Dry Kibble

Color Incorporated Before Extrusion

Adding color directly into the kibble dough before extrusion exposes it to the full heat, pressure, and shear of the extrusion process — a demanding combination that requires colors proven stable under those specific conditions.

‍

Post-Extrusion Coating Applications

Alternatively, color can be applied as part of a post-extrusion coating or a palatant spray, avoiding direct exposure during extrusion — though this approach introduces its own considerations regarding coating adhesion and even distribution across each piece of kibble.

Wet Food and Canned Products

Retort Thermal Processing

Canned and pouched wet foods typically undergo retort processing to ensure shelf stability, exposing color to intensive, sustained heat — similar in principle to, though generally more demanding than, the pasteurization processes discussed in our dairy series.

‍

Moisture-Rich, Often Meat-Based Matrices

Wet food's high-moisture, protein- and fat-rich matrix behaves differently than a dry or low-moisture system, requiring colors compatible with both the retort process and the specific base ingredients of the formulation.

Treats and Chews

Baked and Extruded Treats

Baked pet treats share direct formulation parallels with our bakery series and face similar heat exposure and browning considerations. In contrast, extruded treats face the same extrusion-specific stress covered later in this series.

‍

Soft Chews and Jerky-Style Treats

Soft chews often share a formulation base more closely aligned with nutraceutical gummies or confectionery gels. Dehydrated jerky-style treats introduce a different set of moisture-removal and extended-drying-time considerations for color stability.

Matching Color Form to Format

Water-Soluble vs. Oil-Dispersible Choices

As in every category covered in this series, matching a color's solubility profile to the specific pet food format — wet, dry, coated, or baked — remains the foundational first step before addressing any format-specific processing stress.

‍

Coordinating Across Multi-Component Products

Many pet food products combine multiple components — kibble with visible color-coded pieces, or treats with a colored coating over a differently colored center — requiring color selection to ensure visual coordination across the entire product, not just a single component in isolation.
