Even the ancient Romans and Greeks valued them for their rich taste and protein-rich profile. If you have not tried beyond a standard white egg, it’s time for you to explore the different types of eggs available across the globe.
This article discusses the wide varieties of eggs and their characteristics to give you endless possibilities for cooking egg-based dishes.
What is an Egg, and Why do Eggs have Different Colors?
According to Britannica, “An egg is a content of the hard-shelled reproductive body produced by a bird, considered as food”.
In simple terms, edible eggs (suitable for humans) are those laid by female birds like chicken, quail, duck etc., primarily for multiplying their species. Eggs consist of a hard shell as the outer cover, albumen or white and yolk in the center. Although the entire egg is rich in proteins and vitamins, it is the yolk that scores high in nutritional value.
Now coming to the color of eggs, you might have noticed different colors like brown, white, green etc., in your local stores or supermarkets. Contrary to assumptions, colored eggs are no different from the standard white ones in nutritional value or edibleness. The color results from the genes of the bird species or the breed.
For instance, breeds like Plymouth rock hens lay brown eggs, while the regular leghorn chickens lay white eggs. Other breeds like Ameraucana lay blue eggs, and black copper Maran lay dark chocolate colored eggs.
Interestingly, all eggs start out white in the initial phases and get their pigment only as the egg passes through the bird’s uterine tube or the oviduct!!
Classification of Eggs as Per Purchasing and Labelling Standards:
Walk into a supermarket aisle, and you are likely to find different kinds of eggs with labels such as “free-range”, “organic”, etc. This section helps you understand the differences between them:
These are the common types of eggs you find in the supermarket or local stores. The eggs come from hens which are raised in dark and crowded coops. These birds are fed with grain-based foods and even treated with antibiotics and supplements to raise production. Although the living conditions of hens are harsh, the eggs are quite nutritious and delicious too.
Cage Free Eggs:
As the name suggests, these eggs come from birds that enjoy little space to roam around rather than in cramped cages. They also get nest boxes to rest and lay eggs. Though the eggs are not as nutritious as conventional eggs, the humane farming practices give them a better edge.
Free Range Eggs:
These are the eggs that come from hens having access to the outdoors. This doesn’t mean the hens are free to move around anywhere they desire. They only have access to a limited, fenced area and enjoy some sunlight.
Farmers can label their eggs as “organic” only when the birds strictly eat organic fodder. Unlike commercial eggs, organic eggs are free from antibiotics, steroids etc., unless otherwise, the birds require special medication to treat a specific disease.
Vegetarian Fed Eggs:
Vegetarian eggs are those which from hens that are fed only a plant-based diet. These hens live indoors and have no access to worms, insects, or any meat by-products.
These are eggs fortified with Omega-3 fatty acids by feeding the hens with a special flax-based diet. The eggs offer 12 times more omega acids than conventional eggs and offer essential omega acids like ALA, EPA and DHA.
Pasteurized eggs are gently or lightly cooked eggs to reduce the risk of foodborne illnesses. These undergo the process of pasteurization at a certain temperature in shells.
These are industrial egg products which are sold in many forms like pre-peeled eggs, peeled hard-boiled eggs, precooked friend eggs, premade omelets etc. They are not very healthy due to the use of preservatives and artificial cooking techniques.
