability, loss of appetite, weekness and swollen tongue.

or iron, iron sulfate, Used in the food industry as a carrier for iron.



Iron in the body works with proteins that release energy in metabolism such as hemoglobin, which carries oxygen in the blood stream. Also involved in the making of ammino acids, hormones, and neurotransmitters.

Iron can be found in meats, poultry, and fish and many fortified foods. Fruits, vegetables and juices also provide some iron.

Iron deficiency symptoms include; anemia, inability to concentrate, weakness, fatigue, pallor, being out of breath after small exertion, cold hands and feet. Some people may develop a smooth round tongue, and have difficulty swallowing.



Symptoms of overload include: nausea, vomiting, diarrhea, rapid heartbeat, dizziness, shock and even death.



***Parents should be warned that iron supplements and multivitamins containing iron are the second most common cause of poisoning in young children in the U.S. (Aspirin is the first) The lethal dose of ferrous sulfate for a 2-year-old is only 3g.***

Vitamin B-1, Perfectly safe, despite adding minuscule amounts of nitrate to our food.

Vitamin B2, or riboflavin, is required to complete several reactions in the energy cycle. Reddening of the lips with cracks at the corners of the mouth, inflammation of the tongue, and a greasy, scaly inflammation of the skin are common symptoms of deficiency.Riboflavin (B2)- Classic riboflavin deficiency involves the lips, tongue, eyes, skin and nervous system. Vision changes, cheliosis (tiny lesions in the mouth or cracks in the corners of the mouth) tongue inflammation and discomfort eating or swallowing.



Riboflavin?s role in the body involves the metabolism of fats and proteins. Enzymes influenced by riboflavin are absolutely necessary to transport oxygen to the cells. A decrease in this vitamin can result in fatigue. New research indicates that migraine headache sufferers may benefit by riboflavin. 400mgs.day have been shown to lessen the incidence of migraines.



Required for red blood cell formation, antibody production, cell respiration and growth. Important for good muscle tone. Involved in metabolism of protein, protein fats, and carbohydrates. Necessary for good vision, skin, hair and nails.

Folic acid is the synthetic form of the B vitamin folate. Folic acid is necessary for the synthesis of nucleic acids and the formation of red blood cells. Folic-acid deficiency most commonly causes folic-acid-deficiency anemia. Symptoms include gastrointestinal problems, such as sore tongue, cracks at the corners of the mouth, diarrhea, and ulceration of the stomach and intestines. Large doses of folic acid can cause convulsions and other nervous-system problems.

The Food and Drug Administration (FDA) regulations require enriched grain products to contain this essential vitamin.



Current studies have discovered a link between folic acid and brain function in older people. The study divided 818 people ages 50 to 75 to take either a vitamin containing 800 micrograms of folic acid a day, or a dummy pill, for three years.



On memory tests, the supplement users had scores comparable to people 5.5 years younger, Durga said. On tests of cognitive speed, the folic acid helped users perform as well as people 1.9 years younger.
