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.

This material is used in a variety of food applications including as a leavening agent in baked goods, a water retention agent for cooked meat products,and as a sequesterant (as in potato processing). Generally recognized as safe.

a common leavening agent used in baked goods. Used for fireproofing, in baking powder, and as an antirheumaticalso used as a fire retardant and in fertilizers.

AMMONIUM SULFATE is light-colored extended crystals, received as a result of production of caprolactam, in by-product-coking and acrylate industry.Ammonium sulfate's nitrogen can be very assimilated, besides nitrogen it contains sulfur, which is very important for nutrition of agriculture crops too.

Researchers at the USDA Human Nutrition Center (HNRCA) have found that blueberries rank #1 in antioxidant activity when compared to 40 other fresh fruits and vegetables. Antioxidants help neutralize harmful by-products of metabolism called "free radicals" that can lead to cancer and other age related diseases. Anthocyanin -- the pigment that makes the blueberries blue -- is thought to be responsible for this major health benefit.

In another USDA Human Nutrition Center (HNRCA) lab, neuroscientists discovered that feeding blueberries to laboratory rats slowed age-related loss in their mental capacity, a finding that has important implications for humans. Again, the high antioxidant activity of blueberries probably played a role.

A one cup serving of blueberries contains 16% DV of fiber. Blueberries are a source of Vitamins A and C, potassium and folate.

Blueberries are very low in fat and sodium.

– A concentrate is a form of substance which has had the majority of its base component, or solvent, removed. Typically this will be the removal of water from a solution or suspension such as the removal of water from fruit juice. The benefit of producing a concentrate is that of a reduction in weight for transportation as the concentrate can be re-constituted at the time of usage

There are over 1,000 varieties of this nutritious LEGUME, ranging in size from as small as a pea to as large as a cherry. Soybean pods, which are covered with a fine tawny to gray fuzz, range in color from tan to black. The beans themselves come in various combinations of red, yellow, green, brown and black. Their flavor is generally quite bland, which may explain why they weren't embraced by Western cultures until their nutritive value was discovered. Unlike other legumes, the soybean is low in carbohydrates and high in protein and desirable oil. Because they're inexpensive and nutrition-packed, soybeans are used to produce a wide variety of products

Omega-3's

Certain fatty fish, like salmon and tuna, contain the best source of heart-healthy omega-3 fatty acids. But certain plant foods, like flaxseed and soybeans, also contain these fatty acids. Soybeans are one of the best non-fish sources of essential omega-3 fatty acids, which may help reduce the risk of coronary heart disease. Compared to other beans like pinto beans and navy beans, soybeans have a higher fat content, but this fat contains these heart-healthy omega-3's.





Liquid soybean Oil is the primary ingredient in margarine.

Water is the most abundant nutrient in our body and plays an important transmission function in every body cell and tissue. Sixty percent of our body weight is water. The fact that you can live without food for a long period of time, even months, but live only for a few days without water is true. Under normal conditions, the body releases about one quart of water daily. Therefore, replacement to equal the losses is very important for survival.

Dehydration is the most common problem of water imbalance due to water losses and deprivation. The effects of dehydration on nutrition can adversely affect ones health. Dehydration is the major cause of ones diminished ability to perform during endurance activities. Body water is lost through the stomach, respiration, sweat, and the kidneys. It is recomended that 24oz of water a day should be taken. This amount can double or even triple with endurance type exercise.



A note about water: More and more evidence shows the benifit of being well hydrated.

Studies show that 75% of Americans are chronically dehydrated (likely applies to half the world's population), leading to possible health problems such as fatigue. In 37% of Americans, the thirst mechanism is so weak that it is often mistaken for hunger, leading to over-eating. Even MILD dehydration will slow down one's metabolism as much as 3%.



Bottled Water: Some types of bottled water are not subject to the same regulations as tap water. These are regulated as food products, and their regulations are largely related to sanitary food handling and processing practices. Bottled water manufacturers will provide a detailed report on the quality of their product to consumers who call to request it.

