What is the difference between eggs and native eggs, and what is the difference between ordinary egg

Ordinary eggs are slightly larger, and native eggs are slightly smaller; The yolk of native eggs is red and high in fat; Ordinary eggs have a yellowish yolk and are low in fat. In terms of nutritional value, the protein content of ordinary eggs is high, and the fat content of native eggs is slightly higher, and the nutritional value is about the same.

It is said that native eggs are highly nutritious, but there are many fakes.

Studies have proved that the nutritional content of native eggs and ordinary eggs is not much different, and if you really want to strictly distinguish them, you can only say that they have their own advantages. Ordinary eggs are richer in vitamin B and vitamin A than native eggs. Native eggs are high in vitamin E and long-chain polyunsaturated fatty acids.

Therefore, we cannot exaggerate the nutrition of native eggs from the aspect of nutritional value and think that ordinary eggs are not nutritious.

The public thinks that local chickens grow in a natural environment and eat natural food, and the quality of eggs produced will naturally be better. Chickens raised on chicken farms eat feed, so their nutritional value is not high. The taste of native eggs is more fragrant than ordinary eggs, and native eggs have a good taste and fragrant taste, while ordinary eggs feel that they are not nutritious when they have no taste in the past.

First of all, chicken farms raise the eggs laid by laying hens. If the farm is raised, the feed is scientifically proportioned, and the nutritional value is definitely no problem. Native eggs have a better taste because of their higher fat and cholesterol content, while ordinary eggs have a coarser taste because of their higher moisture content.

However, because of the high fat content of native eggs, they are not suitable for the elderly.

The yolk of a better native egg is very tightly combined, and it will not break easily when poked with your fingers or held by hand, and the yolk membrane is not easy to break, and the yolk inside is also very thick. The egg white of the native egg is thick, and compared with ordinary eggs, it can be observed that the egg white binding degree is much higher, and the albumin outflow is much less. After the eggs are boiled in water, the yolk and egg white are very distinct, and the color of almost the entire egg yolk is relatively uniform and consistent, and there is no obvious color layering.

The egg whites are also the same color, and the egg yolk and protein are relatively firm, and there will be no gray or black color.

The nutrition of eggs depends on the feed and environment, there are good quality farmed eggs, high-grade can be eaten raw; There are also farmed eggs that only seek production, which are yellow and thin, and the taste is light. The nutritional content of the "foreign eggs" produced by the regular is up to standard. If you have to compare the cheapest low-grade farmed eggs with "native eggs", it is called hooliganism.

This is "scarce is expensive", although expensive is not necessarily right, but expensive is naturally (easy) for everyone to think that it is (nutritional) value high. The same is true for native eggs, in fact, frankly speaking, native eggs and ordinary eggs are eggs, and the nutritional value can of course have their own merits, but it really can't be said that the nutritional value of that kind of egg is much higher than that kind of egg.

Due to the different ways of feeding, local chickens may get more comprehensive nutrition than chickens in ordinary chicken farms, from the nutritional content of eggs, local eggs in protein, carbohydrates, cholesterol, calcium, zinc, copper, manganese are higher than ordinary eggs, which is related to the proportion of egg yolks; However, the fat, niacin, and selenium in native eggs are lower than those in ordinary eggs; The other nutrients are not much different.

Ordinary eggs now generally refer to the feed eggs raised on a large scale in chicken farms, and native eggs now generally refer to the eggs laid by free-range chickens raised by families, and the taste may be different, but there is not much difference in nutrition.

Native eggs are delicious, and there is no difference in nutrition.

1. The color of native eggs and ordinary eggs is different, because native chickens are stocked under natural conditions, they absorb natural sunlight, while ordinary eggs are fed under feed conditions, and they absorb light irradiation;

2. The yolk of the egg is different from the yolk of the ordinary egg, the color of the yolk of the egg is slightly darker, the yolk of the ordinary egg is slightly yellow, the size of the egg is different, the yolk of the egg is slightly smaller, and the yolk of the ordinary egg is slightly larger;

3. The egg white of native eggs is different from that of ordinary eggs, and the egg white stratification of native eggs is more obvious, while the egg white stratification of ordinary eggs is very thin and not obvious;

4. Fresh eggs have a layer of film that is more obvious, which is natural to touch with your hands, while the film of ordinary eggs contains macros that are not obvious;

5. The thickness of the eggshell is different, the eggshell of the native egg is thicker, while the eggshell of the ordinary egg is thinner.

Yields are different: Ordinary hens can produce more than 300 fresh eggs every year, an average of about one a day, and the egg production rate of local chickens is only 1 3 of ordinary chickens, that is, an average of 3 sweet eggs have an egg, according to the law of scarcity is expensive, the ** of native eggs is naturally more expensive than ordinary fresh eggs.

The shape is not the same:Ordinary fresh eggs are symmetrical in size and the color of the eggshell is uniform, they are all light brown, and the overall size is larger than the native eggs, 5-6 eggs are a catty, and the local eggs are small, the eggshell color is pink or dark brown, and there are about 10 eggs in a catty.

The value of eggs.

Brain puzzle: First of all, we eat eggs can help promote brain health, mainly in the yolk of eggs lecithin is very rich, and after such substances are digested by the human body, at this time can effectively release choline, and choline can help us enhance memory and protect our brain health.

