How to distinguish between colored eggs in the market and farmyard eggs

There are three main ways to distinguish them:

1.Native eggs come in different sizes. Due to the nutritional imbalance caused by the way of raising and the food raised, the eggs laid are of different sizes and egg shells.

The colors are also different. Due to the uniform and regular way of raising and food, factory-raised chickens produce eggs of uniform size and the same color of eggshells. If you buy eggs in the supermarket and find that the eggs are uniform in size and the same color as the eggshell, they are generally factory farmed, and they are not authentic "native eggs" at all.

The "soil" on the label is not necessarily really "soil".

2.The yolk of the native egg is darker, and the yolk of the pigmented egg is reddish. Because local chickens eat more green food, the carotenoids in egg yolks.

and vitamin B2 content, so the yolk is larger and darker than the pigmented egg. The yolk of native eggs is plump, golden yellow, and has a high relative fat content. In the feeding of pigmented eggs, pigment is added to the feed, and the yolk of the eggs laid is reddish.

This is also the reason why many people pretend to be native eggs.

3.The sale of native eggs is higher. The local chickens of the farmers are all raised through their own "free-range" breeding, and the number is limited, resulting in a high cost of raising local chickens and a small number of local eggs.

Pigmented eggs on the market are factory farmed. Large-scale breeding, centralized breeding. Therefore, the yield of pigmented eggs is large and the cost is not high.

Therefore, in the market, the ** of native eggs must be more expensive than those of pigmented eggs. If you encounter the sales method of egg ** in the supermarket, which is very cheap, you must pay attention to the fact that it is likely to be colored eggs.

To sum up, the ways to distinguish between pigmented eggs on the market and farmhouse eggs are:1The size of the eggs varies, and the size of the pigmented eggs is uniform.

2.The yolk of native eggs is darker and yellowish, and the yolk of pigmented eggs is reddish 3The sale of native eggs** is more expensive than pigmented eggs.

Combined with the above three identification methods, native eggs and pigmented eggs can still be clearly distinguished.

The size of the eggs is different, the shape is also different, the color of the egg yolk will be darker, and the egg will be sold higher. But pigmented eggs may be uniform in size, and the yolk will not be particularly dark, and it is also particularly cheap.

The real native eggs are smaller, the yolk is yellower, and the eggs laid by the laying hens in the early stage of egg laying are generally smaller, and some egg manufacturers will choose such eggs, and then pass off as native eggs. In order to make this egg more like a native egg, some manufacturers will also communicate with chicken farms in advance and ask them to add some practical pigments to the feed.

It can be judged according to the color, according to the size, according to the specific **, according to the place of origin, and according to the number of goods.

It is said that this native egg is highly nutritious, but how to distinguish the real from the fake? In fact, there are many ways to distinguish the real from the fake of local eggs. Many of these methods are very simple. Today I am going to share with you a few methods. I won't be fooled in the future.

Usually, when we buy home-grown eggs, many vendors will sell them shoddy, because home-grown eggs are basically sold by themselves, usually selling for two yuan each. But like ordinary eggs, they are per catty, so there will be huge business opportunities for low-quality eggs. We also have many ways to distinguish real eggs from fake eggs.

First of all, which can be seen from the appearance of the egg. Judging by the appearance of the eggs, local eggs are small in size, thin in shell, and light in color. For example, some feed eggs are what we call ordinary eggs in Chama Town.

It has a thick shell and a dark color. You can tell from this comparison.

The second way is to look at the egg yolk。Let's start by beating the eggs in a bowl. Once opened, we can compare the egg yolks.

If the yolk is small and golden brown, it is a natural egg. If the yolk is relatively large and lighter in color, it means that it is a feed egg.

The third method is to identify with a toothpick。We can beat the eggs in a bowl and stick a toothpick directly into the yolk. When we insert some eggs, they will slowly slide to the side and tilt straight away.

But if it's like a natural egg, it won't move after inserting a toothpick.

The fourth method is to break the eggs. Usually, when we beat the eggs, if we find that the eggs are easy to beat and very thin, stir them a few times, and the yolk will fall apart directly. This indicates that it is a common feed egg.

