What is the difference between white and red eggs? 60

After eating so many eggs, do you know the difference between red eggs and white eggs? Don't buy the wrong one in the future.

Eggs should be one of the most common and most commonly eaten foods for our people, it is very nutritious, ** is also very cheap, now on the market ** is probably between, is most people can afford to consume the commodity, at the same time there are many kinds of egg practices.

The same eggs can be made into poached eggs, boiled eggs, scrambled eggs, egg custard, etc., not to mention countless foods with egg additives. There are many ways to make eggs, so many people will store some in their homes in case they need them, but most people buy eggs casually.

In fact, eggs are also divided into red eggs and white eggs, which can be well distinguished from the shell of the egg, but should you choose white eggs or red eggs? There's a lot of knowledge in that. See what the old farmer said, don't buy the wrong one in the future.

In the eyes of the older generation, only high-quality chickens can produce red eggs, so the nutrition of red eggs is higher than that of white eggs. But this is what people thought and thought in the past, is this really the case? According to relevant experts, the difference between red and white eggs is derived from a substance called protoporphyrin.

This substance can only be formed and inherited by nature, not inherited.

This also shows that no matter what feed you are fed, it has no effect on the color of the eggs, just like our genes. However, there is still a certain difference between the two in terms of structure, the protein content in white eggs will be higher than that in red eggs, and the other components are almost the same.

If you buy eggs specifically for protein, you can choose white eggs, and if you just buy eggs for cooking, you can buy any eggs. In addition to the protein content, there are also slight differences in the content structure of the two, for example, white eggs will have less protein than red eggs, and conversely, white eggs will have more yolk than red eggs.

You can choose eggs according to your preferences, if you like to eat egg whites, then you can choose red eggs, if you like to eat but egg yolks, you can choose white eggs. Now do you know how to choose eggs? Do you have any other tips for picking eggs?

What is the difference between red and white eggs? **Expensive good? Knowledge.

It's just a matter of the breed of chicken.

Some people say that the high nutrient content of red skin is a lie.

The nutritional value is all about the same.

The red-skinned eggs are the so-called firewood chickens, and the white-skinned eggs are commonly known as foreign chickens, and the red-skinned eggs are green and the white-skinned eggs are green. To figure out the difference between red and white eggs, you must first know the color of the eggshell. The color of the egg mainly comes from the pigment secreted on the surface of the hen's reproductive system, and whether the egg is a red shell or a white shell mainly depends on the breed of the hen, and the way of feeding, the choice of feed is not necessarily related.

Both eggs are equally good. Because the color of the egg depends on the breed of the hen, the breed of the hen is different, the pigment secreted by her uterine epithelium is different, and the food eaten in the process of feeding is different, so the color of the egg produced is also different. These three eggs are different in shape and color, and their nutritional value is the same.

White eggs are mostly white raw, red eggs are mostly brown chickens, and green eggs are mostly black chickens.

Egg buying tipsFirst of all, let's take a look at an egg, the feel is a little rough to the touch, not particularly smooth, such as the egg that is particularly smooth in the slow sleepiness fruit, that is, the time has been preserved for too long. If the surface of the egg is dirty, there may be only some bacteria, such as Salmonella, or even other viruses.

Smell it: normal eggs don't have any special taste, if you smell carefully, there is an abnormal or even fishy smell, it proves that the egg has rotten performance, then it is not good.

The above content refers to the Encyclopedia of Disturbing Wild Thoughts - Eggs.

1. Eggshell color.

The color of the eggshell comes from the last processing process of the egg in the hen's reproductive tract - the pigment secreted by the uterine epithelium is evenly applied to the eggshell on the white background, and whether the egg is a red shell or a white shell mainly depends on the breed of the hen, and is not necessarily related to the way of feeding and the choice of feed.

2. Nutritional value.

Whether it is a white-skinned egg or a red-skinned egg, the main nutrients are protein, fat, vitamins and carbohydrates and vitamins. The comparison of the main nutrients of the two types of eggs is as follows:

The protein content of white-skinned and red-skinned eggs is about 12%;

The fat content is slightly higher for the red skin, and slightly lower for the white skin;

There is no significant difference between carbohydrates;

The vitamin A content is higher for white skin and lower for red skin;

Vitamin E is higher in white skin and lower in red skin;

Compared with the content of other nutrients, there is no obvious difference.

According to the above comparison, it can be seen that although the main components of red and white shell eggs are different, the difference is not large.

3. Storage time.

Redskinned eggs last longer. Because red eggshells are thicker than white eggshells, they are better able to block the entry of bacteria, so they are more resistant to storage.

How to buy eggs.

1. Look at the shell: When buying eggs, pay attention to whether the egg shell is clean and complete, and whether there are damaged and moldy spots on the surface of the egg.

2. The sound of shaking water: the sound of water will appear when the fresh egg shakes, and only when the egg shakes for too long, the sound of water will appear.

3. Shine bubbles: Shine the eggs on the light, if there are large bubbles in the eggs, they are not fresh eggs.

4. Buoyancy measurement: Put the bought eggs into the water, the fresh eggs will sink to the bottom of the water, and the eggs that have been stored for a long time will float.

In addition to the difference in appearance, there is not much difference in nutritional content between white-skinned eggs and red-skinned eggs. The heme metabolism in the blood of ordinary hens can produce eggshell porphyrins, so the eggshell can be light red, while the Laihang chicken and the white rogue chicken cannot produce eggshell porphyrins, so the eggshell is white, and the color is completely determined by genetics.

In the past, red-skinned eggs were the so-called firewood chickens, and white-skinned eggs were commonly known as foreign chickens under Laiheng chickens. As for whether it is high or not, it has not been tested. But now the red eggs are not necessarily laid by the chickens, the red eggs of the chicken factory are mixed with other things in the chicken feed, and the egg skin becomes red, and the nutrition is the same as the white eggs, but because people like red eggs, they can be improved.

It is divided into differences in eggshell color, nutritional value, and storage time.

1.The color of the eggshell is different, in fact, depending on the breed of hen, the hen evenly applies the pigment secreted by the uterine epithelium to the white eggshell, resulting in a different color. That has nothing to do with the way of feeding or the choice of feed.

2.The nutritional value is different, whether it is a white-skinned egg or a red-skinned egg, the main components are protein, fat, vitamins and carbohydrates and vitamins.

The fat content was slightly higher in red skin, the content of vitamin A and E was higher in white skin and lower in red skin, and the difference in other nutrients was not obvious. Although the proportions of the main components of red and white shell eggs are different, the difference is not large.

3.Red eggs can be stored longer than white eggs because red eggs have a thicker texture than white eggs, which can better prevent bacteria from entering, so they are more resistant to storage.

Do raw eggs have to have salmonella

Not all eggs contain Salmonella, and in general, only about 10% of fresh closed eggs contain Salmonella. And bacteria are afraid of high temperatures, boiling for 8min and 10min, the bacteria outside the eggs will be killed. Of course, you can also choose raw eggs like yellow swans to eliminate salmonella from the source.

Soft-boiled eggs are a practice of eggs and are a very tasty food. But the fly in the ointment is that there will be a splinter spine of Salmonella bacteria in the soft-boiled eggs. Ingestion of food containing Salmonella may cause fever, persistent high fever, and body aches.

Salmonella is mainly found in the intestines of humans and animals and can be transmitted between animals and people, as well as between people. The mode of transmission is mainly fecal-oral transmission. Raw eggs are often contaminated with poultry manure and can easily be contaminated with salmonella.
