Advanced functional protein selections engineered for high binding capacity, structural integrity, and nutritional excellence.
In the modern food processing industry, plant-based proteins have shifted from alternative ingredients to key functional components. Vital Wheat Gluten (commonly known as Gluten Flour) represents a critical biological polymer, appreciated by food scientists for its unique viscoelastic, binding, and structuring capabilities. As global supply chains face volatile raw material costs and fluctuating agricultural yields, establishing direct factory partnerships with stable, certified, large-scale processing facilities has become essential for procurement and formulation departments.
Wheat gluten’s structural power lies in its complex protein composition, chiefly composed of gliadins and glutenins. Gliadins contribute cohesive properties and extensibility, whereas glutenins provide elasticity and mass strength. This synergistic balance is critical for baking applications, aquaculture feed optimization, and the production of next-generation plant-based meat replacements. At the same time, isolated soy protein works alongside wheat gluten as a highly digestible, emulsion-forming solution that guarantees physical stability and moisture retention in meat preparations.
As a premier manufacturer processing over 500,000 tons of wheat flour annually, Guanxian Xinrui Industrial Co., Ltd. (operating under the global trade arm of Guanxian Ruichang Trading Co., Ltd. and parent firm Xinrui Group) provides complete circular economy industrial integration. From custom milling of non-GMO wheat grains to high-tech wet separation processing, our integrated plant operations ensure that every shipment delivers reliable protein purity, water hydration indexes, and cross-linking properties.
The core differentiator of Xinrui Group is our closed-loop agricultural processing chain. Located in Guanxian, Shandong, China, our industrial park bridges cogeneration energy plants, municipal water resources, agricultural plantation, and deep biochemical processing.

Founded in 2007 (with original origins dating back to the establishment of Xinrui Group in May 2003), our industrial campus occupies over 1,000 mu. Driven by a registered capital of 100 million Yuan, we have pioneered the introduction of tri-canter separation technology in wheat gluten production.
Unlike traditional Martin processing methods, our advanced tri-canter separation line isolates starch, protein, and pentosans in a highly clean, closed environment. This preserves the functional integrity of wheat protein, preventing thermal denaturation and microbiological degradation. The resulting Vital Wheat Gluten features superior hydration and viscoelastic qualities, ideal for high-speed industrial baking and feed mills.
Through our trading arm, Guanxian Ruichang Trading Co., Ltd. (est. 2011), we export over 60%-70% of our group’s production capacity directly to clients across North America, the European Union, Southeast Asia, South America, and the Middle East. By unifying industry and trade, we offer direct factory pricing, secure logistics control, and direct technical support.
How our Gluten Flour and plant proteins optimize yield, water binding, and structural texture across industrial applications.
Adding our Vital Wheat Gluten to standard baker's flour boosts water absorption and crumb elasticity. It reinforces gas retention in dough, allowing longer proofing times and improving loaf volume. This is essential for clean-label, high-fiber, and whole-wheat baking formulas where structure can be compromised.
With high digestibility and a protein content exceeding 75%, our Vital Wheat Gluten serves as an ideal binder for aquaculture and shrimp feed. Its viscoelastic properties ensure pellet integrity in water, preventing nutrient leaching and keeping water systems clean.
Combined with our isolated soy proteins (such as the 9007B-C emulsion type or the 9020 injection type), vital wheat gluten creates fibrous chewiness in vegetarian meats. It binds fat and water, reducing cooking loss and providing a meat-like bite.
For premium wet pet foods, our gluten flour acts as a natural binder and texturizer, creating uniform chunks in gravy. It is easily digestible, hypoallergenic, and provides a stable source of vital amino acids like glutamine and proline.
By producing pure wheat starch alongside gluten, we support paper manufacturing, textile sizing, and pharmaceutical binder applications. Starch B and pentosan streams feed our industrial-grade bio-ethanol production, completing our zero-waste initiative.
Beyond food and feed, our gluten proteins are utilized in sustainable packaging, biomaterials, and plant-based adhesives, offering an eco-friendly alternative to petroleum-based polymers.
Established in 2014 under a registered capital of 120 million Yuan, Shandong Kawah Oils Co., Ltd. is our specialized non-GMO soybean processing facility. The facility extracts oil, low-temperature meal, isolated soy proteins, and dietary fiber in an integrated production process.
Our core soy protein processing line features a state-of-the-art spray drying tower designed by DACHUANYUAN, representing the largest single-line drying capacity in China. This advanced engineering ensures uniform particle size, excellent dispersion, and zero heat-spot denaturation, delivering high emulsification and gelling characteristics.
By sourcing raw materials from local non-GMO soybean cultivation bases, Kawah Oils provides complete traceability from farm to factory. Our production lines are separated from GMO processing channels, maintaining identity preservation (IP) status across our entire catalog.
We verify and audit our soy supply chain using PCR testing at accredited laboratories. Through strict crop sourcing protocols, we manage raw materials from planting to harvest, storage, transport, and final processing, meeting demanding B2B raw material standards globally.
Our facilities are audited to meet international standards for food safety, ethical sourcing, and product purity.
Watch our production lines, raw material silos, and quality testing labs in action.
At Xinrui Group, our technological roadmap focuses on improving separation efficiency and maintaining natural protein structures. Traditionally, the wet extraction of wheat gluten (using the Martin Process or Batter Process) required high water volumes, which generated large amounts of wastewater and mechanical stress on the gluten complex. Our integration of European three-phase centrifugal separation (Tri-canter technology) has optimized this process:
Maintaining this low-temperature process is critical. If the temperature exceeds the denaturation point during drying, the disulfide bonds within the glutenin polymers break down prematurely. This loss of elasticity impairs the dough's gas-holding capacity in bakeries and reduces structural integrity in aquafeeds. By keeping temperatures low, our Vital Wheat Gluten provides consistent performance across global industrial production lines.
Transporting plant proteins across international borders requires meeting diverse regulatory standards. Through Guanxian Ruichang Trading Co., Ltd., we manage exporting, customs clearance, and quality verification to ensure compliance in your destination market.
