Why are some eggs redhearted? What is the difference between red and yellow eggs

One reason is to eat eggs laid by chickens with added pigments, and another reason is that eggs with red hearts are native eggs. Red eggs refer to some farms deliberately adding some pigment dyes to the feed, artificially turning the egg yolk red, acting as a native egg, and making huge profits. Long-term consumption of this egg is harmful to the body.

Some local chickens lay egg yolks that are red, which is not harmful to human health. Native chickens are chickens fed coarse grains such as sorghum, sweet potatoes, corn, potatoes, taro and yams. The shell of artificially processed eggs is rougher.

What is the cause of red heart eggs.

1. Pigmenting.

Red heart eggs may be the laying hens in the process of feeding to eat the feed with added pigments, and then in the process of continuous accumulation to promote the egg yolk to appear red, belongs to a kind of artificial pigment addition, after eating may cause a certain impact on human health.

2. Naturally formed.

Red eggs may be naturally formed, if the laying hens in the process of raising sorghum, corn, yam and other feeds, the natural pigments contained in them will be deposited in the eggs, thus forming red eggs, which belong to a healthy egg.

3. Selection method.

The process of egg selection should be judged according to the luster, feel, and hardness, the luster of normal eggs is more natural, and the surface of the eggshell is relatively smooth, and the texture is relatively hard, while the artificially processed eggs are dull in color, rough in feel, and easy to break.

Eggs are a food that we eat a lot, and some eggs have a red yolk when scrambling eggs or other fried eggs. This is mainly due to the fact that some chickens have different breeds and eat different grains, so it will affect the color of the yolk of the egg.

The color of the egg yolk is related to the food that the chicken eats, and the chicks that grow up by preying on small insects and eating whole grains have a high nutritional value of the eggs, which is characterized by a slightly reddish color of the egg yolk.

Egg hearts are just different from what they eat, and they are not much higher in terms of nutrition, but most of the red hearts have a tight texture and taste better.

By artificially increasing the redness, the chicken feed was added with galisin red. And Garisin red is actually a carotenoid-like pigment.

Why are some eggs redhearted? This is due to the fact that the ingredients in the feed that the chickens eat are different, so there will be red hearts.

Usually everyone will judge whether it is a native egg or a foreign egg according to the color of the egg yolk, but in fact, this is often related to the dose of cantharidan added to the chicken. According to the conclusion of the 2010 evaluation of cantharidan dosage by the European Union Food Safety Authority (EFSA), we can see that cantharidax added to the feed will be ingested into the human body through food, and the current use will not cause food safety hazards.

As one of the pigments of the carotenoid category, cantharidan can be quickly metabolized, so even if the human body ingests a little bit every day, there is no possibility of accumulation in the body.

From this point of view, the addition of carotenoids to the feed should not pose a food safety risk. Isn't it the same as the seasoning we add when we cook rice in order to get a better color, flavor effect? Compared with the food deep processing industry in the current market, in order to win the taste, color, longer shelf life and so on, a large number of additives marked (implicitly not labeled) on the outer packaging are safer.

Some chickens prey on small insects and grow up eating whole grains, and eggs are very popular because of their high nutritional value, but they are characterized by a slight red yolk, which is a normal red heart egg. Instead of learning the means of nourishment, some people are driven by economic interests to add some dyes to the feed, usually using Sudan dye that dissolves in fat. Because Sudan dyes are soluble in fat, and egg yolks are lipids, they are deposited in the egg yolk to turn orange or dark red and other different colors, which is called harmful "red heart eggs".

Red heart egg refers to the addition of feed carotene products to egg and poultry feed, so that the egg yolk presents a certain red color, and carotene has an important health care function. Since the 70s of the 20th century, red heart eggs have been widely welcomed in the European market and have always been the main choice of consumers. A large number of studies have shown that cantharidanthin, the main component of red pigment for feeding, is an essential function for coloring poultry eggs.

In vitro tests have shown that cantharidan is also a strong singlet oxygen scavenger, which is more effective than -carotene or zeaxanthin, which can slow down free radical oxidation, or become an antioxidant with broken chains during the peroxidation of lecithin liposomes.

The yellow color of egg yolk is mainly a carotenoid – lutein. The more yellow the color, the higher the lutein content.

It's basically all about feeding pigments, and the people who buy them don't care, and they even think that red heart eggs are a good thing, CCTV has already passed, and Guangzhou has also cracked down, but it didn't take long for everyone to forget about it, and it was back to the past.

Laying hens that eat pigments, even the chicken's ** will be red... It goes without saying that long-term consumption of people has anything to the body.

1. Red eggs are a kind of eggs with a commercial name, in fact, red eggs and yellow eggs are ordinary eggs, but red eggs are eggs laid by chickens based on insects, grasses and other free-range chickens, because the body contains more lutein, which is the so-called native eggs, but whether it is the most nutritious egg or not, there is no specific answer from science. The average yellow-hearted egg is mainly the eggs laid by raised chickens.

2. However, some people think that the eggs of red heart eggs are more nutritious, but in fact, in order to adjust the color of the egg yolk, you can change the color of the egg yolk by adding other things to the feed. For example, natural carotene, marigold powder, paprika powder, seaweed powder and other synthetic substances.

3. Red eggs are not more nutritious than yellow eggs, this is a place that needs to be understood, especially some old people like to buy eggs, eggs are mainly eggs laid by some free-range chickens, they eat grass, insects and other foods every day, compared to the eggs laid by chickens with standardized and safety supervision, eggs may not be more nutritious and healthier.

The difference between red heart eggs and yellow heart eggs is that red heart eggs are produced by chickens that eat whole grains, which are green and pollution-free. Also known as chicken eggs, 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.

What is the difference between red and yellow eggsThe eggs of the red heart are stupid eggs, the kind of eggs laid by the free-range chickens at home. Yellow-hearted eggs are chickens raised on feed in chicken farms and lay eggs.

There may be two reasons for the appearance of blood-colored egg whites, one is the severe inflammation of the fallopian tubes caused by E. coli infection in the hens, and the other is the addition of problematic feed during the feeding process. Hens do not come to menstruation, the so-called "insect eggs", laying hens in the process of raising is impossible to feed all insects, can only be added to the feed of insects. If blood egg whites appear, members of the public are advised not to consume them.

There are 3 possible reasons why egg whites can turn red: the chicken is sick, the chicken has eaten the problematic feed, or the egg has gone bad after being stored for too long. Eggs are animal products, is an active substance, there are many uncertain factors, its preservation is very important, and at present, there are some non-standard places in the production of eggs, egg products do not need to be tested before marketing, these need to be gradually standardized by the industry.

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

Sound of shaking water: Fresh eggs shake so that there is no sound of water, and only when eggs that have been shaking for too long will appear when they are shaking.

Bubbles: Expose the egg to light, if there are large bubbles in the egg, it is not a fresh egg.

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