If it were like some natural eggs, it wouldn't be so easy to open. The color is also yellow. The whole egg wash and yolk are also very sticky.

It's not easy to break up when playing.

The above is a little bit of how to distinguish local eggs that I would like to share with you today. In particular, sticking a toothpick on an egg does make a big difference.

I think the eggs are relatively large, and they are also darker, and the eggs are lighter in color and smaller.

Depending on the size of the egg and the color of the yolk, the eggs are small and the yolk is dark orange.

I think it can be distinguished by appearance, color, size, quality and nutritional value.

Eggs in the market are different in color. The cause of eggshell TEM discoloration is the presence of complex pigments in the eggshell. Various pigments are deposited in the eggshell in different proportions, forming a different color from the eggshell, from the perspective of the nutrients contained in foreign eggs and native eggs, foreign eggs are better, the reason is that foreign eggs use special egg layers and artificial scientific food, and have a more balanced diet.

In addition, the content of vitamins, iron, calcium, magnesium and other minerals in foreign eggs is greater than that of native eggs, and the content of fat and cholesterol is lower than that of native eggs.

The color of the eggshell has a certain relationship with nutrition, but it is not the main determining factor, and the color of the eggshell mainly depends on the variety. Different breeds lay eggs with different colors. Now there are layers of green casca, most of the eggs laid are green casca, people who often buy eggs know that eggs have many colors, mainly brown casca, pink casca, white casca and green casca, in the past, brown casca eggs were the main ones in the market, occupying more than 60% of the market share.

But in recent years, the number of eggs produced by roses has increased rapidly. At present, the market share of DOS is basically the same, accounting for more than 40% respectively, the color of the eggshell is mainly determined by the genetics of the chicken, which has nothing to do with the nutrition of the chicken and the nutrients contained in the egg, the color of the egg is related to the genetics of the chicken, and the darkest chicken is because these chickens can produce more egg porphyrins.

The eggshell is mainly composed of calcium carbonate, which is naturally white. Many birds cover their eggs with a pigment to help them identify their own eggs or disguise their own eggs as other eggs. In conclusion, the color of eggshells is usually from white to brown.

The color of the eggshell is determined by the pigment of the protoporphyrin in the eggshell. The amount of this pigment varies depending on the egg breed and has little to do with the nutritional value of the egg itself.

Adding a substance called eggshell porphyrin to chicken feed, the appearance of the eggshell may turn red, this substance has no effect on the internal composition of the egg, the color of the eggshell is related to the food you eat. For example, foods that contain more corn and red carotene in the feed will deposit some of this pigment, while stones and eggshells will be darker.

The nutritional value is about the same, in fact, there is no difference in the nutritional value of native eggs and ordinary eggs.

The different colors of eggs on the market have different nutritional values and are not the same. Among them, powdered eggs have the lowest **. And domestic eggs have the highest nutritional value.

Different colors of eggs on the market have the same nutritional value, but there may be some differences in taste.

Eggs are rich in nutrients and are a very important ingredient both as a staple food and in cooking. But now there are a variety of hormone feed eggs and artificial eggs on the market.

The appearance of the epidemic has made people feel panicked, so most customers have turned their attention to healthy local eggs.

So, how to distinguish native eggs from ordinary eggs in appearance? <>

First of all, the color of native eggs is lighter than that of ordinary eggs. The biggest difference between native eggs and ordinary eggs is the difference in appearance, which can be seen from the color of the eggshell, the color of native eggs is hemp white, while ordinary eggs are a little orange-yellow. If you can make the egg shell.

When you open it, you can find that the yolk of the native egg is much more yellow than that of ordinary eggs, the former is orange, and the latter is more yellow. <>

Secondly, ordinary eggs are larger than native eggs. The volume of the two is clear at a glance, and the difference in size is very obvious. Moreover, the individual differences of native eggs are relatively large, if you find that the color difference in a dozen eggs is more obvious, the color level contrast.

The higher it is, you can probably judge that it is a native egg. The individual differences of ordinary eggs are small, and the color difference between eggs is not obvious, if the body shape and color of a row of eggs are very uniform, it can be roughly judged as ordinary eggs.

