One common question people have about white chicken eggs is whether they are bleached The simple answer is no, white eggs are not bleached.
The color of an egg is determined by the breed of the chicken that laid it. White chicken breeds with white earlobes, such as Leghorns, lay white eggs. Brown chicken breeds with brown earlobes, like Rhode Island Reds, lay brown eggs.
When an egg is formed inside a chicken, it starts out white. In some breeds, as the egg travels through the oviduct, brown pigment is deposited on the shell. But this pigment does not penetrate the shell, so the interior of brown and white eggs is the same.
Why Do People Think White Eggs are Bleached?
There are a couple reasons why some consumers think white eggs must be bleached
-
Brown eggs tend to cost more than white eggs at the grocery store. This leads some people to assume brown eggs are higher quality and white eggs are bleached to cover up inferior quality.
-
In the U.S., all commercially sold eggs are washed before being packaged. This mandatory cleaning process uses warm water and mild detergent, not bleach. But some people think the reason white egg shells look so white must be bleaching.
Are Brown Eggs Healthier Than White Ones?
Many people believe brown eggs are more natural and healthier than white eggs. But nutritionists confirm there is no nutritional difference between white and brown eggs.
The color of the shell has no effect on the quality of the egg inside. Both brown and white eggs can have high levels of nutrients if the chickens are raised on a healthy, natural diet.
Free range chickens that eat a diverse diet and roam outside usually produce more nutritious eggs than conventionally raised chickens. The color of the egg shell makes no difference.
How to Choose Healthy, Humane Eggs
Rather than judging eggs by their shell color, consumers should focus on how the chickens were raised. Pasture-raised chickens that eat an organic, vegetarian diet and roam outdoors produce the healthiest, most humane eggs.
When shopping, look for the following labels:
- Certified Organic
- Certified Humane
- Pasture-raised
- Free range
Avoid eggs from caged chickens with no outdoor access. Their eggs are more likely to be nutritionally deficient.
Are Brown Eggs Organic?
Have you ever heard someone say “brown eggs are organic and white eggs aren’t?” This isn’t necessarily true. Remember, “organic” refers to how the chickens are raised and how the eggs are handled — whether an egg is organic or not has nothing to do with its color.
You might also hear “white eggs come from white chickens and brown eggs come from brown chickens,” but that’s an oversimplification. For example, some heritage breeds like Araucana chickens lay robin’s-egg-blue eggs. Olive eggers lay green eggs, but these chickens don’t have blue or green feathers!
