Discover our industry-standard isolated proteins, vital wheat glutens, and dietary fibers, optimized for high-durability dog dry food extrusion and precision animal nutrition.
The global dry dog food market is undergoing a seismic shift. Modern pet parents demand "human-grade" ingredient lists, clean labels, and specialized functional foods. For large-scale pet brands, contract manufacturers, and procurement specialists worldwide, securing a steady supply of premium macro ingredients is a critical operational bottleneck.
High-quality dog dry food relies not just on animal proteins, but increasingly on highly functional plant-based proteins and fibers. Raw ingredients such as Isolated Soy Protein (ISP) and Vital Wheat Gluten (VWG) are indispensable. They play structural roles in twin-screw extrusion systems, control water activity, enhance palatability, and optimize amino acid profiles to satisfy regulatory frameworks (such as AAFCO and FEDIAF).
We solve formulation, texturization, and commercial scaling challenges by positioning our integrated crop processing capacity directly at the heart of the global pet food supply chain.
Undergoing twin-screw cooking, the addition of our Vital Wheat Gluten builds a robust viscoelastic matrix. It regulates expansion ratio, guarantees kibble density, and lowers final fine particles generation to protect brand reputation.
Our low-temperature food-grade soy protein isolates provide up to 90% dry basis protein. Free from anti-nutritional factors (ANFs), they offer excellent digestibility and fill essential lysine gaps present in standard grain bases.
Soy Dietary Fiber (SDF) provides both soluble and insoluble fractions. This aids fecal consistency, hairball management, and weight management recipes, catering to high-margin pet clinical health lines.
From wheat and soybean planting bases to high-tech spray drying towers, our structural vertical integration guarantees cost stability and volume consistency for global dog dry food giants.
| Ingredient Category | Functional Key Metric | Primary Application in Dog Dry Food Production | Formulation Benefit |
|---|---|---|---|
| Isolated Soy Protein (ISP) 9000 Series | ≥ 90% Protein (Dry Basis) | Protein booster for all-life-stages dry kibbles | Replaces high-cost meat meals, optimizes crude protein values. |
| Vital Wheat Gluten (VWG-P/PS) | ≥ 82% Protein, high viscoelasticity | Binding and texturizing agent in continuous extrusion | Prevents crumbling, controls kibble density, improves kibble shape retention. |
| Soy Dietary Fiber (SDF) | ≥ 65% Total Dietary Fiber | Prebiotic and moisture binder in dietetic dog food | Enhances stool quality, increases satiety in weight-loss diets. |
| Functional Soy Protein Concentrate | ≥ 65% Protein, low antigen content | Highly digestible protein base for puppy kibble | Gentle on young digestive tracts, minimizes allergen risk. |
Developing high-quality dry kibble requires precise thermal processing and advanced material science. Modern pet foods are cooked under high temperatures, high pressures, and high shear forces (HTST). These conditions alter molecular structures and gelatinize starch.
To support this, we use the advanced Tri-Canter Separation Technology in our wheat gluten lines, imported to keep processing clean and closed. This keeps protein structures native, preserving their viscoelastic properties for the extrusion process.
For soybean processing, we operate a world-class single production line equipped with a spray drying tower from DACHUANYUAN. The result is an isolated soy protein that disperses quickly and hydrates consistently. It forms strong heat-induced gels that lock in moisture and fats during processing, preventing oil separation in high-fat pet food recipes.
Established in May 2003, Xinrui Group has developed into a multi-billion yuan industrial group integrating agriculture, plant proteins, and clean energy supply chains.
Founded in 2007 (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd), our facility manages registered capital of 100 million Yuan. We process 500,000 tons of wheat flour annually, extracting vital wheat gluten, starch A, and starch B. Starch B and pentosan are recycled directly into eco-friendly alcohol and nutrient-dense animal feed, forming a complete circular value chain.
Established in 2014 with 120 million Yuan registered capital, Kawah Oils is a leading agricultural enterprise in Shandong Province. Processing 180,000 tons of locally grown NON-GMO soybeans annually, it outputs food-grade oil, meal, isolate soy proteins, and dietary fibers. This plant houses one of the largest single spray drying lines in China.
Established in 2011 with a registered capital of 6 million Yuan, Ruichang Trading is the group's global trading engine. It exports isolated soy proteins, vital wheat gluten, and soluble fibers directly from the factory floor to international pet food producers. Direct export channels cover over 70% of our group production, integrating manufacturing and trade.
Global pet food compliance requires strict adherence to international safety standards. Animal feed imports are highly scrutinized for mycotoxins, heavy metals, microbial pathogens, and chemical residues. Xinrui Group ensures peace of mind by maintaining complete traceability from regional crop farms to the final sealed shipping container.
Our ingredients meet the requirements for clean-label, plant-based declarations across major markets, helping pet food brands streamline regulatory approvals.

We are an integrated group company named Xinrui Group combining large-scale manufacturing and global export services.
Our group manages operations through dedicated subsidiaries:
• Shandong Kawah Oils Co., Ltd: The manufacturer of isolated soy protein, producing 50,000 tons annually.
• Guanxian Xinrui Industrial Co., Ltd: The manufacturer of vital wheat gluten, producing 30,000 tons annually.
• Guanxian Ruichang Trading Co., Ltd: The direct exporter managing international sales and global shipping logs.
Our operations carry internationally recognized certifications including HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO. We also provide third-party inspection certifications from SGS or equivalent agencies upon request.
Isolated Soy Protein offers a clean, highly digestible protein source (minimum 90% dry basis) that balances the amino acid profile of grains. It serves as a functional binder, retaining oil and moisture during twin-screw extrusion to prevent dry kibble from cracking or crumbling during transport.
Yes. Shandong Kawah Oils processes only local domestic Non-GMO soybeans. Our supply chain features strict segregation from farm to processing plant, verified under Identity Preserved (IP) Non-GMO protocols.
We supply materials in standard multi-wall paper valve bags (typically 20kg or 25kg) and bulk super sacks (jumbo bags). Containers are packed with or without pallets, based on our client's bulk unloading requirements.
