Natural flavors are aroma compounds added to pet food to improve palatability rather than provide meaningful nutrition. Under AAFCO terminology, they may come from plant or animal tissues. One of the most common natural flavor sources is animal digest, a hydrolyzed material sprayed onto kibble to enhance smell and taste acceptance.
| AAFCO Term | Natural Flavor / Animal Digest |
| Source | Animal or plant tissue |
| Function | Palatability enhancer |
| Nutritional Value | Minimal |
| Use Rate | <2% |
| Debate Level | Moderate |
Natural flavors are generally acceptable when they are clearly sourced and used only for taste improvement. The main weakness is that the label term can be broad, which reduces transparency for guardians trying to identify the exact raw material origin.
What Is Animal Digest?
Animal digest is a liquid or dry flavor concentrate made by chemical or enzymatic hydrolysis of animal tissues. Under AAFCO definitions, many animal tissues may be used except hair, horns, teeth, and hooves. It is most often applied as a coating to dry kibble after extrusion.
