Rapid cooling is one of the most important factors in maintaining initial egg quality. Tests conducted on a poultry ranch in southern California show that the time required for cooling eggs is greatly affected by the container in which they are packed. Best cooling conditions are obtained when the egg has the least packaging or a container that permits maximum exposure to the cooling air. Packages which reduce exposure to the air or insulate the egg increase the cooling time.

The Okuda Brothers of Garden Grove, California, provided the necessary facilities for conducting this test.
