There is no significant difference between feed egg nutrition and soil egg nutrition, and there is no significant difference in amino acid content between them. The nutritional value of native eggs is not only higher than that of feed eggs, but also because of the free-range environment of native eggs, they are more likely to come into contact with chemicals such as pesticides and fertilizers, and the possibility of being contaminated by agricultural chemicals is higher than that of eggs produced in chicken places.

Centralized feeding of chickens in chicken farms, even though there will be many problems in feed, can be found. It is difficult to know where the earth eggs come from. Therefore, from the perspective of food safety, the risk of earth eggs is higher.

Method for selecting eggs:

1, egg inspection method by light: if the egg is fresh, you can see that the egg will be reddish and translucent, the outline of the yolk is clear, and the protein and yolk are obviously separated. Otherwise, the egg will be stained and dark and opaque.

2, eggshell observation method: generally fresh eggs, eggshells will be attached with a layer of micro-frost, the color of eggshells is bright and smooth, on the contrary, the color of eggshells is darker, and spots will appear greasy.

3, gently shake the egg method: the egg is held in your hand and gently shaken. If the egg has no sound, it means fresh. On the contrary, the egg has a water-like vibration sound, which means it is not fresh. This is the simplest and easy to operate, and the best test method for buying eggs on weekdays.

4. Cold water test method: put the egg into the water. If the egg is flat, it means fresh. If the egg tilts, it means that it has been stored for about 5 days. If the egg stands directly in the water, it means that the egg may have deteriorated.
