In food domain, should add only " homebred " " farmhouse " " feral " " organic " concept, the price and sales volume upgrade of loiter loiter loiter goes up. A lot of people feel these food taste sweet, nutrition safe.
Say earthy egg and foreign egg, their " argue " never had stopped. So in the supermarket, it is an egg likewise, "Earth, foreign egg " the price differs however a lot of. So, the egg comparing ocean with earthy true egg more nutrition?
Do not have blind faith in earthy egg nutrition again taller
A lot of consumer are right the impression of earthy egg, it is the breed of local earth chicken that point to is coming loose raise a condition to lay yield egg; And foreign egg points to commonly basket the egg below raised foreign chicken breed. So, what do earthy egg and foreign egg have to distinguish after all?
Earthy egg, the time that because be in hen abdomen,brews is a bit longer, inside adipose the egg that compares a farm with cholesterol content is a bit taller. But fowl-run uses special recipe feed, the vitamin of the egg and mineral some more. The paper that American scientist publishs points out, the egg with these two kinds of unripe chicken, there is substaintial distinction on nutrition.
Do not cross earthy chicken everywhere go for a walk, everybody does not run its mouth, investigator discovers, earthy egg contains 2 flower class status is higher than the egg of the farm. And 2 flower neither is produced artificially, do not have any utility again, be hard to biology degradation, rich in food chain collect, constitute serious menace to environment and health, already became the environmental problem that the whole world pays close attention to generally and communal and wholesome issue.
You perhaps do not know, home does not have national earthy egg occupation standard, so, the egg in the supermarket has many after all " earth " , everybody says to forbid. Be sure a lot of people have doubt here, is the food taste that makes for chicken of what earth egg, earth, aardvark sweeter? Because,this still basically is, their growth is periodic longer, what accumulate in the body is adipose much, and fragrance comes from adipose, common calls an animal oil.
The foreign egg that sells in the supermarket each is elite
And you are in understood a supermarket in " foreign egg " later, be afraid the meeting is right the egg has a brand-new knowledge. Above all, the breed of the color of egg carapace and chicken has very strong correlation, have nothing to do with the nutrient value of the egg. Student of college of Er of American health Nai expresses, the egg below the white chicken that ear leaf is white is white, the egg below the brown chicken of gules ear leaf is brown. But, generally speaking the chorion with deep color more not easy by crush.
The most crucial is, chicken lays and excreting what use is same a passageway -- cloacal chamber, did not touch on the egg that so the supermarket sells lose lose excrement and urine, still hold out actually unscientific, is this after all how accomplish?
In fowl-run, hen people live in such henhouse. 19 weeks of big hens can lay. Lay to promote a hen, imitate of solar lantern show the nature of 15 hours is smooth. The hen can take food 3 times everyday. Their food basically is the different cereal, soja that serves as protein, still have all sorts of vitamins and add to enhance the hardness of chorion egg carapace calcium. The hen is OK still from coop water water in device.
All designs of coop, it is for crop the biggest change. Live in the coop of such designs, every hen is average and annual can lay 300. Nevertheless, in the body of the hen " assemble " an egg, big essentials spends 24~26 hour. Because lay,be very big for the body to the hen use up, accordingly feral hen also issues 10~15 one year egg, and won't lay in the winter, industrialized egg chicken is the result that breeds artificially
See a hen lay postpartum egg next, where to go to. Coop bottom tilts, so the hen lays, this egg can boil automatically, roll a conveyer belt. This conveyer belt egg egg people take a bigger conveyer belt, carry them to the workshop that pack.
Generally speaking, of the hen can drop the conveyer belt below coop directly, won't big range pollutes an egg. But the thing always has in case. The egg that always has a few hens is not quite clean. Irrespective, can clean the egg that is infected with excrement and urine clean next.
Next, the machine can put the egg to plastic egg box above. Every egg is albumen face go up, yoke is gadarene. These eggs can be put to springhouse, carry egg grade center next in. The main job of this place is to give an egg to classification. Those who determine egg order and degree basically is 3 index: The hardness of chorion and whether to have place of crack, vitelline, and the size of the air chamber in the egg. Air chamber is bigger, grade is lower.
If the chorion of an egg does not have break, yoke is located in in the middle of, and air chamber is very small, it can achieve the class A of North America standard. Class A egg, after opening, look from flank stronger, ability is taken go selling in the supermarket.
Inferior egg can enter food processing factory, pharmaceutical factory, or cosmetic factory, production shampoo of what... a such automation line, can process 140 thousand eggs even hourly. Then, one sucks makings opportunity to suck the egg, put them to conveyer belt, take clean workshop. In clean workshop, can the machine uses brush, suds and face of chorion of alexipharmic fluid cleanness.
After passing dry operation of 5 seconds, the egg is about to undertake quality detects with grade. They should pass a bundle of strong light, the circumstance of such gallinaceous chorion does not have involuntary discharge of urine with respect to general view. The worker comes to the egg winkle of shatter by right of naked eye. Additional, above classification it is OK also like the head to photograph detect the circumstance of chorion.
Then, another machine can detect whether does egg interior have hematic spot. This is that blood dot that can appear sometimes in the egg that you see.
Respecting spot of this kind of blood, and the fleshy spot that can see occasionally, it is hen mom actually ovarian small hemal burst, tubal perhaps epithelial fall off form. The egg of spot having blood calls hematic spot the egg, occupy the 3-30% of all eggs. Company of breed of chicken of the egg that cross a state shows, the hematic spot of white carapace egg wants than the egg with deep color commonly little. Nevertheless, according to the standard of our country, hematic spot egg cannot be judged to be bright egg.
It is physics detects next the amused link of chorion hardness. Here, an acoustic sensor can beat chorion surface, the voice that uses chorion to give out can judge its hardness. This kind examines the technology of egg hardness is called mechanical knock to shake a technology. The egg that did not achieve class A can be labelled, be washed out next. Amount to the egg of mark, be said to weigh by electronic balance even, undertake farther classification according to weight. The egg is to use weight, is not size classification.
So the egg of the supermarket has have greatly small, but their weight is basic and identical. Next, the egg can be entered bale the workshop is packed and make a yard, go to a supermarket later like that, waiting to be bought by you.
So, if adopt national standard,produce national egg only, it is " the egg that amount to mark " , and its nutrient value, egg following earth is same. And respecting provision is safe, it is good that you guess the modern agriculture that is standard of dimensions large flow superintend, or scope is little, is the indigenous method agriculture that each shows special prowess better superintend?
It is our China or whole world no matter, farmland area is narrowing, grain crop is increasing, connect agriculture most the United States that develop, also dare do organic agriculture with the land of 1/200 only, if go to those who take land, do bad can " take land " .
