Included for each food is its weight in grams, its calories, and (also in grams,) the amount of protein, carbohydrates, dietary fiber, fat, and saturated fat. [1] As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels.
In general, the fresher an egg before boiling, the more difficult it is to separate the shell cleanly from the egg white. [22] As a fresh egg ages, it gradually loses both moisture and carbon dioxide through pores in the shell; as a consequence, the contents of the egg shrink, it loses protein, and the pH of the albumen becomes more basic.

A 1991 assay for the Journal of Food Science detected substantial avidin activity in cooked egg white: "mean residual avidin activity in fried, poached and boiled (2 min) egg white was 33, 71 and 40% of the activity in raw egg white." The assay surmised that cooking times were not sufficient to adequately heat all cold spot areas within the egg ...
The albumen (egg white) contains protein, but little or no fat, and may be used in cooking separately from the yolk. The proteins in egg white allow it to form foams and aerated dishes. Egg whites may be aerated or whipped to a light, fluffy consistency, and often are used in desserts such as meringues and mousse.
Some protein powders also use egg whites as a primary source of protein. The albumen from egg white was used as a binding agent in early photography during an 1855-90 period; such prints were called albumen prints. In the 1750s, egg whites were believed to prevent swelling, and were used for that purpose. To help soothe areas of skin that were ...
Fill a medium saucepan with water (about 2 inches from the top) and place on the stove. Turn the heat to medium-high and let the water come to a boil.
Normally egg protein is assumed to be the most readily utilizable protein and given a BV of 100. For example: Two tests of BV are carried out on the same person; one with the test protein source and one with a reference protein (egg protein). relative BV = ( BV (test) / BV (egg)) * 100. Where: BV (test) = percentage BV of the test diet for that ...
Ovalbumin (abbreviated OVA [1]) is the main protein found in egg white, making up approximately 55% of the total protein. [2] Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily, but unlike most serpins it is not a serine protease inhibitor. [3]
