Pumpkin & Sweet Potato Purees for Pet Food (Texture & Digestibility)

Why pumpkin and sweet potato are popular in pet food

These two ingredients sit at the intersection of function, manufacturing practicality, and consumer appeal. Pumpkin is strongly linked to digestive support narratives and “fiber for stool quality.” Sweet potato often appears in limited-ingredient and premium positioning, sometimes associated with gentle carbohydrate sources. In manufacturing terms, both contribute solids and viscosity, which can help build a thicker gravy, create a more cohesive soft chew, or support a topper texture. They also provide a recognizable ingredient name on the label—an advantage in premium retail channels.

Format selection: aseptic vs frozen (and why pet food plants often prefer aseptic)

Pumpkin and sweet potato purees are commonly available in frozen or aseptic formats. Frozen can work well when plants are built around frozen receiving and thawing workflows, but it introduces cold-chain cost, storage footprint, and thaw management. Aseptic purees are attractive because they can be stored ambient (depending on supplier specs and packaging), simplify receiving, and reduce spoilage risk when handled correctly. In high-throughput pet food plants, aseptic packaging also supports cleaner, more HACCP-friendly handling because the ingredient is delivered in a sealed system designed for stability. Whichever format you choose, ensure your spec and handling rules align with your production environment.

For general storage and shelf-life planning across formats, see Topic 097. For packaging options (drums, totes, bag-in-box), see Topic 096.

Critical spec #1: viscosity (the main cause of line surprises)

In pet food manufacturing, viscosity is often the “silent variable” that creates downtime. Pumpkin and sweet potato viscosities can vary widely even when °Brix/solids appear similar. Viscosity influences pump selection, pipe pressure, depositor behavior, and mixing energy. In wet foods, it affects gravy thickness and how the product coats meat chunks. In soft chews, it affects depositing and set behavior. For consistent manufacturing, define a viscosity range that your equipment can handle, and verify it lot-by-lot when needed. If you have multiple plants, standardizing the viscosity spec is even more valuable.

Critical spec #2: particle size and smoothness

Particle size affects both texture and processing. A smoother puree may be easier to pump and deposit, and it can create a more uniform chew. Coarser purees may support “real food” texture cues, but they can clog small fitments, contribute to sedimentation in gravies, and create variability in depositor performance. Decide early whether the product needs a “smooth” or “rustic” texture, then specify particle parameters accordingly. For sensitive lines, smoother is usually safer.

Where pumpkin/sweet potato fit in kibble manufacturing

In dry kibble, these ingredients may be used as part of the wet mix prior to extrusion, or sometimes in coating systems (less common for high-puree inclusions). The main processing constraints are extrusion behavior and product expansion. High sugar or high solids can shift browning and flavor development during extrusion, and added viscosity can change dough handling. Inclusion rates are usually modest compared with wet foods or treats. The best practice is to validate in pilot extrusion trials and monitor expansion, density, and palatability outcomes.

Where pumpkin/sweet potato fit in wet pet food and toppers

In wet and topper products, pumpkin and sweet potato purees are often used more visibly. They can build gravy thickness, improve cling to chunks, and create a “homestyle” appearance. Retort processing can change color and intensify cooked notes, so sensory validation should be done using the real retort profile. The puree’s viscosity and particle size also determine whether the product pours and fills consistently. In toppers, the goal is often a spoonable texture; in gravies, it’s a pourable but clingy system. Matching puree specs to that target texture is essential.

Soft chews and gels: pumpkin is a workhorse ingredient

Pumpkin is widely used in digestive-positioned soft chews. Its solids and texture can support chew structure and “fiber” narratives. Sweet potato can also be used, but it may behave differently depending on solids and starch profile. In these systems, water activity and shelf stability are the primary risk. Purees bring water; your binder and solids strategy must keep the product stable without losing chew softness. Many successful products treat the puree as both a flavor/identity input and a structural component.

For gel and soft chew workflows using purees, see Topic 078.

Palatability: what these ingredients do (and don’t) do

Pumpkin and sweet potato rarely drive palatability on their own. In most pet foods, palatability is dominated by proteins, fats, and savory aromas. These vegetable purees are typically supportive: they influence texture and moisture perception, and they can help carry flavors in gravies and treats. For dogs, acceptance is usually straightforward; for cats, vegetable-forward profiles may be less influential. Validate palatability early, and don’t assume human preferences translate directly to animals.

Handling and storage: why aseptic performance depends on plant discipline

Aseptic packaging can deliver stable purees, but once opened, time and sanitation rules matter. Define receiving inspection steps (verify packaging integrity and lot coding), connection practices (clean fitments, correct closures), and time-in-use rules to prevent contamination. For frozen purees, thaw management is a critical risk point. In pet food plants, the most common failures are not ingredient quality at shipment, but handling errors after receiving. Build simple SOPs that operators can follow consistently.

Procurement: specs and documentation to request

For pumpkin and sweet potato purees, procurement should lock down: format (aseptic or frozen), packaging type and fitments, solids/°Brix range, viscosity range, particle size/screen parameters, and pH (when relevant). Documentation typically includes COA, allergen statement, country of origin, and traceability details. If your product claims are sensitive (e.g., organic), certifications must be included and current. Standardizing these requirements reduces qualification time, especially across co-manufacturers.

Next steps

If you share your pet food format (kibble, wet/canned, topper, soft chew), target texture (pourable gravy vs spoonable topper vs chew bite), process method (extrusion/retort/deposit), desired packaging format, destination market, and documentation requirements, PFVN can recommend pumpkin and sweet potato puree options and specification controls that reduce downtime and improve consistency.
