The shell of the feed egg is slightly thicker and darker, and the yolk is slightly light yellow, which is easy to stir when stirred, and the liquid is very thin and light yellow in color. The eggs are slightly smaller, the shell is slightly thinner, the color is light, there is a thin white film, the yolk inside is slightly smaller, golden yellow, there is a strong viscous feeling when stirred, and the liquid color is dark yellow. Although we all know that the nutritional content of native eggs is much higher than that of feed eggs, how do we choose native eggs when we go to the supermarket or vegetable market in life?
And how to distinguish the difference between native eggs and feed eggs, let's teach you how to distinguish.
Tools Raw materials.
Eggs, plates, chopsticks.

1 3 Step by Step Reading.
First, look at the appearance. Judging by the appearance of the eggs, there seems to be no difference between the two. But on closer inspection, there is a difference. The eggs are slightly smaller, the shell is slightly thinner, and the color is lighter, and the fresher ones have a thin white film. Whereas, the shell of the feed egg is slightly thicker and darker.
Second, look at the egg yolk: only from the appearance, may not be able to see the layman's doorway, rural people have a good way to identify, you can buy the egg to open the shell, if the yolk is slightly smaller, the golden is the native egg; If the yolk is slightly larger and light yellow, it is a feed egg.
3. Look at the ease of stirring. Feed eggs can be easily stirred when stirred, and the liquid of the eggs is very thin and light yellow in color. When the eggs are stirred, they have a strong viscous feeling, and the liquid color is dark yellow.
Precautions. If the yolk is slightly larger and light yellow, it is a feed egg.

It has higher nutritional value and better antioxidant properties than feed eggs.

There is no difference between Lingxiang Valley Ganoderma lucidum native eggs and native eggs, both of which use exaggerated ways to deceive consumers, and the nutrition of eggs is the same, but there are slight differences in content.
Eggs, also known as chicken eggs and chickens, are eggs laid by hens. It has a hard shell on the outside and an air cell, egg white and yolk on the inside. Rich in cholesterol and rich in nutrients.
An egg weighs about 50 grams and contains 7-8 grams of protein and 5-6 grams of fat. The amino acid ratio of egg protein is very suitable for the physiological needs of the human body, easy to be absorbed by the body, the utilization rate is as high as 98%, the nutritional value is very high, and it is one of the foods commonly eaten by humans. Contains high protein.
Eggs are good for high-quality protein, B vitamins**, and also provide a certain amount of fat, vitamin A, and minerals. A medium-sized egg provides around 6 grams of high-quality protein, the highest protein of any food.
The cooking method of eggs is nothing more than frying, scrambling, steaming, boiling, because the eggs themselves contain high fat, and then cooked by oil, not only greatly reduce the nutritional value of eggs, but also make people increase the intake of fat in the process of eating, so it is not recommended to eat too many fried and fried eggs.
Some people think that soft-boiled eggs have high nutritional value, but this is actually very unscientific. From a sterilization point of view, cooking eggs must reach a core temperature of 70 to 80 degrees Celsius to kill Salmonella, and when the yolk sets, the temperature is approaching. Therefore, it is best to start the pot when the yolk has just set, and it is not recommended to eat soft-boiled eggs.

1. From a scientific point of view, there is not much difference between the eggs laid by free-range chickens and caged chickens from the protein content, amino acid content, and lecithin.
2. Laying hens in chicken places eat scientifically formulated feed, which is very nutritious, but it is impossible to be as rich in "taste" as feed in nature. It is well known that food affects the taste of animals, just as people who eat meat have different tastes from those who eat vegetarian food, and people who eat beef and mutton have different tastes from those who eat fish. It's the same with eggs:
Free-range chickens can eat natural "flavor foods" such as grass, insects, grains and grass seeds, and the flavor substances produced in eggs are naturally rich. Chickens raised on chicken farms eat a mixture of feed all year round, and the natural flavor is monotonous.
3. Let's talk about the color of the egg yolk. Free-range chickens often eat grass and leaves, and green leaves are rich in carotenoids, which accumulate in the yolk and dye the yolk a beautiful orange-red color. Chickens that eat feed don't have a chance to eat grass, so the yolk only has the light yellow color of riboflavin.
However, the feeding method cannot be judged by the color of the egg yolk alone, because at present, some feed additives such as "plus Lisu" have been developed at home and abroad, and the color of the egg yolk will become very beautiful when they are added to the feed. Of course, such additives are safe and harmless.
4. Nutritional studies have found that there is no significant difference in protein, carbohydrates, calcium, iron and other components between the eggs laid by free-range chickens and fed chickens. Due to the abundance of vitamins added to chicken feed, eggs produced tend to contain higher levels of B vitamins and vitamin A than eggs produced by free-range chickens. However, there are significant differences in fat content, vitamin E content, and long-chain polyunsaturated fatty acid content, and the eggs produced by free-range chickens are higher than those produced by feed chickens.
Therefore, it can be said that their nutritional value has its own merits, and it is difficult to say which is better or worse.
-
There is a difference, the difference is that the local chickens that produce native eggs do not eat the special formula feed for Ganoderma lucidum spore powder.
-
It is indeed free-range, because he has a lot of chickens in a mountain in Linquan Guling.

Before the field trip, no one can guarantee that the egg will be free-range.
-
Yunquan jade Ganoderma lucidum eggs, are you sure they are free-range? Even if you want to buy him, you should believe him, he said that it is free-range, then it must be free-range.
-
Now someone fences off a mountain and uses it exclusively to feed the chickens, which can be regarded as free-range.
-
Yuan Quan, Jia Ling is a native egg, are you sure that it is free-range? It should be free-range. Because that's what it says on it.

-
Some time ago, there was a news that it was a native egg, but it was found out that the veterinary antibiotics were exceeded.
-
It can only be said that it is indeed free-range, because they say that the free-range is the free-range itself, which is more expensive, so it is basically free-range, so the quality is indeed the best.