Finally, the shell of a regular egg is not as hard as that of a native egg. The reason why native eggs are more popular is because the calcium and protein content in them is beyond the reach of ordinary eggs. As long as customers gently shake it with their hands, they can feel that ordinary eggs are much more fragile than native eggs.

The shell of a native egg is not only thick, but also hard. <>

If you still can't judge from the appearance, you can shake it to listen to the sound of the egg, because the native egg is rich in nutrients, so the egg white is denser. If it is an artificial egg or an ordinary egg, the sound of the egg white will sound sparse, however, this way of distinguishing is not very obvious, and it requires a sensitive hearing person to recognize.

The color of the eggs is generally relatively dark, and the size can also be basically distinguished, the eggs are uniform, the ordinary eggs are larger, and the skin of the eggs has a little dirty feeling.

From the appearance of the eggs, the eggs are slightly smaller, the shell is slightly thinner, the color is light, and the fresher ones have a thin white film. The shell of the foreign egg is slightly thicker and darker.

The size of native eggs is relatively small, the color of the egg skin is relatively yellow, and the egg shell is particularly thick, while the size of ordinary eggs is very large, and the egg skin is relatively brittle and easy to break.

There is a difference in the nutritional value of native eggs and ordinary eggs.

The main nutrients of eggs are food, native eggs are eggs laid by hens farmed in the wild, due to the fact that there are more grasses and vegetables in the food, but the protein intake is insufficient, therefore, the content of carotene and vitamin B2 in this egg is higher, the yolk is large and dark, and the total protein content is lower, resulting in a smaller egg as a whole.

The difference between native eggs and ordinary eggs.

The size is different. Native eggs: The feeding process of native eggs is relatively simple, almost no feed is given to the hens, and the chickens mainly rely on themselves to catch insects in the wild and supplement protein, so the native eggs are generally relatively small.

Ordinary eggs: Ordinary eggs are directly fed with feed, and there are semi-wild fed, all of which have eaten feed, and the nutritional supplement of the hens is very sufficient, therefore, the eggs are relatively large.

The color of the egg yolk is different.

Ordinary eggs: Ordinary eggs are mainly fed as food, and the vegetables and grasses eaten by hens are very limited, the content of vitamins in eggs is very small, and the color of egg yolk is very light.

Are native eggs more nutritious?

**Will native eggs, which are much higher than ordinary eggs, have higher nutritional value than ordinary eggs?

Native eggs are suitable for children and the elderly.

In the true sense, local chickens should be completely free-range, foraging in the woodland every day, and only eating natural foods such as insects and weeds. Because of the unbalanced nutrition, the eggs laid by this kind of chicken are relatively small, but because the local chickens eat more green leafy vegetables, the content of carotenoids and vitamin B2 in the egg yolk is high, so the egg yolk is larger and darker in color.

However, in fact, in addition to the eggs laid by home-raised native chickens, most of the mass-produced native eggs that are commonly found on the market are "raised by foreign chickens". Some chicken farms will release laying hens, let them move freely in the woods and cotton fields, eat some natural food like native chickens, and feed a certain amount of feed to ensure the nutritional balance of laying hens. There is not much difference between this kind of ordinary eggs and native eggs, but it is cheaper than pure native eggs and much more expensive than "foreign eggs".

The so-called "foreign eggs" are eggs laid by caged chickens, which only eat feed. This scientifically formulated feed can also contain a variety of foods and nutrients, so the nutrition of this egg is no worse than the previous two, but it is the cheapest.

1. There are four or five most common yolk colors of native eggs: orange-red, light yellow, golden, yellow-black, etc. In addition, native eggs have very high nutritional value, which can improve the blood circulation of the human body and supplement the protein of the human body, and enhance the human immunity.

2. Eggs, also known as chicken eggs and chickens, are eggs laid by hens, with a hard shell on the outside and air chambers, egg whites and yolks inside. Rich in cholesterol and nutritious, an egg weighs about 50 grams and contains 7 grams of protein. 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.
