PURIS Pea Starch Performance

Clean, functional carbohydrate designed for pet nutrition, supporting digestibility, texture, and metabolic health without common grain trade-offs.

  • Highly digestible: ~96% digestibility in dogs and cats, supporting efficient nutrient absorption.

  • Texture-enhancing: Naturally high amylose content (~30–35%) delivers firm, crunchy kibble structure.

  • Low glycemic impact: Low glycemic index (~30) compared to corn (~70) and wheat (~65), supporting steady energy and glucose response.

Dry Kibble FAQs

How does pea starch improve texture and structure in grain free kibble?

Pea starch serves as the primary natural binder in kibble, offering high amylose content (~30–35%) that creates firm, cohesive, crunchy pieces without grains or synthetic binders.  

Why is pea hull fiber used in kibble formulations?

 Pea hull fiber, made of ~80% insoluble fiber, supports stool quality, reduces calories, increases satiety, and strengthens kibble structure to prevent breakage.  

When are internal pea fibers used in kibble instead of starch?

 Internal pea fiber is ideal for high meat or low starch kibble where moisture needs to be controlled—it binds 6–10× its weight in water to improve cohesion and reduce crumbling.  

What role do whole peas or pea flour play in kibble?

 Whole peas and pea flour offer balanced nutrition and clean label appeal by combining starch, protein, and fiber in a single ingredient.  

Are pea screenings actually functional in kibble?

 Yes, pea screenings add fiber and protein economically, while supporting sustainability through whole plant utilization.  

Sustainability

Life Cycle Assessment Results | Pea Protein and Starch

Our pea protein boasts a carbon footprint that’s over three times less than some whey protein concentrates and an impressive
up to 45% lower than other plant proteins. This isn’t just a minor improvement; it firmly establishes PURIS® Pea Protein as one of the
most sustainable protein sources available today, giving your products a powerful edge.