Soybean(s) Oil Partially Hydrogenated

Soybean Oil by itself is the 19% of oil extracted from the soybean. Partially hydrogenated is when hydrogen gas is pumped into the oil to fill in the unsaturated fat (“good fats”) bonds. However, through partial hydrogenation, the soybean oil takes a stiffer texture and the natural omega-3 fatty acids levels seen in natural soybean oil are lowered. This version of oil is therefore unhealthier to the consumer because of its unnatural use of hydrogenation which forms trans-fats that the body cannot breakdown. Trans-fats are solid fats produced from oil by unnatural methods and interfere with metabolic processes such as increasing LDL or “bad cholesterol.” Partially hydrogenated oils have a tendency to be used by food companies because of its cheapness, stability, improved texture, and ability to oxidize to provide a longer shelf life. People who are allergic to soy must be careful when reading the food labels for soybean oil. Consumption of soybean oil by those who are allergic to it can lead to discomfort or a more harmful reaction if not aware. Many of the essential fatty acids, antioxidants, and other positive components of the oil are lost through this process.

Salt is one of the most ubiquitous food ingredients around. Those who think of salt only as something used to perk up flavor might wonder what could possibly give this ingredient the level of importance it has gained through the ages. In reality, there is much more to this crystalline cube than first meets the eye.



Besides enhancing taste, salt has several other functions in food products. It acts as an antimicrobial or microbiological control agent. It contributes to certain chemical reactions that create a wide variety of food characteristics.



Sometimes the terms "salt" and "sodium" are used interchangeably, but technically this is not correct. "Salt" is sodium chloride. By weight, it is 40 percent sodium and 60 percent chloride.

Most foods and tap water contain sodium and chloride. Sodium is an essential nutrient, a mineral that the body cannot manufacture itself.

Because of sodium's importance to your body, the excretory and nervous systems guard against under-consumption of salt, which is a threat to your body's nerves and muscles. Other ions such as calcium, magnesium, and potassium are also very important. Concentrations of these ions are held in narrow ranges by the kidney.



The association between eating salt and the risk of blood pressure increasing is difficult to quantify. Some people are sensitive to changes in salt intake whereas others can adjust so that blood pressure does not rise at all.



Americans typically consume 4,000-8,000 mg each day, well above their daily needs. A goal for moderation for all adults, (including pregnancy and lactation) is approximately 2,400 mg of sodium per day.

A word about "Partially Hydrogenated" Oils:



It is now known that the process of hydrogenation creates "trans fatty acids" (TFAs), which are toxic entities that enter cell membranes, block utilization of essential fatty acids (EFAs) and impede cell functionality. TFAs also cause a rise in blood cholesterol. These substances are not present in natural oils.



Trans fat, which is also called hydrogenated or partially hydrogenated vegetable oil. Trans fat is found in margarine and shortening and foods -- such as cookies, crackers and other commercially baked goods -- made with these ingredients. Trans fat raises LDL cholesterol and lowers high-density lipoprotein (HDL), the "good" cholesterol.



Hydrolyzed: A protein obtained from various foods (like soybeans, corn or wheat), then broken down into amino acids by a chemical process called acid hydrolysis. Hydrolyzed plant or vegetable protein is used as a flavor enhancer in numerous processed foods like soups, chilis, sauces, stews and some meat products like frankfurters. Hydrolyzation of protein inevitably creates some (processed) free glutamic acid (MSG).



Manufacturers are acutely aware that many consumers would prefer not to have MSG in their food. Some manufacturers have responded by using "clean labels," i.e., labels that contain only ingredient names they think consumers will not recognize as containing MSG -- names such as "hydrolyzed soy protein." Others advertise "No MSG," "No MSG Added," or "No Added MSG," even though their products contain MSG

Soy lecithin is a mixture of fatty substances that are derived from the processing of soybeans. Lecithin is separated from soybean oil by the addition of water and centrifugation (rapid spinning) and purified for use as a food additive. Its chemical name is phosphatidylcholine, which identifies its major components of choline, phosphoric acid, glycerin, and fatty acids. Lecithin is used widely in foods as an emulsifier, stabilizer, and antioxidant.



Studies show most soy-allergic individual can safely eat products containing soy lecithin without experiencing any allergic reactions.



Although soyfoods are widely recognized for their nutritional qualities, interest in soyfoods has risen recently because scientists have discovered that a soy component called isoflavones appears to reduce the risk of cancer. More research needs to be done to determine exactly how isoflavones work, but it appears that as little as one serving of soyfoods a day may be enough to obtain the benefits of this anticancer phytochemical.



