Experts have revealed the answer: Cracking an egg opens up a different colored “yolk”: yellow, orange, red. What’s the difference? Does it affect the health of the person eating it?
Eggs are an essential part of the modern diet. On average, Americans consume about 300 eggs per year. However, in addition to the differences in egg breeds, the color of the egg yolk also varies greatly. Some eggs are bright orange, while others are pale yellow. Experts point out that these differences in color are due to the diet and nutrients of the hens, but do not affect human health.
According to the New York Post, research by Dr. Richard Blatchford, an animal science and poultry research expert at the University of California, says that while extreme colors are rare, depending on the farm, the color of the egg yolk can range from almost white to a deep red, mainly due to the hen’s diet.
Egg yolks often use the “DSM Yolk Color Fan” as their color evaluation standard, which is a 16-level color panel that can be compared to the color of an egg yolk.
Dr. Sunoh Che, assistant professor of poultry management at the University of Maryland, explains that a hen’s diet and nutrition are the main factors that determine the color of her egg yolk.
The bright red yolks of eggs come from hens that primarily eat grass, as they get protein from insects and carotenoids and lutein from plants.
A pale yellow yolk indicates that the hen’s main diet is wheat, barley, or white corn.
A bright yellow yolk means the hen was fed a diet primarily of corn or alfalfa.
Orange or dark orange egg yolks usually come from free-range hens.
However, although the สมัคร ufabet กับเรา รับโบนัสทันที color of the egg yolk reflects the composition of the hen’s diet, it does not affect the nutritional value of the egg itself.
