You Ask, I Answer: Omega-3 Fortified Eggs

What is the process exactly in adding Omega-3 to eggs?

How is this done?

I know the eggs are "fortified" but what does this mean?

Before I get to your actual question, this is a good time to point out the difference between fortification and enrichment.

When enriching a food or ingredient (for instance, white flour,) food manufacturers are adding back nutrients that were already present in that food or ingredient prior to processing.

Fortification, meanwhile, entails the addition of one or more nutrients that are not inherently part of that food or ingredient.

Similarly, adding higher quantities of a nutrient than what is naturally present in a food or ingredient also falls under the "fortification" umbrella.

As far as Omega-3 fortified eggs, it is very simply done by adding food sources of Omega-3 to chicken feed -- usually fish oils or flax.
