2. Types of Eggs

How the hens were raised and fed determine the type of eggs they lay. Here is a quick look at the types of eggs available in the local market today.


3. Brown versus White

Many people think that brown eggs are way better than white eggs. Contrary to that popular belief, eggs, regardless of its color, have almost the same nutritive value and quality.

The hen’s diet is the main reason for its egg yolk’s color. Hens fed with natural yellow and orange pigmented feeds produces bright yellow yolk while others who are fed with white cornmeal and alfalfa produce gives a lighter medium yellow yolk. Producers often add marigold petals to hen feed to improve its yolk color.

6. Cloudy White

Many discard eggs with an apparently cloudy egg white. While it looks like a spoiled egg, it is actually a sign of an egg’s freshness. Cloudy egg whites are actually carbon dioxide trapped in the egg. It had a short time escaping the egg through the shell since it is newly hatched.

Speaking of egg spoilage, there is a limited way of finding out if your eggs are spoiled. The famous water test only shows whether the egg is old or fresh. To be sure about it, crack it open and if it smells bad, it is definitely spoiled. Reddish brown spots in egg whites are indicators as well that the egg is spoiled and must not be consumed.

In the Philippines, eggs are being cured in a mixture of mud, huge amount of salt, and lots of patience and time.
