The egg is one material compact nutrient cropped by bird, the egg can benefit for requirement various. some kind of egg is turn in the market, but just kind of egg certain it can be trade and consumption by human there are chicken egg, duck egg, quail egg and goose egg. It fact, chicken egg the most popular in consumen area.
The egg is a food good for child growing and need protein in majority, the egg also so good to consumption for pregnant mother, give suck mother and people sick.
The egg is constituted source of protein so good beside milk, the egg is rich in amino sours, carbohydrate, fat, vitamin, and mineral. Egg protein is a protein high quality and digested, in the egg much of protein be found at egg yolk, as many 16.5% while in white egg as many 10.9%, in the other flank close all the fat be found in the egg yolk, it is reached 32%, while in the white egg be found fat in a little sum, in the order word the white egg in protein well, white egg yolk is fat well.
The egg consist to skin egg, kutikula, skin white egg (albumen), egg yolk (yolk), germ sport and air pocket, structure of the egg can see in the picture bellow:

Skin Egg
Skin of egg is part of wrapping layer by cuticle in the outsides part. Skin egg has thick surface, stiff and hard who has function as egg protected from damage, there are two anat or membrane is coat kerabang membrane of skin consist two lagen, there are; outside and inside membrane.
Outside membrane more thick then inside membrane, the thick skin membrane every kind of egg be different, there are chicken egg 0.01 mm until 0.02 mm, duck egg and goose egg has skin thickness around 0.3 until 0.5 mm, while quail egg has skin thickness 0.19 mm.
Skin membrane function to restrain join the microorganism from outside and to protect the albumen (white egg), kalaza function to placing on a solid footing egg yolk position. Kalaza layer also constitute o divider between albumin and egg yolk, the component of composer albumen consist on the wather, foods, organic and anorganic material, now the composer component egg albumen can be set out in the table below.
Egg Yolk
The egg yolk is part of egg have the shape of circle, yellow color, and located in middle place, egg yolk of chicken much be pregnant lute in zat.
The egg yolk be pregnant a weather, protein, fat, and some mineral egg yolk border with white egg and wrapped by some layer it’s called the vitelin membrane, this membrane arranged of protein is called a keratin, egg yolk located in to egg central and elastic quality, yellow color at egg yolk be caused of sentrofil pregnant is from chickens food, the other pigment much from in is pigment karotenoid.
White Egg (Albumin)
The albumin or familiar names white egg a little greenness color, albumin have high weather pregnant, elastic quality and protect an egg from a shake.
White egg shape agency framer good foam, this matter resulted by interaction between constituent protein various. Requirement of base protein for shape agency farmer a god it is ability with hery in the interface air-weather as long as shaking and compose viskoelastis layer by interaction intermolecular, shape is dispense colloid from gas faze in liquid faze, it can be shape when the egg shacked. Mechanism formed egg shape is opened bounds in protein molecule until he chain of protein been more long next the air is enter between molecules opened it chain and endured until happen the promoter volume. The shaking white egg can be influence the volume of white shape. More little get caught the air, the formed of foam more soft while more much the air get caught, the foam is formed more stiff and the characteristic current.
B. The Kinds of Egg

An egg of chicken, contain around 12.8 gram protein, percentage uterus of protein in the egg of chicken to a ground 12.7%. Certainly this point out uterus protein in an egg of chicken more high than a glass of milk. The protein in 100 ml just 3% high and it low of protein in a food be hanging uterus of water more from an egg.
