After an egg is born, we besides doubt it is gallinaceous hatch egg, still be the egg gave birth to chicken. Are you still thinking why can water washed egg deteriorate very quickly? Medicinal powder is yellow egg how to return a responsibility? What reason is the young black of surface of the yoke when the egg that boil? Why cannot have unripe egg egg white?
Why can water washed egg deteriorate very quickly?
When the egg is born, there is shape of a water-solubility glue to stick albumen outside chorion, make chorion surface lacklustre, submit frost form, it is microbial to preventing enter carbon dioxide is reached with the moisture inside the egg inside the egg excessive and outward evaporate is initiating protective action. Because this film is of water-solubility, because this is storing,want when the egg moistureproof, cannot bath or drench, can deteriorate very quickly otherwise corrupt. And do not want surface of choose and buy not to have frost account other people when egg of choose and buy, and glossy shines not clean egg, such egg is not new already, the surface outside should choosing shows frost shape, lacklustre and clean egg edible.
Do this come loose how is yellow egg to return a responsibility?
Yoke is secure the center in the egg by two chalaza, the extension as deposit time and external temperature are elevatory, chalaza taper off, disappear finally, yoke ends from which removed, gradually rise sticks housing. Accordingly, medicinal powder yellow egg also is Biedermeier.
What material is the young black of surface of the yoke when the egg that boil?
The protein of the egg is rich, contain a lot ofacid of half Guang ammonia among them, heat excessive meeting makes acid of half Guang ammonia decomposes generation vulcanization hydrogen partly, with the iron in yoke union can form vulcanization iron of black. The young black material of surface of the yoke in the egg that boil originates this.
Why cannot have unripe egg egg white?
In unripe egg egg white, contain antibiosis content element albumen and fight trypsin. Protein of antibiosis content vegetable can be united in wedlock inside alvine path with biology element, affect the absorption of biology element, return the symptom that can cause biology element to lack; Fight trypsin to be able to restrain the vigor with enzymatic albumen, cloggy albumen is digested absorb, reason cannot be born feed clear.
Store egg moment must is end up put?
Yes. Because vitelline proportion is less than albumen, the big head of choice general egg up, small head over heels, erect deposit, although albumen becomes rare, also won't happen very quickly rely on Huang He to stick leather phenomenon. Can prevent already so microbial invade yoke, also be helpful for assuring the quality of egg products.
How long does the egg boil mouthfeel best?
Have vitelline beauty only small make up want to say, cold water coddle 8 minutes of mouthfeel are best.
Put the egg into cold water boiler directly, firing next boil. When 8 minutes, egg white is already caky, yoke also slightly caky, color is golden. Right now, fight nutrient material to be destroyed, also can be salmonella control inside safe limits, and nutrient reservation is relatively complete, can say " perfect " . The mouthfeel of hot water coddle and cold water do not have difference, but hot water coddle splits case more easily, egg fluid flies easily.
