Why is the yolk red for grain eggs, and why are some eggs red

The reason for the red yolk of the five-grain egg is that the five-grain egg adds some pigment dyes to the feed, artificially turning the yolk red, acting as a native egg, and making huge profits. The yolk of some five-grain eggs is naturally red, which is caused by chickens eating some special grass seeds or feed containing red pigment, which is harmless to human health and can be eaten with peace of mind.

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.

The market sells whole grain eggs with pink yolks. is edible.

It's all good! But I think that health preservation still requires whole grains, and health care products are not a necessity for normal life after all!

The yolk of the egg is orange. The yolk is the yellowed part of the inside of the egg, as opposed to the white. Most of the protein in eggs is concentrated in the egg whites and egg membrane, while the rest of the nutrients are concentrated in the yolk.

I opened the eggs, is the yolk loose normal.
