Dried Tomato Pomace
Last updated: February 11, 2026
In This Article
Quick Summary
Dried Tomato Pomace is a processing byproduct—but not empty filler. It provides legitimate fiber plus lycopene (antioxidant), though amounts are modest. Position matters: appearing high on the ingredient list signals cost-cutting, while moderate amounts lower on the list are reasonable. Safe from ripe tomatoes; solanine concerns only apply to green tomatoes and plant stems.
What It Is
The leftover skin, pulp, and seeds from tomato processing, dried and ground. A source of fiber and lycopene.
Compare to Similar Ingredients
- vs. tomatoes: Tomato pomace is the leftover skins, seeds, and pulp from tomato processing - a concentrated fiber source - while whole tomato includes flesh and juice.
- vs. beet pulp: Both are processing by-products used as fiber sources. Tomato pomace provides lycopene antioxidants, while beet pulp is a plainer fiber source.
Why It's Used in Dog Products
Manufacturers include dried tomato pomace in dog food, treats, and supplements for several reasons:
- Inexpensive fiber source
- Contains lycopene (antioxidant)
- Adds bulk without many calories
Quality Considerations
When evaluating dried tomato pomace in dog products, it's important to understand soluble versus insoluble fiber, digestive health benefits, and stool quality. This ingredient's quality and appropriateness can vary significantly based on sourcing, processing, and the specific formula it's used in.
Provides fiber but minimal nutrition. It's essentially tomato waste from processing.
Scientific Evidence & Research
Function and Purpose
Dried tomato pomace is the by-product of tomato processing (skins, pulp, seeds) after juice/sauce extraction. Provides dietary fiber, lycopene (antioxidant), vitamins, minerals, and residual tomato nutrients. Functions as a fiber source, natural colorant, and antioxidant contributor.
Mechanism of Action
Soluble and insoluble fiber supports digestive health, stool formation, and satiety. Lycopene, a carotenoid antioxidant, reduces oxidative stress and may support prostate and cardiovascular health. Provides natural red pigmentation. Residual nutrients (vitamin C, potassium) contribute to nutritional profile. Cost-effective whole-food ingredient utilizing food by-product.
Efficacy Evidence
Good fiber source improving stool quality and gut motility. Lycopene content provides antioxidant benefits; bioavailability enhanced by processing (heat breaks down cell walls). Natural colorant without synthetic dyes. Nutritional contribution modest. Effective as part of balanced fiber and antioxidant strategy.
Safety Profile
Generally safe for dogs. Tomato plant parts (green tomatoes, stems, leaves) contain solanine (toxic), but ripe tomato pomace safe. Processed pomace from ripe tomatoes has negligible solanine. High fiber may cause loose stools if excessive. No significant toxicity concerns with proper sourcing from ripe tomatoes.
Evidence Rating: Moderate
Nutritional composition established. Good evidence for fiber and lycopene benefits. Safety well-documented when sourced from ripe processed tomatoes. Cost-effective by-product utilization. Appropriate for fiber supplementation, antioxidant support, and natural coloring in dog foods.
Label Guidance & Quality Indicators
Alternative Names
- Tomato pomace
- Dehydrated tomato
- Tomato fiber
- Tomato by-product
Label Positioning & Marketing
Common in natural, fiber-rich, or antioxidant formulas. Marketed for digestive health, lycopene content, or sustainable ingredient use. Often appears mid-to-lower ingredient list.
Quality Indicators (Green Flags)
- Sourced from ripe, processed tomatoes
- Moderate inclusion (2-5% for fiber benefits)
- Organic or non-GMO sourcing
- Part of diverse fiber profile
- Natural colorant alternative to synthetic dyes
- Quality processing (clean, food-grade)
- Combined with other antioxidant sources
Red Flags
- Excessive inclusion (>10% causing GI issues)
- Green or unripe tomato source (solanine risk - rare)
- Primary fiber source alone (needs diversity)
- Used as cheap filler
- Poor quality or contaminated pomace
- Sole antioxidant source
- Medicinal claims (prevents cancer)
Not harmful but offers little nutritional value. It's filler that provides fiber at low cost.
Frequently Asked Questions
Is tomato pomace just a cheap filler?
Not exactly. Tomato pomace (dried skins, seeds, and pulp) is a byproduct, but it provides legitimate fiber and contains lycopene, an antioxidant. It's not nutritionally empty like some fillers. However, if it appears high on the ingredient list, that could indicate cost-cutting. In moderate amounts lower on the list, it's a reasonable fiber source.
Does tomato pomace provide lycopene benefits for dogs?
Tomato pomace does contain lycopene, an antioxidant linked to various health benefits. However, the amounts in dog food are small, and lycopene absorption requires fat. Don't choose a food specifically for lycopene content—the benefits at these levels are modest. It's a nice bonus rather than a primary nutritional feature.
Are tomatoes safe for dogs?
Ripe tomatoes and tomato pomace are safe for dogs. The concern about tomatoes relates to green tomatoes and tomato plant parts (stems, leaves), which contain solanine. Commercial tomato pomace comes from ripe tomatoes processed for human food, so it's completely safe. Dogs shouldn't eat raw green tomatoes or tomato plants.
