My grandma always gives me a big basket of eggs when I want to go back to work and live in the city after the holidays. However, these eggs were eaten up in a few weeks, and the eggs bought in the market later did not taste as fragrant as those in their hometown, and the color of the yolk was also very light, which was much worse in taste and taste.
Actually, most eggs are "feed eggs" now. The so-called "feed eggs" are eggs produced in farms. Hens are trapped in cages and eat feed every day. The eggs produced are large and the market price is relatively cheap. So when buying eggs, how to distinguish between "feed eggs" and "earth eggs"? Later, I asked a friend who is engaged in the wholesale business of eggs. He explained the difference between these two kinds of eggs in detail, and today I finally understood! What's the difference? I'll talk to you next.
1. Eggs are different in size
Many people think that the big ones are feed eggs and the small ones are native eggs, which is not completely correct. Generally speaking, however, soil eggs are indeed smaller than feed eggs. Because free-range chickens will eat some wild vegetables by themselves, or dig up the soil to find worms to eat, the daily food intake is insufficient, so the eggs laid are relatively small, and they don't lay eggs every day, and the egg production is relatively small.
Feed chickens are kept in farms, and they eat a certain amount of synthetic feed every day, so they eat enough and are full, so the feed eggs are relatively large.
Second, the color of egg yolk is different
This is easy to distinguish. If we pay a little attention, when frying eggs, sometimes we will see that some egg yolks are very light in color, that is, a faint light yellow, which is the feed egg. Because feed chickens eat few green vegetables in daily life, the carotenoid content in egg yolk is low, and the color of egg yolk is very light.
Free-range chickens eat more green vegetables, wild vegetables and weeds, so the carotenoids in the egg yolk are better and the color of the egg yolk is deeper. Therefore, earth eggs will taste more fragrant and delicious.
Third, the hardness of the egg shell
Free-range chickens usually eat some stones to help digestion, and the main component of the stones is calcium carbonate, and the component of the egg shell is calcium carbonate, so the shell of the egg will be thicker and harder. Sometimes when we knock it with one hand, the egg shell will still be intact, and it needs a little force to break it. However, feed chickens don't eat a certain amount of stones on weekdays, so the feed egg shell lacks enough calcium carbonate, so it is very thin and brittle. When you hit a dozen eggs with one hand, it will be broken at once.
When you sell eggs, you should try to buy as few feed eggs as possible, no matter how cheap they are. Although the price of local eggs is relatively higher, it is recommended that you buy local eggs for the health of your family. Today, the sharing of Bear is here.