Traditional soy products such as tofu, tempeh, and soy milk are very high in protein. Tempeh has the highest percentage of protein of the traditional soy products providing approximately 22 grams of protein for each 4 ounce (113 gram) serving. Tofu provides approximately 9 grams of protein for a similar small serving size. The Recommended Dietary Allowance of protein for adult males (aged 25-50) is appoximately 63 grams and 50 grams for adult females (aged 25-50). Soy products can provide a significant portion of one's daily protein needs.



It is important to keep in mind, however, that the balance of amino acids (protein building blocks) in soy is not the same as meat. Because soy foods does not have an ideal balance of amino acids, some experts recommend taking in a little extra soy foods and/or combining soy products or legumes with a whole grain dish at meals where other protein (e.g., eggs, fish) is not eaten. The amino acids in whole grains combine well with amino acids in soy and legumes to make a more ideal balance of amino acids. If a person's diet is reasonably-balanced, however, there is usually no need to be concerned about getting enough protein.

Vegetarians and health enthusiasts have known for years that foods rich in soy protein offer a good alternative to meat, poultry, and other animal-based products. As consumers have pursued healthier lifestyles in recent years, consumption of soy foods has risen steadily, bolstered by scientific studies showing health benefits from these products. Last October, the Food and Drug Administration gave food manufacturers permission to put labels on products high in soy protein indicating that these foods may help lower heart disease risk.



As with health claims for oat bran and other foods before it, this health claim provides consumers with solid scientific information about the benefits of soy protein and helps them make informed choices to create a "heart healthy" diet. Health claims encourage food manufacturers to make more healthful products. With soy, food manufacturers have responded with a cornucopia of soy-based wares. (See "The Soy Health Claim.")



No sooner had FDA proposed the health claim regulation, however, than concerns arose about certain components in soy products, particularly isoflavones. Resulting questions have engulfed the regulation in controversy.



This came as no surprise to Elizabeth A. Yetley, Ph.D., lead scientist for nutrition at FDA's Center for Food Safety and Applied Nutrition . "Every dietary health claim that has ever been published has had controversy," she says, "even the relationship of saturated fat to a healthy diet."



While the controversy may seem confusing to the consumer giving it casual consideration, a careful review of the science behind the rule reveals a strict divide between what FDA allows as a health claim based on solid scientific research and related issues that go well beyond the approved statements about health benefits of soy protein.

Simply put, mono- and diglycerides are fats. They are made from oil,usually soybean, cottonseed, sunflower, or palm oil, act as emulsifiers (provide a consistent texture and prevent separation), and are used in most baked products to keep them from getting stale. In ice cream and other processed foods, including margarine, instant potatoes, and chewing gum, they serve as stabilizers, which give foods body and improve consistency.



Mono and diglycerides themselves do not contain gluten, but mono and diglycerides are almost always on lists of questionable foods for celiacs because of the possibility that wheat might be used with them as a carrier.



Under FDA regulations, a carrier used with mono and diglycerides in this manner would fall into the incidental additive category. Additives are considered incidental when they are present in insignificant amounts and have no technical or functional effect on the final food product. FDA regulations, which generally require that all ingredients of a food be listed on the label, do allow certain incidental additives to be left off the label.



However, recent concern about allergens has led the FDA to warn food manufacturers that it does not consider the eight most common food allergens (eggs, fish, milk, peanuts, shellfish, soy, tree nuts, and wheat) eligible for this labeling exemption. The FDA first clarified the exemption in 1996 in response to a growing number of reports of allergic reactions from foods that according to their label should have been allergen free. Now, the FDA has updated that clarification in a compliance policy guide for the food industry that says incidental additives containing common food allergens have never been considered eligible for the exemption. The Food Allergy Issues Alliance, a group of food trade associations and consumer interest groups, in May issued labeling guidelines that say incidental additives should be on the label. For celiacs this means that if wheat is used as a carrier for mono and diglycerides, it has to be declared on the label.



All this would seem to indicate that celiacs can remove mono and diglycerides from any suspicious or questionable food lists and still feel safe.

Sodium Benzoate

Used as a food preservative or antiseptic, sodium benzoate is a white crystalline powder chemically known as C7H5O2Na or E211. Although it is classified by the Federal Drug Administration as safe, sodium benzoate is a controversial additive. Sodium benzoate was previously used for centuries as a preservative to prevent the growth of microbial organisms in the food. In presence of Vitamin C (ascorbic acid) such as in jams, sodium benzoate can form the chemical benzene. Benzene is known to damage DNA, genetic material, which can lead to leukemia and other cancers. Since sodium benzoate works best in acidic environments, the consumption of sodium benzoate is a rising issue.

