Technical Abstract: Phenolic compounds have numerous health benefits when included in the human diet and have emerged as a functional food and feed additive. Current sources of phenolics include commodity grains such as corn, oat, and wheat but may also be obtained as a co-product from agricultural residues and other low-cost plant material. The phenolic compounds are preserved by encapsulation which inhibits degradation. Saturated lipids were used as a digestible capsule to protect phenolic compounds from oxidation. The encapsulated materials were produced as an aqueous emulsion that could be sprayed onto feed pellets and extend the bioactivity of the phenolic compounds. The lipid coating stabilized the compounds providing extended shelf life and could mask the organoleptic properties to prevent feed aversion.
