I needed clarification as I too was confused on the difference:
What’s The Difference?
Pastured eggs come from hens that are born and raised on a pasture. This vast expanse of chicken utopia allows our feathered friends to walk and prance about a large pasture while eating directly from the land – just as Mother Nature herself intended. The end result is pastured eggs consisting of richer yolks and livelier whites.
Pasteurized eggs, on the other hand, refers to the process of pasteurization, which consist of heating the egg for a set amount of time before immediately cooling it down to combat spoilage resulting from microbial growth. An example of this would be heating an egg yolk in the microwave to kill pesky bacteria without actually cooking the yolk. This is a process that’s fairly common when whipping up a batch of mayonnaise.
As you can see, the terms “pastured eggs” and “pasteurized eggs” might sound similar when spoken aloud, but they mean two incredibly different things.
