Explore our core plant-based functional isolates and structured binders
Established in 2003,
With a massive registered capital of 100 million Yuan, our plant processes over 500,000 tons of premium wheat flour annually. By utilizing self-reliant wheat cultivation bases, we create a closed-loop circular economy. Our primary products include high-grade Vital Wheat Gluten, Wheat Starch A, and Wheat Starch B, alongside animal feed and industrial ethanol derived from pentosan and starch B.
To achieve full integration of manufacturing and international trade, Guanxian Ruichang Trading Co., Ltd. was established in 2011 with a registered capital of 6 million Yuan. Today, over 70% of our group's premium output—including isolated soy protein, vital wheat gluten, soluble dietary fiber, vermicelli, and ethanol—is exported directly to buyers across the Americas, Europe, Southeast Asia, and the Middle East.

Providing global buyers with guaranteed volumes, cost predictability, and zero-carbon ambitions
In the modern agricultural processing market, price volatility and energy supply stability are critical challenges. Xinrui Group mitigates these risks by establishing a closed-loop Industrial 4.0 Ecosystem. Our headquarters houses dedicated municipal cogeneration, urban heating, and gas supply systems. This ensures that both Guanxian Xinrui Industrial and Shandong Kawah Oils operate with highly reliable, self-generated heat and power.
By controlling the energy inputs, our factory maintains continuous operation, shielding international buyers from production halts due to localized power limits.
Our ecological design follows a zero-waste philosophy:
Why mechanical isolation makes the difference in gluten protein viscoelasticity
Unlike traditional washing systems that stress gluten polymers, the imported Tri-Canter Separation Technology uses precise three-phase centrifugal force. This process separates light starch, heavy starch, and gluten protein in a closed, hygienic system without chemical degradation.
The gentle mechanical extraction preserves the native disulfide cross-links of the gliadin and glutenin molecules. This results in an excellent water absorption rate (150-180%), giving the final product outstanding viscoelasticity.
Operating in a completely closed loop prevents microbial ingress. It maintains a consistent protein content of ≥75% (dry basis), with ultra-low ash and moisture content. This delivers reliable batch-to-batch consistency for industrial food formulation.
The plant protein industry is evolving from simple physical extraction to advanced functional engineering. Xinrui Group is leading this shift by investing in molecular-weight targeting research. Our goal is to expand the range of wheat gluten performance through enzymatically modified variants and clean-label texturizers.
By optimizing the ratio of glutenin (which provides elasticity and strength) to gliadin (which provides extensibility and viscosity), we are developing specialty grades tailored for high-speed industrial baking and high-moisture extrusion (HME) technologies.
Additionally, we are exploring eco-friendly by-product recovery. This includes isolating soluble pentosans for dietary fiber applications and turning low-solubility proteins into bio-plastics. This strategy ensures our factory remains a benchmark for sustainable industrial practice.
How Vital Wheat Gluten acts as a functional backbone across diverse global industries
Strengthens weak flours by improving gas retention, increasing crumb softeness, and maximizing loaf volume in artisan and sandwich breads.
Creates realistic fibrous textures in plant-based burger patties, sausages, and steaks through its natural heat-coagulating properties.
Acts as an allergen-safe, highly digestible protein binder. Ideal for gravies in wet canned food and extrusion shaping in dry kibble.
Utilized in pelletized feed (VWG-PS pellets) to improve water stability and prevent feed dissolution, ensuring high absorption rates for aquatic species.
Combining wheat gluten expertise with China’s premier non-GMO soy protein processing line
Established in 2014 with 120 million Yuan in registered capital, Shandong Kawah Oils Co., Ltd. is a leading enterprise in agricultural industrialization. Our state-of-the-art facility processes 180,000 tons of domestic non-GMO soybeans annually.
By controlling every stage from cultivation to extraction, Kawah Oils produces premium non-GMO soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and dietary fiber. Our facility features a high-capacity spray drying tower from DACHUANYUAN, which powers the largest single soy protein isolate production line in China.
This structural alignment allows us to supply food manufacturers with integrated solutions. By combining the elastic matrix of Vital Wheat Gluten with the emulsifying and gel-forming properties of our Isolated Soy Proteins, we help developers create superior texture profiles in meat, dairy alternatives, and nutritional beverages.
Critical specifications technical buyers must evaluate to ensure formulation success
Critical for bakery structure. Vital Wheat Gluten must form a cohesive, highly elastic dough when rehydrated. Our tri-canter process protects the native protein structure, preventing mechanical degradation and keeping glutenin strands intact.
Premium gluten should absorb 1.5 to 1.8 times its dry weight in water. Higher water absorption increases yield efficiency in industrial baking and improves succulent texture in processed meats and meat analogues.
A consistent particle size is vital for uniform hydration. If the particles are too coarse, they hydrate unevenly, leading to dry spots in baking. If they are too fine, the powder can clump. We ensure a standardized 80-mesh powder profile.
Meeting strict international food regulations with certified processes
To serve demanding global supply chains, we maintain a comprehensive quality management system. Our production and logistics facilities are audited and certified to meet major international standards:
Additionally, we supply custom test certificates (SGS, Intertek) upon request to streamline customs clearance in target markets.

Critical engineering and logistics questions answered by our application specialists
We are a fully integrated group company named Xinrui Group, managing both manufacturing and exporting operations. Our production divisions include:
• Shandong Kawah Oils Co., Ltd: Manufacturer of isolated soy protein (Annual capacity: 50,000 tons).
• Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology): Manufacturer of vital wheat gluten (Annual capacity: 30,000 tons).
• Guanxian Ruichang Trading Co., Ltd: Our dedicated export arm handling direct global logistics.
Our facilities comply with major global food safety standard. We hold verified certificates for HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO. We also cooperate with third-party testing services like SGS to provide custom certificates upon request.
Our Vital Wheat Gluten has a shelf life of 24 months when stored in original, unopened bags. It should be kept in a cool, dry warehouse below 25°C with a relative humidity under 60%. To maintain optimal quality, avoid storing near strong odors or direct sunlight.
VWG-P is a fine, 80-mesh powder designed for rapid hydration. It is commonly used in industrial baking, milling, and meat formulations. VWG-PS consists of compacted pellets, which are preferred in the aquaculture and animal feed industries. The pellet form reduces dust, makes bulk handling easier, and improves stability in aquatic feeds.
Our non-GMO promise is backed by our strict Identity Preservation (IP) program. We source raw soybeans from domestic planting bases that only grow certified non-GMO seeds. We test each incoming batch using PCR testing, and we maintain complete process separation in our factories to prevent cross-contamination.
Our standard MOQ for international shipments is 1 FCL (Full Container Load), typically carrying 20 to 22 metric tons depending on the product packaging (e.g., 25kg bags or bulk super sacks). For standard specifications, our lead time ranges from 15 to 21 days from order confirmation to port delivery.