Potassium sorbate is the potassium salt of sorbic acid, and is much more soluble in water than the acid. Potassium sorbate will produce sorbic acid once it is dissolved in water and is the most widely used food preservative in the world. It is effective up to pH 6.5 but effectiveness increases as the pH decreases.

Flavor(s) Artificial

"The term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional."

The new labeling law effective in 2006, The Food Allergen Labeling and Consumer Protection Act (FALCPA), requires manufacturers to declare if one or more of the 8 major food allergens are contained in a natural flavoring. The top 8 major food allergens are defined as: milk, egg, fish, crustacean shellfish, tree nuts, wheat, peanuts and soybeans.

If you are managing food allergies other than the top 8 major food allergens, however, the new law will not be of assistance to you in identifying the sources in any natural flavoring stated on a label.

The FDA does not require companies to disclose ingredients of color or flavor additives so long as all the chemicals in them are considered by the agency to be GRAS ("generally recognized as safe") enabling companies to maintain secrecy of formulas. It also hides the fact that flavors often contain more ingredients than the foods to which they give taste.

A typical artificial strawberry flavor contains over 30 chemicals. According to manufacturer safety data sheets those chemicals cause eye irritation, corneal damage, eye burns, skin irritation, severe / permanent damage to digestive tract, gastrointestinal irritation, gastrointestinal tract burns, CNS depression, neurological effects, liver abnormalities, cardiac abnormalities, or other harm.

Natural flavor, according to the FDA, must be derived entirely from natural sources (herbs, spices, fruits, vegetables, beef, chicken, yeast, bark, roots, etc). Consumers prefer to see natural flavors on a label out of a belief they are more healthful.

Natural flavor is not necessarily more healthful or purer than an artificial flavor. Almond flavor when derived from natural sources may contain traces of hydrogen cyanide, a deadly poison. When derived by mixing oil of clove & amyl acetate, it does not. Natural flavors and artificial flavors are often manufactured at same chemical plants.

Flavor manufacturing may also involve biotechnology, using enzyme reactions, fermentation, & fungal and tissue cultures. Flavors created by these methods are considered natural flavors by the FDA.

In addition to flavor chemicals also think about genetic engineering of food, DNA or gene alteration, and medicines and hormones given to cows, cattle, hogs, and chickens. What affect does it have upon us? Some are suspected causes of cancer or other problems.

When a natural flavor or artificial flavor is added to a food or drink the resultant processed food is no longer natural & is potentially harmful.

A colorless, crystalline organic compound belonging to the family of carboxylic acids, present in practically all plants and in many animal tissues and fluids. It is one of a series of compounds involved in the physiological oxidation of fats, proteins, and carbohydrates to carbon dioxide and water.



First isolated from lemon juice by a Swedish chemist, Carl Wilhelm Scheele, in 1784, citric acid is manufactured by fermentation of cane sugar or molasses in the presence of a fungus, Aspergillus niger. It is used in confections and soft drinks (as a flavoring agent), in metal-cleaning compositions, and in improving the stability of foods and other organic substances (by suppressing the deleterious action of dissolved metal salts)."



Citrus fruits are notable for their fragrance, and most are juice-laden. They contain a high proportion of citric acid giving them their characteristic astringent odour and flavour. They are also good sources of vitamin C. In botanical terms, "The fruit of all Citrus trees, in which the true fruit is the peel, [is] made up of an outer layer, brightly colored and rich in glands, a spongey whitish mesocarp, and a membraneous endocarp surrounding the segments. The succulent parts we eat is only a secondary tissue developed as a filler"

Some brands of Citric Acid may be made from wheat, however this is very rare.

Vitamin A is very important for maintaining good vision. In fact, the first sign of a vitamin A deficiency is often night blindness. Vitamin A also contributes to the maintenance of healthy skin and mucous membranes that line the nose, sinuses, and mouth. Research has shown that this nutrient is necessary for proper immune system function, growth, bone formation, reproduction, and wound healing. Animal studies also suggest that it provides some protection from toxic chemicals such as dioxins. (Dioxins are released into the air from combustion processes such as commercial waste incineration and burning fuels like wood, coal or oil. These chemicals can also be found in cigarette smoke.)