Protect the liver: The protein in the egg is very rich, and protein is a substance that everyone is more familiar with, in fact, protein can play a repair role in liver tissue damage, which is helpful for everyone to promote liver health, and can also effectively promote the regeneration of liver cells, which is meaningful for the prevention of liver diseases, and can also promote the improvement of metabolic function and immune function.

The difference between native eggs and ordinary eggs is that the hardness of the eggshell is different, the color of the yolk is different, the taste is different, the size is different, and the flexibility of the egg white after cooking is different.

1. The hardness of eggshells is different.

The volume of the eggs is relatively small, and the color of the eggshell is also relatively light, the fresher eggs have a thin membrane, its eggshell hardness is relatively high, and the ordinary eggs are more fragile, easy to break, and the shell color of ordinary eggs is also darker.

2. The color of the egg yolk is different.

If you open the egg, it is easier to compare the difference between the native egg and the feed egg, the color of the egg yolk after the egg is peeled is more golden, the color looks very dazzling, and the size of the egg yolk is relatively full, it is not easy to spread Wu Pei, the water in the egg yolk is less, more compact, and the color of the feed egg looks a little light, the yellow is mixed with a lot of white, this is because the feed egg has more moisture, after the egg is opened, the yolk will be softer, easy to collapse, Such a yellow color must be fodder eggs.

3. The taste is different.

The taste of authentic eggs is very fragrant, and even if it is a boiled egg, it is very good.

4. The size is different.

The volume of native eggs is small, but the volume of egg yolk is not small, and the egg water content of ordinary eggs is more.

5. Protein flexibility after cooking.

After they are all cooked, the eggs are placed in the hand and pinched, and the egg whites will not crack, while ordinary eggs are different, and they are easy to break.

<> appearance is different: the individual differences of native eggs are large, generally the same batch (more than 10) eggs have obvious color differences, while ordinary eggs are larger, individual differences are very small, and the shell color is darker. Egg yolks are different:

The yolk of native eggs is generally golden yellow, while the yolk of ordinary eggs is generally light yellow. Different taste: Native eggs do not contain any synthetic antibiotics, hormones and pigments, and the egg whites are thicker and more fragrant than ordinary eggs.

1. The difference between native eggs and ordinary eggs

1. The appearance is different.

When a batch (more than 10) eggs have obvious color differences, it can be basically judged to be native eggs; Whereas, the body size of ordinary eggs is comparatively larger, the individual differences are small, and the shell color is darker.

2. The eggshell is different.

The eggshell of native eggs contains a large amount of calcium, and the eggshell is thick and hard; The shell of a regular egg is thinner and brittle.

3. The egg yolk is different.

The yolk of native eggs is generally golden yellow; The yolk of a regular egg is generally light yellow in color.

4. The taste is different.

Native eggs do not contain any synthetic antibiotics, hormones and pigments, and the egg whites are thicker and more fragrant than ordinary eggs.

2. Precautions for egg storage

1. When the eggs are stored in the refrigerator, the big head should be up, and the small head should be down, so that the egg yolk will float up and stick under the air chamber, which is conducive to ensuring the quality of the egg and preventing microorganisms from invading the egg yolk.

2. Eggs can not be stored horizontally, the specific gravity of the egg yolk is smaller than the egg white, and the egg is placed vertically, the egg yolk will float, close to the eggshell, and become a sticky shell egg, so it is not suitable to be stored horizontally.

3. When there is no refrigeration condition, try to use clean paper or cloth to make egg-shaped holes, so that each egg can have an independent storage space, avoid direct exposure to the air, reduce the invasion of bacteria and microorganisms, and prolong the storage time of eggs.

4. If the eggs you just bought back have dirt on the surface, do not wash them with water, otherwise the eggs are easy to spoil, and the fresh eggs taken out of the refrigerator should be eaten as soon as possible, and cannot be stored for a long time or refrigerated again.

The difference between native eggs and ordinary eggs:

1. The shape color is different.

Compared to regular eggs, real eggs are smaller, generally between 42-53 grams. The size and color of the eggs in the soil shed are different, unlike the ordinary eggs sold in the market, which are large and the color is so uniform.

2. The taste is different.

If the taste ratio of native eggs is poor, it is more fragrant and tender, and there is no eggy smell; The taste of ordinary eggs is not so good, and some brands of eggs have darker yolks after they are cooked, and the taste is very firm, and even some hard, which is not normal.

3. There is a big difference.

The egg laying rate of ordinary cage chickens can reach 95%, and the annual egg production is more than 300. The egg laying rate of local chickens is only about 30%, that is to say, each local chicken has to accumulate an average of 3-4 days of nutrition to lay a small egg, and the number of eggs laid per year is difficult to exceed 100. The cost of native eggs is more than double that of ordinary eggs, and the market price is almost half more expensive than ordinary eggs.

Knowledge of native eggs and ordinary 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.

The same is true for eggs: free-range chickens can eat natural flavors such as grass, insects, grains and grass seeds, and the flavor substances produced in eggs are naturally richer. 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, it is not possible to judge the feeding method based on the color of the egg yolk alone, because the liquid has been developed at home and abroad some feed additives such as garisol, and the color of the egg yolk will become very beautiful when they are added to the feed, of course, this kind of additives are safe and harmless.
