Natural Flavor Definition

Egg shells are porous. Although rare, it is possible for bacteria to seep through the shell of an egg and into the air sac that exists within the shell. The air pocket of an egg is located between the inner and outer membranes of the shell. This air pocket gradually grows as the egg loses moisture during storage.

When the pointed, or narrower end of the egg, is placed downward into the carton then gravity works to the advantage. It will keep the air sac in the rounded larger end of the egg which is then located on the top end of the egg, safely away from the yolk located in the center of the egg. The rounded area allows room for the natural expansion of the air sac as the egg ages.

In the rare occasion that there is any bacterial intrusion, fear of the air sac rupturing and spoiling the egg is eliminated with this proper storage.
